The Best Business VoIP Providers and Phone Services for 2023

Today's voice over IP (VoIP) solutions go far beyond simple phone calls. Modern, unified systems combine voice, video, chat, and other useful features. We've tested and rated the top contenders to help you choose the right one for your business.

Neil McAllister

Computer magazines and tech publications had a huge influence on my formative years, so when I was given the opportunity to work in tech journalism, I jumped at the chance. My career studying and writing about tech has now spanned more than two decades. Before PCMag , I spent time as a writer and editor at InfoWorld, and a few years as a news reporter for The Register , Europe's largest online tech publication. Throughout, I've strived to explain deep and complex topics to the broadest possible audience and, I hope, share some of the thrill and fascination I find in this field every day.

Intermedia Unite

Voice over IP (VoIP) is the modern evolution of business phone systems. Although desktop phones were once connected to analog PBX systems, today's VoIP solutions route digital calls via the internet, using platforms that are increasingly cloud-based. What's more, their functionality has broadened beyond voice to include video calling, text chat, SMS, and other features. Such diversified systems are often termed unified communications-as-a-service  (UCaaS).

Because VoIP is a mature market with lots of players, matching your business with the right system can be challenging. Some vendors provide general-purpose service, while others cater to customers with specialized needs, such as call centers. VoIP systems also offer varying degrees of integration with third-party software, such as CRM systems , to help automate business tasks. To help you understand your options, we sought out the leading solutions and put them through their paces. Below are the top-ranked offerings based on our tests. Read the mini-reviews and buyer's guide for tips on how to shop for the right VoIP system for your business.

Best Overall Business VoIP

Why we picked it.

With Unite, Intermedia offers an excellent VoIP communications system that scales from small to midsize businesses, up to enterprises. The company bundles free phones or related devices (cameras, headsets) with each subscribed seat, and its focus on integrating with third-party software makes it attractive for businesses that want to further support help desks and customer relationship management (CRM).

Who It's For

If your organization's looking for a general-purpose VoIP phone system, check out Intermedia Unite. Although it's not the cheapest business VoIP service in our roundup, it has enough flexibility and features to grow along with your business—enough for it to earn our Editors' Choice nod. It's also a good choice if you're looking for a VoIP system that has tight integrations with Microsoft Teams .

Best for Enterprise-Class Call Volumes

RingCentral has long impressed us with its business VoIP offerings. The latest iteration, dubbed RingCentral MVP, stands for "messaging, video, and phone," which is indicative of its move away from basic voice services toward a UCaaS approach. RingCentral has also proven itself reliable at high call volumes, something that many rival services struggle with when put under pressure. Its AI-backed transcription and call analysis features are particularly impressive. We're also appreciative of RingCentral's administration capabilities that give admins many options in an easy-to-navigate UI.

Much like Intermedia Unite, RingCentral MVP is a well-rounded platform that includes virtually every capability you'd want in a small to midsize business, which is why it also earns our Editors' Choice badge. For the price, though, we think RingCentral might be more attractive if you're expecting a relatively high call volume—even its mid-level pricing tiers place no caps on the number of users you can add to your plan.

Best for SMB Unified Messaging

8x8 has gone all-in on UCaaS, as reflected in its new (and somewhat cumbersome) branding. You'll get a unified experience for all your business calls and conferencing, and 8x8 rolls out new features and updates with a steady cadence. One example is the new Frontdesk feature, which debuted with the latest release. The tool makes it easier for small businesses to emulate the traditional receptionist's desk.

Although 8x8 lacks some of its competitors' more advanced features, we think it's still a plucky and fast-moving competitor in the small to midsize business VoIP space. Its focus on UCaaS demonstrates its forward-thinking approach, and should make it attractive to any organization that wants to make the most of what software-based calling and conferencing solutions offer. Its pricing might be more attractive to organizations with tight purse-strings that don't need all of the features found in our Editors' Choice winners.

Best for a Unified Communications Hub

Vonage is a VoIP pioneer in both the business and residential markets. Because of its deep roots in the industry, it's had a chance to build and refine many features that younger players are still trying to iron out. Vonage offers a good selection of third-party software integrations, notably including Salesforce, and it even offers support for companies that want to build bespoke applications that integrate with the platform.

If your organization absolutely must choose a mature and established provider for your VoIP service, look no further than Vonage. In that sense, Vonage might be the veritable IBM of SMB VoIP. That being said, if your requirements are not so strict, and you're looking for a VoIP option that might offer a better UI and be easier to self-manage, you might want to look closely at competing services.

Best for Softphone Users

We like Dialpad's dedication to its role as a software-based communications service. Although Dialpad supports hardware handsets, its real focus is its softphone, which the company regularly update. In fact, Dialpad says it ships new software updates every two weeks. Frequent updates aren't always a good thing, but we appreciate the company's insistence on constantly refining its offering. In particular, it's another entry in our roundup that's using artificial intelligence and machine learning to enhance its automatic call transcription capabilities.

Dialpad may not be able to go head-for-head with the largest competitors in the business VoIP field, but it still has many features. If you're interested in a technology-first vendor that strives to regularly innovate, particularly if you're planning to deploy softphones as your main clients, this low-cost solution might be right up your alley.

Best for Microsoft 365 Customers

Teams is Microsoft's widely used, all-in-one team collaboration platform, and Teams Phone is the official VoIP add-on for it. As you'd expect, then, it has excellent integrations not just with the other Teams components, but also Microsoft 365 . It doesn't quite measure up to our Editors' Choice picks, especially in regards to call center functionality. Still, it's hard to ignore the market leader in office productivity software when it comes to business communications.

Dedicated Microsoft shops might not even look further than Teams Phone when choosing a VoIP provider. Its UI is familiar, and it certainly doesn't hurt that Teams Phone customers receive support from Redmond, as they're used to. However, if you haven't already bought into the broader Teams platform for business collaboration, we have a hard time recommending that route if all you're looking for is a standalone VoIP system. 

Best for Legacy Handset Hardware

Ooma Office isn't as impressive overall as our Editors' Choice heavy-hitters, but it's still a solid choice for small to midsize businesses looking to quickly get a VoIP phone system up and running. It lacks fancy features, such as AI-based transcription and deep integrations with other software, but it's easy to use and manage. Its latest version adds welcome features—including video conferencing, SMS messaging, and contact syncing—that keep it in the running with competitors.

If you're looking for a modestly priced business VoIP system that won't overwhelm you with a huge catalog of features, Ooma Office might be a good choice. It uses a wizard-based approach to setup and management, which small IT departments will appreciate. If, on the other hand, you're looking for a feature-packed VoIP system, Ooma may disappoint. Still, if cost is a concern, Ooma is affordable and doesn't require a contract.

Best for Traditional PBX Capabilities

Mitel is a longtime player in business voice communications. As a result, its guiding principle for its MiCloud Connect VoIP system has been to replicate the features of traditional, on-premises PBX systems, such as making it easy to interconnect remote offices. Even when it's acting as a cloud service, it prefers to have a designated central office so that it can take advantage of a robust LAN. That means it can be harder to set up than some other business VoIP services, but it can offer real advantages in call quality.

Tiny shops might want to skip this one. Mitel's PBX-focused approach suggests it's better geared for midsize to large businesses. Similarly, highly distributed workforces might not gain as much benefit from MiCloud Connect as they could from other competitors. If, on the other hand, you're in the process of bringing employees back into a central office, and like the idea of leveraging a well-managed LAN for optimal call quality, Mitel's offering deserves a look.

Best for Customer Support, Call Centers

Freshdesk's VoIP offering is a little different than most of the others we've tested. Rather than targeting general business communications, it leans heavily toward supporting call centers, such as customer help desks. It integrates with various e-commerce, help desk, and CRM systems, including those provided by Freshdesk itself. It also offers admins an impressive collection of call metrics to help tune and manage a large-scale calling operation.

If you can't picture banks of constantly-ringing phones in your offices, and you don't do direct phone marketing, then Freshdesk Contact Center probably isn't for you. On the other hand, organizations with high call volumes and that are organized around functions like customer phone support will appreciate Freshdesk's focus on this area. You'll especially appreciate its call monitoring and management options that surpass the competitons' offerings to ensure a high-quality customer experience.

Best for Very Small Businesses

Compared to some of its competitors—and especially our heavy-hitting Editors' Choice picks—Line2's cloud business VoIP offering is so stripped down that it almost resembles a residential VoIP service. That said, Line2 is incredibly easy to get up and running, and you don't need to be a VoIP expert to use it. It lacks the features found in more integrated VoIP systems, such as video conferencing, but it provides well-designed softphone apps that provide basic telephony functions on desktop and mobile devices.

If all you want to do is provide business phone numbers to your employees, and don't want the hassle of a full-fledged VoIP system, check out Line2. Just about anyone can set it up, and you won't need to take time away from more important business tasks to manage it. Just be aware that once your organization starts to grow beyond its earliest stages, you'll probably find yourself looking for something that offers more features.

(Editors' Note: Line2 is owned by Ziff Davis, PCMag's parent company.)

What Is a VoIP Phone System?

Traditional landline phones are a form of analog telephony. VoIP, on the other hand, brings voice calling to the digital age. VoIP systems convert voice calls into network packets and transmit them over the internet or other IP-based networks. Most also include a bridge to traditional phone systems, so the people you call don't need to use VoIP themselves (nor do the people who call you). In addition, they typically emulate the functions of traditional PBX (private branch exchange) business phone systems, such as conference calling, call routing, and call monitoring.

How Much Does a Small Business VoIP System Cost?

Today's business VoIP systems are billed on a subscription basis. You'll be charged based on the number of users (phone extensions) you need, on either a monthly or yearly basis. Some vendors require you to commit to a specific term, while others don't. That said, you'll usually receive a discount by paying for a full year of service in advance. 

How much a given service costs per month can range widely. Most offer multiple pricing tiers based on factors like the feature package, the number of users you need to support, and how much you expect to use the service. Among the products we tested, pricing ranged from $15 per user per month at the low end, all the way up to $65 per user per month for an advanced, enterprise-grade product. Most small businesses can expect to pay about $20 per user per month.

What's the Advantage of a VoIP Phone System?

VoIP supplanted traditional PBX phone systems because it is less expensive but far more versatile. Even today's  residential VoIP  offerings include features far beyond those of conventional telephone systems. In addition to voice calling, most modern VoIP systems integrate other channels and features, including conference calls, call recording, mobile communications, video conferencing , team collaboration , and even social media, earning them the classification of unified communications-as-a-service ( UCaaS) —we'll discuss these in depth, below.

These days, most VoIP solutions have evolved into managed, cloud-based services—and with good reason. Moving to the cloud helps reduce costs, increase reliability, and lift the management burden off of your organization's staff, making cloud VoIP systems a clear winner.

How to Choose a Business VoIP System

Whether this is your first time switching to business VoIP or you're upgrading an existing system, the sheer number of options can be dizzying. It's important to remember that while we've evaluated the VoIP systems in this roundup based on factors like features, ease of use, and cost, the solution that's right for your business might not necessarily be the one that looks best on paper.

Your first order of business should be to consider just how your company plans—or needs—to use its phones. For example, if your goal is to upgrade an existing PBX, replacing it entirely might not be a viable option, if only because some parts of the system can't be easily changed over to softphones or even desktop VoIP handsets.

For example, suppose you're operating a heavy manufacturing environment with outdoor activities, such as a steel fabrication yard or a landscaping company. In that case, your rugged old outdoor phones may be just what you need there, and VoIP should only be deployed for office and remote workers.

Even for less extreme environments, you should think about the features you'll need—now and for the future—as well as the ones you don't. Without careful planning, it's easy to find yourself paying for capabilities you'll never use, not to mention unnecessary complexity that makes your phone system hard to manage.

One important step in this process is to sit down with all of the stakeholders who will be affected by your eventual decision. Naturally, this includes the IT staff and the data security folks, since your voice calls will now be data communications. However, department heads and employees who use the system to get work done should also have their say, especially those whose work drives revenue and engages customers. 

You don't want to hamstring anyone's activities by skimping on features, but you also don't want to overwhelm them with options they don't understand. The best VoIP system for your business will always be one that doesn't just meet your employees' needs; your workers should feel comfortable using it, too.

Softphones vs. Desk Phones

Traditional VoIP systems use dedicated VoIP phone equipment that sits on your desk and establishes calls via the Session Initiation Protocol (SIP). But VoIP has come a long way since these humble beginnings.

One of the most important innovations that modern VoIP systems bring to business communications is softphones . In a nutshell, a softphone is an app that replicates all of the features of a traditional, desktop business phone, and often much more. What you lose in plastic hardware, you gain in functionality, including video conferencing and text chat.

At their most basic, softphones let you use the speakers and microphone on your PC, laptop, or other devices to mimic the capabilities of a desktop phone. They also help convey many additional VoIP advantages. Their screen-based interfaces make it easier to switch between communications channels, even mid-call, and they also help the system integrate with other software, such as help desk and customer relationship management (CRM) systems.

Mobility adds an additional wrinkle. These days, most workers are accustomed to taking calls on the go. However, using a mobile phone's built-in calling features means you sacrifice VoIP's productivity-enhancing features, such as call monitoring, logging, transferring, and integrations with other apps. Many VoIP systems offer softphone apps that run on Android and iOS devices, and in some cases, these apps have full feature parity with their desktop versions. You'll want to investigate these options thoroughly if your staff includes a significant number of road warriors.

Networking Concerns and VoIP

Networking issues have always been a primary concern for any VoIP implementation. VoIP traffic is much more sensitive to network bumps and potholes than most general office traffic, such as web browsing. When a VoIP system is starved for bandwidth, that translates to garbled conversations, difficulty connecting, or dropped and lost calls.

Further complicating matters is the ad hoc design of many modern small-business networks. Chances are your small office network might consist of a few wireless routers , rather than dedicated Ethernet jacks at workers' desks, making monitoring and maintaining traffic quality more difficult.

In the wake of the global COVID-19 pandemic, at least some of your staff are almost certainly working from home , and there's a good chance that remote work will become a permanent part of modern employment, particularly for small to midsize businesses. Your internal IT staff will have little to no control over these staffers' home networks. 

Finally, the business VoIP systems in this roundup are all managed cloud services, rather than on-premises products that mimic a traditional PBX. We think that's a good thing: Cloud VoIP services can potentially offer greater reliability, easier management, and more features, all at a lower cost than first-generation VoIP systems. But they also increase your reliance on the public internet for the most basic distance communication needs.

The upshot of all this is that, unlike your local LAN, there's little your company can do to control networking conditions on the public internet. Managing your connectivity is almost entirely the province of your network provider—or multiple providers, if your workforce is geographically dispersed. Often, the best you can do is to hope for the best. Check out our roundup of the fastest internet service providers (ISP) to see which might be able to offer you the most bandwidth, and consider subsidizing high-speed connections for your remote workers.

Does VoIP Work With Alarm Systems?

Another issue worth considering is whether your business currently relies on alarm systems, such as perimeter alarms or motion detectors. Many of these connect to alarm monitoring services via traditional analog phone lines. You may be able to switch these lines to VoIP, but use caution. The digital codecs used to encode voice calls can interfere with electronic signaling devices, such as analog modems, fax machines, and alarm monitoring systems, which have different sound-quality requirements. Consult with your alarm company to see whether they keep a list of VoIP providers they have pre-vetted for this purpose.

Sustained power is another factor to consider. Analog phone lines operate on power provided by the telephone company, which is separate from the main energy grid. VoIP lines, on the other hand, need AC power, just like any other digital device. You'll want to make sure you have backup power available for your network routers, VoIP servers, and any other hardware your VoIP system requires, or you risk having your alarm monitoring service fail in the event of a power outage.

Going all-in with ucaas.

So far, we've talked about replacing traditional PBX systems with VoIP, but simply switching from analog voice to digital offers only marginal cost savings. Instead, the real value of modern VoIP comes from flexibility and integration features that only software-based communications can bring, which takes us to the fast-evolving field of unified communications-as-a-service (UCaaS).

The features offered in any particular UCaaS solution vary widely from vendor to vendor. Still, most include options for video conferencing, shared meeting and online collaboration tools, integrated faxing , and mobile VoIP integration. 

However, where UCaaS really starts to become a game-changer is when it lets your VoIP system integrate with other systems used within your business. For example, it might integrate with your CRM system, letting it recognize a customer's phone number or some other identifier and automatically pull up the customer's record for the technician or salesperson answering the call. It could even alert a manager to monitor the call if it's a critical client.

Other popular UCaaS integrations include help desk software and marketing automation tools. Some vendors even offer industry-specific features for certain verticals, such as healthcare. These backend software integrations explain the significant growth in the UCaaS market over the last several years. The concept is constantly evolving to include more communication and collaboration technologies.

What's Next for Business VoIP?

VoIP makes the most sense for the vast majority of SMBs, and not just because the costs are lower; VoIP is the only way to keep up with evolving communication trends. Software integration lies at the heart of VoIP and UCaaS, so you can't make a purchasing decision without thinking about the future. 

On the one hand, consider each vendor carefully to see what they've done over the last half-decade in product development and keeping up with VoIP and UCaaS trends. On the other hand, think about what you'll need in the next five years.

At PCMag, we've noticed three trends that almost all vendors mentioned as essential to their customers over the last year. That means they'll be crucial capabilities those vendors will want to add to their platforms in 2022:

Network Mobility. Although some VoIP services still offer mobile handsets, these devices seem to be on the downslope. After all, if talking while walking is your goal, why carry a clunky handset when you can speak on your smartphone? Seamless voice switchover based on geofencing is one approach. With it, your smartphone detects that it's inside your company's wireless network and seamlessly engages your VoIP client over Wi-Fi, not your cell service. You'll make and receive calls from your calling plan, as well as your business's VoIP service. This generally goes beyond simple calls and includes texts, voicemail-to-email, and collaborative online meetings.

5G Integration. However, a little further down the road is ubiquitous 5G . When that happens, several VoIP vendors will connect their services to 5G. Workers will then be able to access their business VoIP service wherever they are and across any device as long as it's 5G compatible. Although some vendors do this with current mobile technology, 4G's latency limits often deliver a sub-optimal experience. This applies to simple voice traffic, as well as video and collaboration. 5G is the first mobile service that promises the bandwidth necessary to make true mobile UC a reality.

Artificial intelligence (AI) . If your current phone system uses an automated menu to help route customer calls, or even if it extends its tendrils to your website's e-commerce features, expect UCaaS vendors to pitch you on artificial intelligence . In addition to the chatbot features we discussed earlier, your vendor can also use AI to detect security issues (see below). It can also work on the reporting and analysis side, so you'll have a much more granular understanding of call and network quality, call volume, and the apps most affected by your VoIP service.

These trends will likely become important selling points in most VoIP vendor-customer pitches over the next several years. Although that's great, be sure to fully understand what's being offered and how the vendor will deliver it. For example, is a 5G implementation truly standards-based, or are there some proprietary hardware or software components? How will new security measures affect overall voice performance, and does the vendor fully support the changing security requirements for industry regulations like HIPAA and Sox?

If all this seems like a lot to ponder, remember that it's well worth the effort. Just about anything you can picture a business needing from a phone or collaboration system can be delivered by a hosted VoIP solution at a more affordable price than purchasing and maintaining your own on-premises PBX. It's just a matter of selecting the right solution for your business.

The 5 Best Business VoIP Providers in 2023

5 out of 5 stars

With business VoIP services, you don't have to worry about limited numbers of physical phone lines.  VoIP services offer tons of perks that small business owners love . Some of these include being able to place VoIP calls from your desktop or cell phone using your VoIP phone number. What is especially great about it, is that when you call, your business phone number will show up on caller ID instead of your cell number or whatever you are using to make that call. This goes for incoming calls as well. They will dial the VoIP number and you can answer on whichever phone you want to use.

Bottom line: We searched through the market for the top services and found the 13 best VoIP providers out there—with RingCentral at the top offering price matching and a wide feature range at a low cost.  Ooma is also great for remote workers because of its ease of use and phone system flexibility.

For an easy-to-use business phone solution that also provides scalable services for your growing business at an affordable price, Ooma is a great option.

4 out of 5 stars

Best VoIP providers for small business

Ringcentral: best overall.

We love that RingCentral offers such a wide range of product features. And the plans are fairly affordable, with price matching available and a generous allotment of toll-free minutes. Just look out for a so-so customer service experience.

Data as of 2/15/23. Offers and availability may vary by location and are subject to change. *With annual billing

RingCentral offers a well-rounded work-from-home solution that includes integrated messaging, unlimited video conferencing, and cloud-hosted VoIP service right out of the box. The service includes a lot of features that other providers charge extra for (such as generous toll-free minutes). And small businesses don’t have to worry about whether they’re getting raked over the coals for their cloud-hosted VoIP service because RingCentral offers price matching on plans with less than 50 lines.

RingCentral VoIP plans

Data as of 2/15/23. Offers and availability may vary by location and are subject to change. *With annual billing for 100+ users **Price per user per month ***Retention period applies

Another thing we love about RingCentral is its reliability. RingCentral promises a 99.999% uptime, meaning both your in-house and remote employees can rely on your VoIP system to work whenever they need it. Plus, RingCentral plans include unlimited internet faxing, phone conferencing, and video conferencing for up to 200 participants. Video meetings can even last up to 24 hours—just in case.

Here are a few other features business owners are sure to love:

And if you ever experience trouble with your VoIP system, RingCentral’s customer service team is available 24/7 via online chat or via phone during standard business hours. Keep in mind, though, that usually only larger enterprises get US-based support—small businesses usually get outsourced to overseas customer service representatives. If that doesn’t work for you, though, RingCentral also offers ticket service, an extensive online knowledge base, and weekly webinars to answer common questions.

voip phone service for business

Ooma: Best VoIP service for remote work

If your business has transitioned to remote work, Ooma offers affordable services that are easy to use and can easily grow with your company. While some customers have complained about dropped calls, we think Ooma’s still the ideal VoIP service for businesses working remotely.

Data as of 2/15/23. Offers and availability may vary by location and are subject to change.

With its scalable solutions, Ooma is one of our favorite small-business phone services. But Ooma’s Office and Office Pro plans also stand out as some of the best VoIP phone service offerings for businesses with remote employees.

Ooma phone systems are flexible, so you can use your office phone while working at home, place and accept work calls on your cell phone, and even use the Ooma desktop app to place calls on your computer. And Ooma’s plans stay affordable even with an upper-tier plan.

Ooma VoIP plans

Ooma’s remote features can help your business stay up and running no matter where your employees are. For starters, Ooma’s mobile and desktop apps allow remote employees to make and receive unlimited calls within North America using your business number.

We also like Ooma’s Ring Groups feature, which lets you group extensions together in your phone system so they all ring simultaneously. Then it transfers the call to whichever employee answers first. This allows your customers to get through to a representative as quickly as possible and provides a backup in case one of your employees has to step away to deal with childcare or move the laundry along.

Businesses working remotely should keep in mind, though, that Ooma offers video conferencing only on the Ooma Office Pro and Pro Plus plans. Otherwise, you get a conference line that lets remote employees collaborate over the phone. That puts Ooma a pace behind some of the other providers on our list, but with providers like Nextiva currently offering their video collaboration tool to businesses for free, it shouldn’t be a major issue.

Nextiva: Best VoIP software for midsize businesses

If you operate more than one office or have employees scattered around your areas working from home, Nextiva is easy to scale without breaking your budget. However, this option may not be best for companies that need low-cost international calling features.

Nextiva is great for midsize businesses on a budget because it delivers an impressive balance of pricing and features. Nextiva’s mobile app and desktop app allow your employees to ditch the clunky office phones of the past, and the service’s online management platform makes it easy to juggle multiple lines—even when your employees are all working from different locations.

Nextiva VoIP plans

Nextiva service also provides a number of helpful features for businesses working from home. For starters, there’s the Nextiva app, which lets you use your business phone number to make calls remotely from your desktop or mobile devices. Nextiva’s team collaboration tool, Cospace, also lets your team collaborate via video chat, so you can keep everyone one the same page.

If you need a way to video chat with your team, but aren’t interested in a full-blown VoIP service, we have good news. Right now, Nextiva is offering video and team collaboration for an unlimited number of users—completely free. See the Nextiva website to learn more about their Video & Collaboration service.

Word to the wise, though: Nextiva’s pricing can be a little complex, so make sure you click around the website’s pricing page to find the accurate pricing for your business. The website lists the Essential plan at $18.95 per month, for example. But if you click the tiny question mark next to the price, you find out that price is only for prepaid 36-month contracts on plans with 20-99 users. If you’re a small business on a month-to-month plan, you’ll actually wind up paying $30.95 per month for the same package.

That being said, we think it’s impressive that none of Nextiva’s plans cost more than $45 per month—especially considering all the VoIP service features you get. And for businesses with remote employees, features like unlimited video conferencing (with a Professional plan or higher), screen sharing, and team messaging make it easier to get work done even when everyone’s physically distant.

Vonage: Best small business VoIP provider

Sure, Vonage has dealt with bad press and technical issues in the past. But these days, the service’s easy setup, impressive 99.999% uptime, and scalable business phone system options make it a top-notch VoIP choice for businesses with an eye toward growth.

Data as of 2/15/23. Offers and availability may vary by location and are subject to change. *Up to 99 users

As one of the earliest VoIP services on the market, Vonage is one of the most well-known PBX solutions currently available. And for good reason.

Vonage phone service can easily grow with your company, so you don’t have to worry about difficult transitions to new systems as your needs expand. Vonage integrates with everything from Salesforce to Slack, so you’re covered if your business ever outgrows its current customer relationship tools. And Vonage offers VoIP communications features that make the service easy to use even when you’re at home.

Vonage VoIP plans

Vonage plans offer great features for remote employees, including unlimited team messaging, unlimited calls, and unlimited business text messages on every plan. However, if video conferencing is important to your business, you’ll need to upgrade to the Premium plan.

We also like that Vonage offers 20 third-party integrations through the Vonage App Center, which is available even on the Mobile plan. This feature allows you to sync your VoIP phone system with select accounting, inventory, and CRM software so you can build out a completely interconnected business.

Furthermore, all Vonage customers get 24/7 customer support and IT solutions. Between that and all the other features included on Vonage’s basic phone system plans, it’s a great solution for small businesses that want advanced features at a budget price. And Vonage can definitely keep up when it’s time to upgrade your devices or add more lines, so your business can easily grow within your existing VoIP system.

8x8: Best budget buy

8x8’s claims to fame are its incredibly low pricing, cheap international calling rates, and crowdsourced customer service. This VoIP provider offers limited mobile access, but it’s a good pick for any business trying to save a buck without sacrificing quality.

Given all the economic uncertainty faced by small businesses today, choosing a low-cost VoIP phone service makes a lot of sense. 

Fortunately, 8x8 offers three simple, feature-loaded plans that can help you keep your expenses low while also getting all the VoIP features you need. 8x8 even offers integrations with third-party business apps like Salesforce, Zendesk, Netsuite, and Microsoft Dynamics. That way, your business can build out a complete enterprise resource planning solution that allows your inventory, accounting, point-of-sale, and customer service to work together seamlessly—all without having to shell out big money for it.

8x8 VoIP plans

Data as of 2/15/23. Offers and availability may vary by location and are subject to change. *When billed annually

All 8x8 plans include team messaging, HD video conferencing, and screen sharing, you you can easily keep all your remote team members engaged and collaborative. And contact centers that have transitioned to remote work can still enjoy features like omnichannel routing, which allows your employees to engage with customers via chat, social media, text, and phone—all in one platform.

And of course, you can’t ignore the fact that 8x8 offers full internet phone services that start at just $15 per month. The company’s introductory plan even offers an auto-attendant to help transfer calls to the appropriate extension without you needing to pay a receptionist to answer the phone—a feature other internet and phone providers don’t offer except on upper-tier plans. 

That being said, 8x8’s plan upgrades are not the cheapest on our list. But considering the number of features you get for the price, we think it’s a good value for most companies looking for a VoIP phone system that offers a lot of bang for your buck.

Grasshopper: best for mobile businesses.


While Grasshopper may suffer from minor audio quality and transcription problems, the service is a major contender for businesses that operate from multiple locations. It’s easy to set up and easy to use, and it includes toll-free vanity numbers.

Now more than ever, businesses are discovering that they don’t need their employees to work in an office environment to be successful. But Grasshopper is an especially great VoIP software for mobile businesses like food trucks and pop-up stores.

Like many other VoIP phone services, Grasshopper offers iOS and Android apps that allow you to make and receive business calls on your cell phone. But unlike the competition, it allows you to customize call forwarding rules for each phone extension on your plan. That way, each of your employees or business locations can manage calls in whatever way works best for them.

Grasshopper VoIP plans

Grasshopper is great for small businesses, so why didn’t we name it our top small-business phone service? To be honest, we think Grasshopper is a little expensive compared to other options on the table. Grasshopper plans start at $26 per month (assuming you sign up for annual billing), which is pretty pricey considering you get only one business phone number with up to three extensions.

Grasshopper also offers fewer unified communications features than other PBX solutions. You also have to provide your own devices. That’s not a big deal if your employees are all working from home and using their cell phones or desktop phones to place calls. But it may pose a problem if you need to upgrade your office’s old analog phones.

Oh, and Grasshopper only offers service to businesses in the US and Canada.

On the upside, though, Grasshopper offers the same features across all its plans. Unlike other business VoIP solutions, you don’t have to upgrade your plan just to get business texting (for example). That means your business can enjoy the same high-end VoIP phone system features as a large company, even if you have only a couple of lines.

Right now, Grasshopper is offering $75 off when you sign up for a 12-month prepaid plan. That way, you don’t have to break the bank to stay connected. See Grasshopper’s home page for more details.

Verizon VoIP: Most reliable

Verizon is definitely one of the most expensive VoIP options on our list. But given the company’s reputation for reliable mobile solutions and full-service fiber-optic connections, it may be worth the extra cost for some businesses (assuming you live in an area with Verizon’s fiber-optic options, of course).

Data as of 2/15/23. Offers and availability may vary by location and are subject to change. *With two-year contract

Verizon’s mobile solutions and ultra-fast fiber-optic internet connections (named Fios) have made the company the current gold standard when it comes to reliable telecommunications. And frankly, Verizon doesn’t disappoint when it comes to its bring-your-own-device (BYOD) VoIP service.

Verizon’s appeal ultimately comes down to its reliability. The telecommunications giant offers both fiber-optic and DSL connections nationwide. And say what you want about Verizon’s customer service—the company is one of the few internet and phone providers with a reputation for maintaining a state-of-the-art network with few to no dropped calls on its internet phone

Verizon VoIP plans

Unfortunately, that reliability doesn’t exactly come cheap. Verizon’s Business Digital Voice VoIP plan starts relatively high, and if you need more than 5 lines, you'll need to call them for additional information. Keep in mind that Verizon isn’t a budget choice for small businesses: it’s a reliability choice.

If you’re located in one of the 8 states (plus Washington, DC) that currently enjoy Verizon Fios service—which are mostly in the northeast—you’ll have access to one of the fastest internet connections available, which is perfect for VoIP. If your remote employees don’t have Verizon Fios internet or your business is in DSL-only country, the speed will be slower, but uptime is still guaranteed at 99.9%. Either internet option will support steady VoIP service, and if your business is more medium-sized than small, Verizon could add up to a better value in the long run (especially if you’re in Fios territory).

Since Verizon is a massive company, customer service ratings are in line with what you’d usually read in the comments section—meaning, people are far more motivated to complain than praise. Navigating Verizon’s bundling plans for businesses may be like a choose-your-own-adventure odyssey, but its support lines are segregated well, with separate contacts for small, medium, and larger businesses. Verizon also offers competitive SLAs (service level agreements) for quality and service and 24/7 VoIP phone services support via phone, email, and tickets.

Verizon Business Digital Voice isn’t necessarily budget friendly for a smaller business, but it should be attractive to medium and larger outfits that demand reliable uptime, or at least prefer an all-in-one telecom provider.

GoToConnect: Best feature-rich VoIP

Go To Connect Logo

GoToConnect offers all its features on every plan—the only difference is the number of users you get. That makes it easy to choose a feature-rich plan that’s easily customized to suit your business needs.

GoToConnect has nearly as many glowing reviews as the Radiohead discography, minus the pretentious lyricism. GoToConnect has established a positive industry reputation since its launch as Jive in 2006, thanks mostly to its interface simplicity, focus on small businesses, and large array of telephone features that are available to all pricing tiers.

GoToConnect VoIP plans

All these tiers deliver top-notch phone service features, which include the following perks:

In addition, GoToConnect plans deliver unlimited video conferencing for up to 250 participants. That makes company-wide meetings a lot easier while your employees are based from home. Plus, GoToConnect offers virtual international numbers in more than 50 countries—though you’ll have to pay a $19.99 setup fee, plus a charge per minute for the basic plan (you won't have to pay this in the upper tier plans if it's one of the 50 countries).

We also like that GoToConnect’s phone systems are easy to set up and come with US-based 24/7 phone, live chat, and email support (with specific help for small businesses, large businesses, government agencies, and education clients). Overall, it’s a simple and feature-loaded VoIP phone system that works for all kinds of businesses.

Best VoIP for Small Business FAQ

Since VoIP is a relatively new technology that differs from traditional copper-line telephone systems, there may be a bit of a learning curve before you dive into adopting it for your business. Here are a few elemental points to get started.

We believe RingCentral has the best VoIP due to it's fair pricing and wide range of features. It also offers price matching for plans with less than 50 lines—making it even more affordable. 

Yes, VoIP is good for small business. It is an easily scalable, cost-effective way to communicate.

What is a VoIP number?

A VoIP phone number is just like a regular telephone number, but it’s assigned to a user rather than a specific physical phone line.

When landline providers set up your telephone system, they map your new number to the physical copper connections that are hardwired into your home. But with VoIP phone systems, your number is assigned to your internet phone services account. That allows you to access your VoIP phone number (and make VoIP phone calls) from any device with an internet connection. That gives you the flexibility to use your VoIP phone number at home, in the office, or even from your smartphone.

What is number porting?

If you’ll be switching to a VoIP business system, will you want to keep your current phone number? Most VoIP services offer number porting, which lets you transfer—or port—your number to a new service. Check for number porting in a VoIP service’s features; some will apply it for free, while others may charge a one-time fee.

What is a SIP trunk?

A SIP (session initiation protocol) trunk carries voice, data, and video through a “trunk” that replaces copper telephone connections through the conventional PSTN (public switched telephone network), consolidating phone and internet service into a single digital line.

In plain English, SIP trunking allows you to physically disconnect from your phone company, opening the door for digital, internet-powered options (read: VoIP). And unlike hardwired telephone lines, digital lines allow you to scale your phone solutions as your business grows.

What is PBX?

A private branch exchange (PBX) is the closed telephone network within a business, which employees share for outbound, inbound, and interoffice phone calls. VoIP systems manage PBXs off-site through cloud PBX hosting, eliminating the need for costly (and space-hogging) on-premise equipment and maintenance.

What does BYOD stand for?

BYOD stands for  bring your own device . This term refers to employees conducting company business on personal laptops, tablets, and phones instead of on company-owned gear. Most VoIP companies offer BYOD features and solutions within their plans, either included or at additional cost. However, extra IT security layers and company guidelines for BYOD are on you.

What is power outage vulnerability?

As mentioned earlier, VoIP is entirely reliant on a high-speed internet connection—and is also entirely at the mercy of power outages. Telephone lines may be archaic, but they still work in a blackout—internet equipment and connections, not so much. If your business requires 24/7 uptime, make sure backup power sources are in place.

What is E911?

Unlike traditional telephone lines, VoIP numbers can’t be traced by 911 operators. This doesn’t mean you’d be helpless in case of a natural disaster or Sasquatch attack, however. Upon initial setup at a location, you simply need to enter your info manually through the system’s E911 (Enhanced 911) feature, which will attach a physical address to your VoIP number.

What basic features do you get with VoIP service?

Just as a smartphone can do more than a landline phone, a VoIP phone system for business can perform all the expected tasks of standard business phone plans and then some. They’re a great choice for small businesses that need full functionality, and the VoIP systems we’ve reviewed include most, if not all, of the following features:

Business owners report that VoIP keeps them connected during Covid-19

Just how crucial is Voice over Internet Protocol (VoIP) in 2023? According to small-business owners, very —and getting more and more important all the time.

That’s good news for the VoIP industry, which saw an 8.3% growth in 2020 amid stay-at-home orders and public health concerns. 1 That growth should continue, and multiple studies project that the VoIP industry will earn a US market revenue of at least USD $55 billion in 2025. 2

Based on a survey conducted by Business.org, predictions of the VoIP industry’s continued expansion are right on track. Per our survey results, over 64% of surveyed small businesses added VoIP services during the pandemic. And a full 85% of surveyed business owners said VoIP kept their teams more connected throughout 2020.

Our survey results

So apart from the fact that business owners in 2020 switched to or added VoIP in increasing numbers, what else did we learn? For one, more small-business owners with one business location added VoIP this year than businesses with multiple locations—61% of respondents had businesses with one location while 39% had businesses multiple locations.

Additionally, surveyed business owners value VoIP for more than its connectivity:

VoIP will remain crucial in the post-pandemic business world

VoIP is an essential part of an ever-increasing number of businesses. And with global 5G availability on the horizon, VoIP is perfectly positioned to become the next multi-billion-dollar industry.

The importance of having the right business phone system was demonstrated during the coronavirus pandemic. Companies with old systems struggled to answer calls when stay-at-home orders closed offices. Modern cloud-based phone services, by comparison, gave businesses big and small the flexibility to keep operating and even scale for growth while employees worked remotely.

Today’s business Voice over Internet Protocol (VoIP) systems can help companies improve collaboration and productivity. The options are vast, ranging from basic VoIP phone service to all-in-one platforms that provide phone, messaging, video conferencing, and even contact center solutions that integrate with your office software and CRM applications.

Choosing the best VoIP service for your business requires careful consideration, and our guide aims to help. Read on to explore how VoIP business phone systems work, what they cost, and how to ensure you get the best one for your organization.

Best Business Phone System of 2023


Intermedia is an excellent option for businesses wanting a unified communications phone system with cloud storage and Microsoft Exchange email mailboxes. You can mix and match packages and choose from three subscriptions with unlimited calling to U.S. and Canadian numbers, and video conferencing capabilities. Intermedia’s three packages are Essentials, Pro, and Enterprise. However, the entry-level plan lacks SMS texting, internet faxing, and voicemail transcription. Unite Pro and Enterprise include these features and offer additional functionality.

For instance, Unite Pro adds SugarCRM , Zoho CRM , and Zendesk integrations. It also has AI-driven meeting transcripts and insights. Enterprise subscriptions provide a Microsoft Exchange email box and integrate with Salesforce (Classic and Lightning), ServiceNow, and Microsoft Dynamics. Notably, all subscriptions have call recording and integrate with Microsoft Teams and Outlook, Google Workspace (formerly G-Suite), and Slack.

Nextiva provides a single user interface for communication and collaboration. It puts multi-channel interactions into threaded conversations, allowing you to see a client’s entire history, including phone calls, notes, emails, and text messages. There are three Nextiva plans: Essential, Professional, and Enterprise. All include 45-minute video meetings with up to 250 participants and a toll-free number with minutes.

The base plan doesn’t have call recording or SMS/MMS, but does come with team messaging and video conference recording.

In addition, Professional and Enterprise plans have integrations with CRMs , such as HubSpot , Salesforce , and SugarCRM .

Best Voice Intelligence Features


When paid annually, Dialpad’s entry-level plan is less expensive than others in our rating. Yet, it’s packed with features, including live speech coaching, automated post-call summaries, and real-time call transcriptions. The three subscriptions (Standard, Pro, and Enterprise) offer unlimited calling to the U.S. and Canada, file sharing, and five-hour video meetings with 10 participants.

If your staff lives or works outside of the U.S., Dialpad Pro and Enterprise provide local number support in more than 70 countries and allow international text messaging. These plans also integrate with HubSpot , Microsoft Teams, Slack, and Salesforce .

RingCentral  »


RingCentral provides four unified communications plans: Essentials, Standard, Premium, and Ultimate. The base subscription supports 20 or fewer users, but there isn’t a limit on other packages. All versions include unlimited calling to the U.S. and Canada, toll-free minutes (if you opt for a free 1-800 number), SMS, team messaging, and voicemail-to-text. However, you’ll need a mid- or upper-tier subscription for virtual fax, call recording, and video conferencing.

There are hundreds of integrations available, depending on your plan. For instance, Premium and Ultimate connect to CRMs , like Salesforce and HubSpot . RingCentral provides an array of collaboration and meeting tools, making it perfect for remote and hybrid teams. It features Team Huddle, an always-on video and chat meeting room where co-workers can drop in for spontaneous conversations. The whiteboard, breakout rooms, and presentation modes mimic in-person activities.

Solopreneurs and small teams with five or fewer phone users can sign up for 8x8 Express. The $15 per user monthly price tag doesn’t require a contract or annual billing. It’s also one of the most robust entry-level subscriptions, offering audio and video conferencing for up to 100 attendees, team messaging, and an auto-attendant.

Larger teams can mix and match X-Series plans for knowledge workers, supervisors, and contact center employees. For companies with international staff and clients, 8x8 has the edge over RingCentral. X2 offers unmetered calls to 14 countries, whereas X4, X6, X7, and X8 allow unlimited calls to 48 countries. Also, 8x8 has international phone numbers for branches outside of the U.S. or virtual numbers for U.S.-based organizations.

8x8 X-Series increases meeting capacity to 500 users, one of the highest limits on our Best VoIP Business Phone Systems of 2023 rating. Also, X2 and X4 allow users to livestream meetings via YouTube.

GoTo Connect  »

GoTo Connect

Best for Large Businesses


Like 8x8 , GoTo Connect offers two subscriptions with unlimited calling to more than 50 countries, making it a good choice for businesses with overseas clients. However, GoTo Connect doesn’t offer international phone numbers. Instead, you can choose a local or toll-free number. Standard and Premium subscriptions come with 1,000 and 5,000 toll-free minutes, whereas Basic users pay $0.03 per minute.

GoTo Connect integrates with Zoho CRM , Microsoft Teams, Salesforce , and more. All plans include the instant response feature, allowing users to send an automatic text message to first-time callers when they’re unable to answer the phone.

Vonage is a smart choice for remote or mobile-only users, as the starter plan has mobile and desktop apps. It also includes over 20 third-party integrations.

It requires a minimum of three users, so it’s not a great fit for solopreneurs. Although the entry-level Essentials plan costs more than other solutions on our Best VoIP Business Phone Systems of 2023 rating, it offers features typically locked behind mid- and upper-tier packages.

For instance, Aircall Essentials integrates with over 100 applications and provides application programming interface (API) access. Users can connect to HubSpot , Pipedrive, and Zendesk. However, you need the Professional or Custom package to connect to Salesforce .

Ooma has three business plans – Essentials, Pro, and Pro Plus – and three enterprise Unified Communications as a Service (UCaaS) solutions – Standard, Enhanced, and Call Center.

Ooma supports analog devices in its basic plans, while other companies in our rating put desk phone compatibility in higher-tier plans only. Ooma’s analog device support includes overhead paging systems and fax machines. Ooma is also the only company in our ratings to offer unlimited calling to Puerto Rico.

What is VoIP?

VoIP stands for voice over internet protocol. As the Federal Communications Commission explains, VoIP-based business phone systems route phone calls through your business's wired or Wi-Fi internet connection, instead of through traditional phone lines. While some users may experience a spotty connection, modern VoIP solutions generally offer pretty good call quality and reliability when a business has high-speed internet. You can usually make calls from VoIP phones or softphones to traditional phone lines and cell phones. Plus, you can forward calls to your landline or mobile phone if you’re away from the office.

It's possible to have on-premises servers for VoIP phone software, similar to a system called a PBX that handles traditional business landline calls. However, many VoIP systems are cloud-hosted, meaning that the VoIP provider's servers process your calls. That often makes it easier to connect to them from multiple locations, including through a cloud-based mobile app. This can be good for businesses with people who are frequently on the road or working from home.

VoIP phone systems often also include other services, such as video conferencing and internal company messaging. With cloud-based systems reliant on your phone company's servers and software, it can be important to pick a provider with the level of customer service that you want.

What Should I Look for in a VoIP Business Phone System?

A business VoIP phone system advertises a variety of features, including call recording, call forwarding, and video conferencing. Think about what your business needs to decide which basic and advanced features are important to you.

For instance, if you have employees working remotely, call forwarding to people's home phones and an auto-attendant letting callers be routed to the right person might be important features. You may also want internal messaging tools from your business VoIP service provider if your company doesn't already have one you're happy with. If you're frequently on the go, you might want voicemail-to-email features that let you quickly see what people are calling about and a mobile app that lets you access phone service features from your mobile device.

Before making a decision, make sure the companies you’re considering offer telephone features such as caller ID, call recording, three-way calling, auto-attendant, and video conferencing. Consider whether you'll need to frequently send and receive faxes, whether your employees will want a phone system that automatically integrates with a CRM , or whether you're mostly concerned with basic calling features and phone service.

Also consider a provider's customer service options, including whether the company offers 24/7 support and help with IP phone installation and configuration.

How Do I Choose the Best VoIP Business Phone System for my Business?

Start by clearly defining your business phone needs, says Sam Sansome, principal and VP of Operations, Sales, and Marketing at Aligned Technologies . He suggests asking some key questions:

1. How else might a VoIP system help my business?

Today’s VoIP services do more than send and receive calls over the internet. They offer advanced call management features; all-in-one platforms for voice, messaging, and video; and even may use AI to automate tasks, coach employees, and track issues and opportunities.

So instead of just replacing your existing phone system with a similar one, explore how modern VoIP features can improve the customer experience and make your company more accessible and responsive. “This is an opportunity for people to have some meaningful impact on the productivity of their workforce,” says Sansome.

2. What office and CRM software do I use?

Some VoIP phone services integrate with the software and CRM applications used by your business. Integrations are “huge” for boosting productivity, so you’ll want a system that works with your applications, says Sansome. An integrated app, for example, may let you pull up a customer profile, click to make a call, log call details into the CRM program, and attach a call recording or transcript, all without entering data manually. Some VoIP services enable custom integrations via APIs and webhooks.

3. How do employees and customers want to communicate?

It’s important to choose a VoIP solution that accommodates the needs of both, says Sansome. Do employees want desk phones? Would they prefer to use smartphones and computer apps? Do they want to team message and video meet with coworkers?

Customers increasingly prefer text and instant messaging. “Are you going to make it easy for them to do business the way they want to do business with you or are you just going to provide them with a phone number,” asks Sansome.

4. What are my basic phone system requirements?

How many employees, departments, and office locations do you need to support? Do you require toll-free phone numbers or specific call management features? What are your technical and customer service expectations?

“The great thing about these cloud systems is they are, by nature, extremely scalable,” says Sansome. Typically, it’s easy to add users, upgrade to next-tier plans, or switch providers by porting numbers.

5. Is my infrastructure adequate?

All cloud-hosted VoIP phone services require a high-speed internet connection. To ensure call quality and reliability, Sansome recommends you have two separate connections, plus run software-defined wide area networking, or SD-WAN, software. SD-WAN acts as a traffic director. It monitors the two connections and routes calls to the one performing best.

You also may need to buy IP desk phones for an on-premises phone system. Some VoIP services can adapt the analog phones you currently own.

You don't necessarily need any hardware for a VoIP-based phone system, because many provide support for mobile phone and desktop apps to make and receive calls. If you prefer to use more traditional office devices, many VoIP companies offer desk phones and conference room phones that you can use with their services, often preconfigured to quickly connect to their networks. You may be able to use third-party phones as well. If you have existing desk phones, you may need an adaptor to connect them to the VoIP network, particularly if they're traditional landline devices rather than digital phones.

Many business VoIP providers offer plug-and-play desk phones that are designed to operate with the provider's network as soon as you receive them. Such companies also often offer smartphones and desktop apps that can connect to their networks when you download them from the provider or your phone's app marketplace. If you're setting up an entire office worth of phones or adjusting existing devices to work with your new VoIP provider, you may want to see if the company can provide assistance over the phone or in person in setting up your new equipment.

VoIP service can be handy for remote employees. Often, business VoIP service will let you use the same devices at home and at work with minimal configuration, so you can use your business phone number to receive and make calls wherever you are. In addition, you frequently can use mobile devices or software-based desktop tools to connect to your VoIP system from any smartphone or computer. Many VoIP services also come with messaging and videoconferencing tools.

Securing VoIP phones can be more challenging than traditional landline phones, according to the Department of Homeland Security , but modern VoIP systems generally use encryption to keep your calls safe from eavesdroppers. VoIP companies, like other online companies, also use encrypted communications when you connect to their websites to prevent someone from accessing your account to steal phone time or access your payment credentials like credit card numbers.

Many VoIP providers also advertise compliance with particular privacy and security standards, including the U.S. Health Insurance Portability and Accountability Act (HIPAA) standards for safeguarding healthcare information, and Europe's General Data Protection Regulation (GDPR). Many also undergo audits according to protocols like SOC 2 and SOC 3, designed to ensure that companies have adequate safeguards to prevent data breaches. If you're required by regulators or corporate policy to do business with companies with particular security certifications, you can shop around for VoIP providers that have the necessary credentials.

It's also important to use the same safety measures you would with other internet technologies, like picking secure passwords and making sure your phones, computers, and other devices have the latest security updates and security software installed. That can help keep your VoIP accounts secure and reduce the risk of eavesdropping or unauthorized use.

The business phone systems in our rating can range from $15 to $100 per user per month. Lower-priced packages typically have limits on the number of users and offer fewer advanced features. The lower-priced plans are best for small businesses and solopreneurs.

With some VoIP services, it is possible to earn discounts for paying the annual free upfront, entering into a multi-year contract, or signing up more users. However, you may have additional fees for toll-free and international calls, premium support, hardware, and federal and state taxes and fees.

Not only can VoIP deliver on many more features, the software used is usually flexible enough to cover both working in an office as well as remote working.

Additionally, VoIP services don't simply offer phone calls. Because they are software-based, they commonly offer easy integration into other software apps, especially to help improve productivity (opens in new tab) . Additionally, not only are VoIP services relatively easy to set up and customize, the software commonly also provides analytics to help improve your phone service (opens in new tab) and KPI's.

Nextiva – best for new VoIP users (opens in new tab)

Nextiva's VoIP service solution (opens in new tab) is the right pick if you're new to VoIP technology and need a VoIP service that's user friendly without compromising on quality—just ask any of the 100,000 businesses that use Nextiva confidently already. Shop Nextiva's flexible pricing plans and range of features which rival competitor VoIP service providers with ease. 

What is VoIP and how does it work?

Let's start with the basics. VoIP, or Voice over Internet Protocol, is a technology that enables voice communications to be transmitted via an internet connection rather than through a traditional phone network. 

VoIP works in much the same way as a conventional phone system, but it’s usually much more affordable and easier to scale.

VoIP technology also comes with a suite of benefits that traditional phone systems don’t. For example, it enables you to make or receive calls from virtually any device, in any location, as long as you have an internet connection. Use your smartphone, tablet, computer, or even dedicated VoIP hardware to stay in touch at all times.

Many VoIP systems also come with several advanced features, such as simple call routing, advanced on-hold messages, and multiple phone numbers.

At the higher end of the spectrum, many VoIP packages are equipped with integrated tools, such as online fax, integrated email marketing, and video conferencing.

How much does VoIP cost?

The cost of a VoIP system can vary immensely. Numerous basic free solutions are available, and premium plans can range from a few dollars per year into the hundreds or even thousands per month for businesses with high-end requirements. 

Most VoIP service providers offer unlimited voice and video calling, along with unlimited SMS to numbers in specified parts of the world. Subscriptions are usually offered on a per-user basis, which means that you can expect to pay more if you need support for more team members. 

Some providers do offer all-in-one solutions that support a specified number of users for one price, but this payment model isn’t all that common. 

Expect to pay extra for advanced features, integrations with certain third-party platforms, and international calling options.

The benefits of VoIP

These are some of the most common features offered by VoIP providers. They usually come as standard, although some will only be included in more expensive packages.


Video and audio conferencing Many VoIP handsets come with screens and cameras built-in, so it’s possible to video conference right from a desk, without having to use a laptop. Audio conferencing can be a much more convenient option, especially when not every call participant has access to a camera-enabled phone.



Whether you work with a traditional phone system or VoIP, voicemail has become an essential part of our working lives. The great thing about VoIP voicemail is that you can access it anywhere and from any supported device, such as a cell phone or laptop. You need never miss an important call again.


Screen sharing Screen sharing is perfect for viewing (and controlling) a colleague’s computer for collaboration purposes and for helping a customer with a technical or sales issue. Integration is simple and the sharer doesn’t even need to download any additional software.


Home/mobile working Because VoIP works with the internet, your VoIP phone account can be accessed on any supported device: typically using an app on your phone, laptop, or tablet. This means you can make and receive calls to and from your VoIP number whether you’re working from home or visiting a client.


CRM integration CRM has become a vital tool for businesses for tracking interactions with customers and clients. VoIP CRM integration can help you manage customer relationships more efficiently through real-time call tracking, analyze customer behavior for marketing purposes, and provide a better customer experience.


Call monitoring With VoIP, voice (and fax) communications can be stored as digital data packets - this makes monitoring calls straightforward and efficient. Call monitoring keeps business standards high, enabling managers to monitor performance and compliance, reduce liability, and apply training accordingly.


Advanced call routing VoIP’s advanced call routing can direct inbound calls to any person or team in real-time. This means that you can easily communicate business hours, manage long wait times by offering an option to leave a voice message, and easily scale your call center as your team grows.


Call recording With VoIP you can record any call, making note-taking a thing of the past. Incoming and outgoing calls are stored on the cloud, meaning they can be accessed from anywhere. You don’t even need to record from the beginning to get the entire call - you can choose to keep a recording of the call at any point in the call.


On-hold music and messaging No one likes to be kept on hold in silence, so using the right on-hold music can help reassure people in line, and is an opportunity for you to promote offers and advise on services. On-hold music is usually offered by a VoIP provider, but you can also use third-party plug-ins to expand your musical options.

Reasons to buy

Reasons to avoid.

RingCentral MVP- formerly known as RingCentral Office - is a great all-rounder for businesses, regardless of industry. It's a cloud-based PBX platform that includes all the features that modern organizations have come to expect from their VoIP system: video software, collaboration tools (opens in new tab) , and even AI capabilities.

All the core features are included, such as an auto-attendant system, a company directory, call forwarding and handling, and multiple extensions. A 99.999% uptime SLA also means that businesses can have peace of mind that any disruptions to their communications network are going to be infrequent affairs.

There is also a range of pricing plans to choose from, starting with the Essentials plan for small to medium-sized businesses, and includes unlimited voice and video calling, a free local and toll-free number, and 1500 toll-free minutes but the limit of 20 users is unlikely to be enough for some firms.

Fortunately, RingCentral’s plans for larger businesses are where the solution really comes into its own. The Standard plan comes with no limits on user numbers, while the Premium offering also comes with automatic call recording, real-time analytics (opens in new tab) , and integrations with popular CRM tools (opens in new tab) like Salesforce, Zendesk, and more.

For organizations that need the most advanced VoIP solutions, the Ultimate package, also comes with device status reports and unlimited storage (opens in new tab) . Whatever plan businesses plump for, the scalability of RingCentral MVP is one of its most important benefits. With APIs available in the backend, this is a VoIP solution that can be scaled and customized accordingly into a full-scale unified communications solution as well as a cloud contact center (opens in new tab) .

If you’re considering cloud-based communication for your employees and customers, Nextiva certainly has many points in its favor, including flexible pricing plans and a range of features to match many of its rivals.

You can make unlimited calls to any phone in the US or Canada, and its real-time presence feature also allows you to see which of your contacts is currently available, while the call queue allows you to handle calls during busy times. Video conferencing is available with all plans, and Nextiva allows you to share screens and files during your conferences. You can also use Nextiva’s video function to livestream virtual events and  webinars (opens in new tab) . 

Other features include that voicemail messages can be delivered directly to your email inbox, and the software also gives you the ability to record your outgoing voicemail message. You can also send and receive an unlimited number of text messages, and you can send and receive unlimited faxes.

Nextiva's system has clearly been designed with usability and functionality in mind. By dividing its tools on the basis of communication, sales, and service, the company allows you to find the features you need as soon as you log in.

There are also various integrations available, such as for Outlook and Google Contacts, as well as for Salesforce, Hubspot, and Zendesk on the Professional plan.

One of the biggest selling points could lie in the option for a free trial. If you’re still undecided, it might be worth signing up for the trial to see if Nextiva is the right solution for your organization.

Software has changed the nature of telephone communications in many offices and this is particularly evident when using Dialpad. The VoIP solution is cost-effective and well-designed and is particularly suited to businesses that have workflows favorable to using softphones – software applications that are installed on internet-connected devices in order to make phone calls.

The company’s VoIP offering, actually called Dialpad Talk, uses cloud calling and AI to boost employee productivity (opens in new tab) and flexibility. Members of staff can work from anywhere and use any device for their business conversations, and AI-powered voice intelligence can be used to automating note-taking and detect customer sentiments during a call.

User setup is straightforward as Dialpad comes with one central administrator portal that makes it easy to add new users, assign them phone numbers, connect them with office suites (opens in new tab) like Google Workspace and Microsoft 365, and establish their permissions. The whole process should only take a few minutes and either a desktop interface or smartphone app can be used to manage user profiles day-to-day.

While remote working has certainly become more common of late, Dialpad remains compatible with many desk-based phones, and the company has also partnered with Jabra and Poly to integrate functionality with a number of headsets.

Price-wise, Dialpad Talk is extremely competitive, and there is an option to include integration with the identity management platform (opens in new tab) Okta.

4. 8x8 eXperience Communications Platform

Perhaps the first thing to notice about the 8x8 eXperience Communications Platform is its price tag. For an enterprise-standard VoIP service, its base offering is very affordable, which is ideal for any organization that feels like it is currently spending too much on its communication tools.

The 8x8 Express Plan comes with unlimited video conferencing (opens in new tab) , chat, calling, and SMS messages across the US and Canada and a bespoke app to manage all your business communications. As a sweetener, the plan also comes with a one-month free trial, plus three months of Wix Unlimited so small businesses can get started with their website building (opens in new tab) plans as well.

For businesses that need more features than those on offer with the Express plan, the X Series X2 plan provides unlimited calling within 14 countries, video and audio conferencing, SMS, MMS and Teams (opens in new tab) chat functionality, and various enterprise integrations, including Google Workspace, Microsoft 365, Outlook, NetSuite, Salesforce and ZenDesk.

The X Series X4 plan, meanwhile, adds unlimited calling within 47 countries, call quality reporting, and supervisor analytics. Additional plans are designed to cater for voice-focused contact centers and multichannel associates.

It is worth noting that the 8x8 eXperience Communications Platform does not offer a bargain basement service – and higher-level plans can come at a significant cost. Aside from the great affordability provided by 8x8's more basic plans, all the company's solutions also make great collaboration tools. A universal team messaging application allows businesses to collaborate internally as well as with clients and vendors and includes extensive interoperability with third–party solutions.

5. GoToConnect

With all of the VoIP solutions featured in this guide, there is a multitude of different features on offer, depending on the particular pricing plan that businesses decide to go for. What makes GoToConnect so impressive is the sheer number of features available, with the platform offering businesses more than 100 calling, collaboration, and mobile features and tools, as well as several video conferencing services.

All of the general features, including custom call routing, team-based call distribution, as well as time-based and geolocation routing, are included, and customers also have access to personal meeting rooms.

Advertising itself as a UCaaS solution, businesses don’t need to install any new equipment and GoToConnect will handle all maintenance and upgrades. That being said, the company does recommend that customers have a business-standard router (opens in new tab) , an Ethernet switch capable of Quality of Service, and a firewall (opens in new tab) configured to allow access to HTTP, HTTPS, and UDP traffic on their network.

Interestingly, unlike most VoIP service providers, GoToConnect does not charge businesses more for additional features. Instead, the company’s pricing plan varies based on how many employees a business has. Prices range from $29.95 per user, per month for customers with between one and four users, to as little as $19.95 per user, per month for businesses with between 50 and 99 users. All pricing plans come with access to the majority of GoToConnect’s tools, and bespoke pricing plans are available for businesses with more than 100 members of staff.

Among the available features are Cloud PBX, custom hold music, call management, advanced ring strategies, and one-click screen sharing. Of course, more features do mean a greater potential for things to go wrong, but GoToConnect also offers extensive email and call support should any issues arise.

6. Ooma Office

Affordably priced and with a couple of different plans to choose from, Ooma Office is a great choice for smaller firms or businesses that have a sizable number of remote workers. 

The basic plan comes with a mobile app, a virtual receptionist, call-forwarding functionality, and a host of other features. Ooma Office Pro adds video conferencing tools, voicemail transcription, and a number of other useful business features.

The offering is particularly useful for companies with remote workers, with both the mobile and desktop apps allowing workers to make and receive unlimited calls within the US using their business number. 

Another particularly handy feature is Ring Groups, which allows organizations to group extensions together so they all ring simultaneously. The call is then simply transferred to whichever employee answers first. 

Although the fact that video conferencing only comes with the more expensive pro plan may disappoint some businesses, Ooma Office still represents a great choice for firms that may not need the flashiest VoIP solution. 

Read our full Ooma Office review (opens in new tab) .

1-VoIP offers both residential and business VoIP solutions, with its business offering proving particularly useful for companies on a budget. Companies gain access to HD call quality and more than 40 features across 1-VoIP’s metered plan. With this plan, customers only pay for what they use, facing an additional charge of 2 cents per minute for any calls made.

All features are included with each business plan, with extension-to-extension calling, digital call forwarding, and cell phone redirection available at no extra cost. Other useful features include the use of an auto attendant to make sure callers are redirected to the correct department, and custom pre-recorded announcements that can be adapted for each particular recipient. 

One of the most useful aspects of the 1-VoIP solution is its integration with the third-party anti-spam service Nomorobo. So far, this solution has been used by organizations to block more than 2 billion automated spam calls. The service is flexible, allowing companies to toggle the feature on and off, and businesses can report new spam numbers to the service for review. The service is also continuously monitored so calls from essential services like schools and pharmacies are always permitted. 

A few frustrating aspects of the 1-VoIP service have been pointed out by users, particularly in terms of the setup and configuration. Finding the right settings for international calling can be challenging, for example, and there’s not much in the way of integration with CRM solutions (opens in new tab) . Nevertheless, 1-VoIP is a good choice for businesses that want a fairly standard VoIP solution that will prevent telemarketers from pestering their employees.

Read our full 1-VoIP review (opens in new tab) .

8. AT&T Business

Telecoms giant AT&T may be one of the older players in the communication space but that hasn’t stopped it from adopting the most up-to-date developments in the VoIP market. In particular, what makes AT&T Business so unique is the way that it integrates with legacy systems. AT&T Collaborate supports prebuilt integration with approximately 30 external services, including Microsoft Outlook, Microsoft 365, and various Salesforce offerings, and existing analog office phones can continue to be used.

Although new registrations are no longer being taken for AT&T Collaborate, AT&T [email protected] is a flexible cloud-based solution delivering voice, fax, and text messaging options, as well as audio and video conferencing features. The solution is cloud-based and comes with three pricing plans.

The Standard Edition includes unlimited internet faxing, 1000 toll-free minutes per month, and allows unlimited user numbers. The Premium Edition also comes with Salesforce integration and 200 HD video seats. Prices for the Enterprise Edition vary but all customers will receive 10,000 toll-free minutes a month.

While AT&T does allow businesses to use their own hardware for the [email protected] service, providing it is compatible, the company will not be able to provide help desk support. Instructions will be provided on how to configure the equipment but that is unlikely to completely prevent difficulties from arising, so it’s a good idea for businesses to employ experts during the installation process.

Once installation and configuration are out of the way, however, AT&T Business is simplicity personified. Each employee is given their own unique extension and direct-dial number for voice, fax, and text messaging.

9. Grasshopper

Acquired by remote access solutions provider LogMeIn in 2018, Grasshopper delivers a great VoIP service for smaller firms, particularly those that may not have the financial resources to invest in additional hardware. With Grasshopper, businesses simply gain access to a PBX software instance that connects extensions to existing phone numbers. Businesses only need a functioning phone number, existing handsets (which includes cell phones), and a reliable internet connection. 

But while the requirements for Grasshopper are slight, the number of features on offer are also somewhat limited. There is no analytics here, nor the kind of advanced features needed to support call centers or VoIP desktop phones. Customers do gain access to an unlimited number of business calls and texts, call forwarding options, and 24/7 support but beyond that, there’s not much to say about the Grasshopper solution.

Fortunately, the pricing is very favorable, with a Solo-tier for one number and three extensions. The Partner tier, on the other hand, offers three numbers and six extensions, whole the Small Business tier comes with up to five numbers and an unlimited number of extensions. Unlike most VoIP providers, Grasshopper’s prices aren’t charged on a per-user basis. These are all-in monthly costs, which means small businesses could face a significantly smaller bill. 

Aside from the price, the ease of setup is another bonus of the Grasshopper solution, with users simply selecting their service level and choosing their numbers before the service is ready to go. There’s also a  desktop, iOS, and Android app for easy management of Grasshopper’s features.

10. Microsoft Teams Phone

Microsoft’s many digital solutions are already commonplace in offices all over the world and the company now has a cloud telephony service to add to its portfolio. Microsoft Teams Phone lets organizations make calls from any device to anywhere in the world, leveraging the company’s cloud services to ensure high levels of reliability and good audio quality.

In terms of pricing, Microsoft Teams Phone works out to be very affordable - particularly if subscribers are already paying for Microsoft 365. It includes a cloud-based phone system with advanced features such as call transfer, multi-level auto attendants, and call queues, as well as 24/7 customer support. 

Perhaps the most attractive feature of Microsoft Teams Phone is the way that it integrates seamlessly with Microsoft Teams. Since the onset of the COVID-19 pandemic, Teams has become increasingly important to businesses and many will no doubt appreciate the ease with which Microsoft Teams Phone connects to the platform. Setup is quick and it is easy to view upcoming Teams meetings and connect to discussions via your VoIP handset. 

The major drawback for users of Microsoft Teams Phone is that it comes with a user limit of 300, which makes the service suitable for small to medium-sized businesses (SMB) only. Nevertheless, if that’s not an issue, then Microsoft Teams Phone represents a great option, particularly for firms that already rely on a number of other Microsoft solutions.

Frequently asked question about VoIP

Looking for more information about VoIP? Our FAQ will help you understand the benefits of VoIP solutions for businesses of all sizes.

What equipment do I need for VoIP?

The only equipment you need for a VoIP system is a strong internet connection and a device that can connect to the internet. 

Most service providers offer some sort of mobile and/or desktop app which you can download and use to manage incoming and outgoing calls and messages. On top of this, many VoIP platforms feature a powerful web interface, enabling users to log in from any device with an internet connection. 

However, many businesses opt to add extra VoIP hardware. Specialized phone systems, headsets, and even things like PC handsets are available to streamline business workflows and maximize the efficiency of your VoIP. 

Speak with your VoIP service provider to find out more about the available hardware options. 

Is VoIP free?

There are numerous free VoIP solutions available, but most of these are targeted at personal users rather than businesses, and they tend to come with quite limited features. Popular examples of free VoIP services include messaging apps such as WhatsApp, Skype, Viber, and more.

Many people go with free VoIP apps because they are simple, easy to download and set up, and in general, more than adequate for basic personal use. However, they tend to be a little limited when it comes to advanced features for business, which is why we often recommend a premium solution.

One major drawback with free VoIP apps is that everyone has to be using the same application. You can’t use WhatsApp to call Skype or vice versa, for example. And in most cases, a paid solution is required if you want to call phone numbers directly.

In terms of advanced business features, most free solutions lack even basic tools such as call recording, simple data collection, and on-hold messages, which will likely be a major concern for many corporate users.

So, while free VoIP options are available, business users will generally be much better serviced by a premium solution.

How does a VoIP phone number work?

For all practical purposes, a VoIP phone number is identical to a traditional landline or cell phone number. It enables you to call any landline or mobile number, send SMS messages, and access other advanced features. 

The main difference between a VoIP number and a traditional phone number is that a VoIP number isn’t linked to a specific phone line or SIM card. Rather, it’s linked to a user and can be accessed from virtually any device with an internet connection. 

What are the disadvantages of VoIP?

Despite its rapid growth as a business phone technology, VoIP has its disadvantages over traditional phone systems. With a good VoIP setup, these will generally be minor, but it’s still important to be aware of them. 

For one, all VoIP systems require a strong internet connection. If your connection is slow or unstable, your phone system will likely suffer. You may have trouble making or receiving calls, which can impact general business processes. 

Additionally, you need to ensure your connection has low latency. This basically means that there shouldn’t be major delays in either transmitting or receiving VoIP data, or else your system will be hindered. 

Another minor consideration is that your VoIP devices will need to have a reliable power source. Many traditional phones don’t require consistent mains power, and most others consume very small amounts of energy. However, VoIP devices can’t be used if there’s a power outage, which means that you may need to consider installing some form of backup supply.  

Finally, not all VoIP systems are secure. Ensure you’re using a reliable service provider to reduce the risk of hacking, viruses, and serious data loss.

What are the advantages of VoIP?

Although it has its disadvantages, the advantages of using a VoIP system usually outweigh these. 

The cost savings associated with setting up and using a new VoIP system, compared to a traditional business phone network, are probably top of the list. Infrastructure costs are significantly lower, as are recurring service costs.

Another clear advantage is the flexibility that VoIP offers. Let’s say, for example, that you’ve had to leave the office early for some reason. If you have your VoIP app installed on your smartphone, you can continue to make and receive important calls as long as you have an internet connection. 

Similarly, you will be able to log in to your VoIP interface from your personal computer if required. Team members can also work remotely without relying on hardwired phone systems, which significantly improves business flexibility. 

Furthermore, VoIP systems are highly scalable, which makes them a great option for fast-growing companies. It’s extremely easy to add new users without having to purchase expensive hardware, which is a feature that many businesses will find attractive. 

Finally, most VoIP systems come with significantly more advanced features than traditional phone systems. Things like call forwarding and automated attendants are extremely easy to set up. You’ll also often have access to advanced video conferencing and messaging tools, and you’ll be able to select local phone numbers for virtually anywhere in the world. 

How do you call a VoIP number?

To call a VoIP number, follow the same steps as you would to call a landline or mobile number. VoIP phone systems function in practically the same way as traditional systems, enabling users to send and receive calls and SMS messages. 

One thing to note here is the country and area codes of VoIP numbers. Firstly, just because an individual or company has a number with a certain area code doesn’t mean that they live or operate there. In fact, many businesses have local numbers across the world to make it easier for clients to contact them. 

On top of this, you’ll need to be mindful if you’re calling a VoIP number from a landline or cell phone. Otherwise, you may end up placing an international call which could become very costly. 

Can I text a VoIP number?

Yes, you can text a VoIP number. 

Texting them is exactly the same as texting a normal cell phone. The VoIP user will receive your texts via their user interface, on a smartphone, tablet, PC, or specialized hardware. 

VoIP technical terms explained

Bandwidth In a VoIP context, your system’s bandwidth refers to the amount of data that can be transferred at any given time. It’s usually measured in bits per second and provides important insights into the capability of your network. Larger networks with more users will naturally require a higher bandwidth. 

Codec Codec is a technical term that refers to the software used to compress and decompress VoIP data. Different systems use different VoIP codecs, and these play a large role in determining your system’s bandwidth and audio quality. 

DSL DSL, or Digital Subscriber Line, refers to one of the most popular types of VoIP installation. It uses existing copper telephone lines to establish a broadband internet connection, transmitting audio and video data through a DSL router or modem. 

IP Internet Protocol (IP) telephony refers to the various technologies that form the basis of modern VoIP solutions. These are used to transmit voice, fax, and other data from a VoIP device to the traditional phone network and vice versa. 

IVR IVR, or Interactive Voice Response, refers to software that delivers automatic audio information to callers. With this, you can set up keypad-controlled menus, enabling callers to connect with the most appropriate team members with a minimum amount of fuss. 

Latency The term latency is often used interchangeably with lag. In layman’s terms, it refers to the time it takes for data to transmit. Slow internet connections generally have high latency, which decreases as your connection gets faster. 

PBX A PBX, or Private Branch Exchange, is designed to manage a company or organization’s internal phone systems. In a VoIP context, you will often see the acronym IP PBX, which essentially manages extensions, fax systems, and every other aspect of your phone system. 

RTP Real-Time Transfer Protocol (RTP) is designed to enable the streamlined transmission of audio and video data. Its main purpose is to ensure all data has a temporal reference, making sure audio and video transmissions are fully synchronized at all times. 

SIP Trunking Session Initiation Protocol (SIP) trunking is used to transfer voice and other data over an internet connection. In simple terms, it enables VoIP users to connect with traditional phone users, providing a bridge between the two different systems. 

Softphone The term softphone is used to describe any app or other program that enables you to use a mobile device or computer as a phone system. Usually, softphone interfaces come with everything you need to manage incoming and outgoing calls and messages. 

VoIP VoIP, or Voice over Internet Protocol, is the base technology underlying internet phone systems. With it, users can make and receive calls from virtually any device with an internet connection. VoIP systems are generally much more affordable than traditional phone systems, which makes them attractive to businesses across the world. 

Which type of VoIP service is best for you?

When deciding which of the best VoIP providers to use, first consider what actual needs you have. For example, someone simply wanting to talk to a handful of people on a casual basis may find a budget option is the most cost-effective while providing all of the necessary tools that would be required. However, if you're planning to use a VoIP provider for professional or business purposes, especially with a large number of people and on a regular basis, then you will probably want to look to the higher-end options for the more advanced tools that are included.

How we tested the best VoIP providers

To test for the best VoIP providers we first set up an account with the relevant software platform, whether as a download or as an online service. We then tested the service with VoIP and video calling, as well as the range of administration tools available. The aim was to see how user-friendly its features were, and also how easy it was to get to grips with any advanced options.

In this guide, we’ll compare each VoIP service based on features, pricing, customer service and more to help you decide which is best for your needs and budget.

per user, per month

Although 8×8 isn’t the least expensive choice, it is the best cheap VoIP phone service provider for small businesses because of how well-rounded it is. The plans are affordable, ranging from $15 to $44 per user, per month, and you can save even more if you opt for annual pricing (up to 25%).

As is the case with most VoIP phone services, 8×8 offers unlimited domestic calling on all plans and features such as an auto attendant and voice mail. But 8×8 sets itself apart with its unlimited international calling. While you’ll have to choose the mid- or high-tier plan, both offer considerable savings over the competition because you won’t pay a per-minute rate for calls or texts.

The lowest-priced plan from 8×8 is good as is, but if you’re looking for SMS texting and call center supervisor features you’ll have to pay for an add-on or upgrade to one of the pricier plans. There are some limitations with 8×8’s service: call and video recordings are only stored in the cloud for a limited time period, and interactive voice response (IVR) is a costly add-on for all eligible plans.

Who should use it:

Whether you’re running a micro-operation or an enterprise, 8×8 offers high-quality VoIP service with advanced features at an affordable price for all plans.

Best for AI Tools

Dialpad offers three VoIP phone service plans for businesses that scale in its advanced features, but the pricing remains relatively affordable for small companies. Plans range in cost from $23 to $35 per user, per month (the Enterprise plan is by quote only and requires a 100-user minimum). You can choose to pay annually and save $8 to $10 per user, per month.

What stands out about Dialpad are its artificial intelligence-powered features. All plans get automatic call summaries, real-time call and video meeting transcriptions, voice mail transcriptions and real-time analytics. Some of these features aren’t even offered by the top-ranked VoIP phone services and typically these AI-assisted features would only be available at the highest price.

Although Dialpad is affordable and offers a handful of incomparable features, it has limitations. For example, phone support is only available 24 hours per day on weekdays for the low-priced plans (24/7 on all other plans). Plus, you’ll have to pay a per-minute rate for international calls and texts.

Small businesses that want affordable AI features to help them track conversations and meetings with clients and colleagues.

Best for Small Teams

Grasshopper ditched the standard per-user plan pricing of most VoIP phone services and chose to charge flat monthly fees instead. You’ll pay $29 to $89 per month for its service (or $26 to $80 per month if you pay yearly). It’s an affordable way to get started with VoIP for your small business.

Rather than hiding features behind a higher-priced plan, Grasshopper gives you all of its available features at all levels. The limiting factors here are the number of extensions and phone numbers you get. The lowest-priced plan gives you one phone number with three extensions; the mid-level tier gives you three phone numbers with six extensions; the highest-priced plan gives you five phone numbers and unlimited extensions.

Grasshopper offers standard features for a VoIP service, including texting, call forwarding, auto attendant, virtual fax and visual voice mail. What’s missing are advanced tools, such as video meetings, call center manager controls and integrations with work operating systems (OS) such as Google Workspace or Slack. If your business is growing slowly and you simply need to add a phone number here and there, you can do that for $10 per month for each extra number.

Grasshopper is an ideal cheap VoIP phone service for small teams that don’t need advanced features or multiple phone numbers.

Best for Medical Professionals

$11.99 to $29.99

Phone.com not only offers some of the lowest monthly per-user rates in the VoIP industry, it includes some unique features. Plans cost $14.99, $19.99 and $29.99 per user, per month—but you can save 20% by paying annually instead. It’s important to note that not all plans include unlimited calls; the entry-level plan offers only 300 minutes for the whole account (you’ll pay for any overages). Other plans include unlimited minutes.

The most unique aspect of Phone.com is that all plans include HIPAA-compliant voice calls, so communication is protected for your business and your clients. Video calls on Plus and Pro plans are also HIPAA-compliant. All plans also include SMS texting, voice mail, transcription, video calls, auto attendant and faxing.

Although Phone.com is one of the best cheap VoIP phone service providers for small businesses, there are multiple add-ons that could raise your price considerably. A global number costs $4.99 to $14.99 per month; additional phone numbers are $4.99 per month (you only get one per account for the low-priced plan or one per user on the higher tiers); call recording is $7.99 per month for the low- and mid-tier plans; and inbound faxing costs $4.99 per month.

Phone.com doesn’t offer a free trial, but there is a 30-day money-back guarantee so you can try it out before you commit.

Specifically, Phone.com is a great choice for medical professionals that require HIPAA compliance for all communications. The HIPAA-compliant technology is available for all plans for voice and for video meetings on the higher-priced plans.

Best for Lowest Monthly Rate

Google Voice used to be the go-to VoIP solution for a second personal or professional phone number—you could use the Google phone number to make and receive calls from your personal smartphone to maintain privacy. Things have changed and now Google Voice is only intended for business use, but Google is keeping the cost very low. Pricing ranges from $6 to $18 per user, per month.

Obviously, Google Voice integrates with the Google Workspace suite of tools, so Voice works with Google Hangouts chat, Google Meet, its video conferencing software , Gmail and Google Calendar. It’s easy to use Google Voice and it includes the most common features of VoIP phone service providers.

Domestic calls are unlimited to and from the U.S. and Canada. You’ll also get unlimited SMS texting in the U.S. There’s voice mail transcription, call forwarding and 24/7 support. A multilevel auto attendant is available, but only for the $20 and $30 per-user monthly plans. Advanced reporting is only for those on the highest tier. Also, you’re limited to ten users on the lowest-priced plan—you’ll have to upgrade if you need to add more users.

For the absolute cheapest VoIP phone service, choose Google Voice. The $10 per-user monthly rate is the lowest you can find for the features you get.

Choosing the best cheap VoIP phone service provider for small businesses starts with pricing, obviously. However, the cheapest service doesn’t always equate to the most value for your dollar. Forbes Advisor compared several cheap VoIP apps to find the most affordable ones that also offer more than standard VoIP phone features.

We looked at general features, such as unlimited domestic calling and SMS texts. Then we considered advanced features, including unlimited international calling and call recording. We also took into account unique offerings, such as HIPAA compliance and AI-powered features.

Customer ratings are important to consider as well. We sifted through several customer reviews, compared rankings on top review sites and contacted customer support ourselves to help reach our final rating for each VoIP service provider.

What is the least expensive VoIP service?

Free VoIP phone services would be the least expensive and they may be enough for ultrasmall businesses that are just getting started. However, if you need advanced features, consider Google Voice for the lowest price or 8×8 for the best inexpensive VoIP phone service for small businesses.

Can a landline call a VoIP phone?

The short answer is yes. More specifically, a landline call to a VoIP phone requires data packet switching. VoIP sends the data via the internet, while traditional landline phone calls use the public switched telephone network (PSTN) to send data. Both systems are reliable and advancements in technology make it possible for landlines and VoIP phones to send and receive calls to and from each other.

Is VoIP cheaper than regular phones?

It can be. Most small businesses require internet in their offices and VoIP takes advantage of this technology so you can make and receive phone calls over that internet connection. VoIP phone services tend to be more affordable because of this. Hardware is also more affordable—you don’t even need to invest in desk phones—you can use VoIP softphones with a headset to make calls from your PC or use VoIP on your smartphone via an app.

What’s the best VoIP service for businesses?

This will vary according to the business’s unique needs, as every company has a different number of users to plan for and features they need to help things run smoothly. Most of the companies in this article made our list of the best business VoIP services overall, but the winner was too expensive to include in this guide.

What features do VoIP services offer?

The most basic VoIP services include unlimited calling and voice mail, while more advanced features include visual voice mail, call forwarding, toll-free numbers and CRM integrations.

Are VoIP phones secure?

In general, using a VoIP phone, including a VoIP cellphone is very secure. However, there are steps that you can take to increase the security levels even more. These include verifying that your VoIP provider offers an encrypted connection, implementing a session initiation protocol (SIP)-capable firewall that filters all incoming calls for any content that puts your system at risk, and having your information technology (IT) staff create a virtual local area network (VLAN) for all of your internal calls to take place, keeping them from being put at risk from outside sources. Make sure that your staff remains diligent when using their VoIP phones so that they can avoid risks like voice phishing, also known as vishing.
