VoIP stands for voice over internet protocol and is a combination of technologies that transmit different types of media, such as voice calls, over the internet in digitized form instead of using typical analog phones, such as a landline.
In the business world, the advantage of using VoIP systems is that they can be combined with other technology and software for an integrated and feature-rich experience. Some pluses include using advanced call routing, built-in office hours, gathering call analytics, and the ability to make/receive business calls from any device.

To curate this list of the best VoIP services for small business, we first identified the most important factors for most small business owners to consider. We then applied these metrics to VoIP and collated the data with customer feedback, data from consumer watchdog organizations, and other VoIP reviews to come up with the best VoIP systems available:
VoIP phone service for business providers can use different pricing models, such as a flat monthly rate or per-user pricing. Either can be split into packages with different features, call/texting limits, etc. There may also be additional costs, such as setup fees, add-on services or features, and different calling rates, depending on the type of call or region.
Features & Specifics
Scalability (multi-locale) & Add-ons
Conversely, per-user priced systems are usually the most scalable in terms of bandwidth, usage limits, and the number of lines that can ultimately be supported. Features also play a determining role in what size of businesses a specific platform is suitable for.
Business Tools Integration
Some businesses rely heavily on enterprise applications for their day-to-day operation. A PBX system that can integrate with your business ecosystem can allow smoother integration with your overall operations and allow you to get more out of your phone system.
Set up & Ease of Use
A professional VoIP solution is meant to help support your business, not hinder it. Any downtime can be critical to a business, so the speed with which you can set up the system and train your employees is vital.
One of the main advantages of a VoIP platform is that it allows for voice over IP mobile business phone calls using native apps. In this case, the user experience of these applications/softphones are equally important.
Reliability & Sound Quality
One concern regarding VoIP systems is the quality of calls as it is subject to internet speeds and bandwidth. From personal experience and customer feedback, we looked at the quality of the service as well as for any guarantees when it comes to reliability.
Security & Compliance
A cloud-based PBX/VoIP service usually means you don’t have to worry about security and compliance. With that in mind, we looked at the security track record of the relevant VoIP companies as well as any past incidents.
With any ongoing service, customer support is critical to avoid excessive downtime, issues with onboarding and training, and to have a solid experience using a platform. Availability and responsiveness are vital.
Ooma is a VoIP phone service for home use, small businesses, and even enterprises. They not only provide physical devices from third parties such as Yealink but also their own Ooma-branded devices.
Ooma’s range of Telo products for home users can also be used for individuals or entrepreneurs working from home thanks to their capabilities and low prices. However, the main aim of these devices is convenience because it cross-connects communication abilities for your smartphone and home phone wirelessly. The Telo and Telo Air only cost a once-off fee without any recurring taxes or fees whereas the Telo 4G costs $11.99 per month. However, the latter can be used to make cellular calls and is operational even if your home internet goes down.
There are also two voice over IP for business packages: Ooma Office and Ooma Pro. Both plans are priced per month per user with an upfront $29.95 setup fee. Both come with 35 business features, including a virtual receptionist, call forwarding/transfer, virtual extensions, and more. While Office only comes with a softphone app for mobile, Pro can be used on a desktop as well. Office only costs $19.95 per user per month while Pro costs $24.95. For the extra cost, you get call recording, enhanced call blocking, voicemail transcription, and higher usage limits. A free phone number is included (business, vanity, or repeating).
Enterprise-scale solutions are available but are produced on a quote-by-quote basis. Unfortunately, the 30-day refund policy only covers your hardware and not your monthly fees. Business customers can look forward to 24/7 phone and live chat support, while phone support for home users is limited.
Verizon is a household name in the telecom industry, and it should come as no surprise that it makes it on this list of the best internet phone service options. Verizon is mostly focussed on solutions for business clients with plans and products suitable for everything from small, family business (1-500 employees) to large-scale corporate clients (500+ employees). They also go beyond just providing a VoIP number and offer products with internet, TV, networking, collaboration, and even security solutions.
Understanding that businesses usually require highly scalable solutions that grow with them, Verizon’s plans are incredibly flexible. Their unlimited business phone plans come with limitless calls, texts, data, and video streaming, while the flexible business plans allow you to independently customize your smartphone and tablet data limits with unlimited calls and texts.
All solutions come with softphone software for mobile devices, desktops, and even Chrome.
Flexible plan data limits range from 100 MB to 10 GB with charges of between $65 to $105 per month depending on how much you need. Business unlimited plans cost a monthly fee that also depends on the kind of device you want to use. The Unlimited and Plus plans also come with higher speeds for more enterprise-scale suitability:
Most customers will have to do with phone support limited to weekdays and office hours, although 24/7 support is available to higher-tier customers. That said, Verizon has vast support resources, including specific teams handling queries for businesses with different plans and sizes.
Vonage has plans and products to offer both home users and small-to-medium businesses worldwide. In fact, they are a rare type of voice-over-IP phone provider that offers its platform in just about every country. Vonage started out as a residential VoIP number provider but has successfully branched out into the business world.
Home users can look forward to straightforward and affordable packages all of which have the option for month-to-month plans as well as a 30-day money-back guarantee. North America and World plan customers also enjoy a $10 per month discount for the first 6 months if they opt for annual payments. The plans are:
These plans are perfect for residential VoIP use or those that regularly make overseas calls.
Vonage’s business packages are priced on a quote-by-quote basis depending on your country, the scale you want to operate at, and what package you need. There are over 50 business communications features spread across 4 packages with higher tiers unlocking more features. The business solution also features a powerful API for customization as well as Salesforce integration.
Vonage can offer excellent reliability with a 99.999% uptime. Customer support is also on hand 24/7 over live chat, while email and phone support have limited hours.
One of the main reasons why VoIPo finds itself on this list is because it is one of the cheapest VoIP providers. Perhaps, they took a queue from their parent company, HostGator. It’s hard to imagine finding a $6.21 a month deal anywhere else for a VoIP client that includes a physical phone, over 40 call management features, as well as unlimited U.S. calls. VoIPo is primarily aimed at, and suitable for, a home audience or small businesses that require a single-digit number of phone lines.
You also get 60 minutes of free international calls which is a nice little bonus. The only catch attached to the low price is that you have to commit for 2 years while the month-to-month rate is more than double at $15. That being said, you will be protected by a 30-day 100% satisfaction guarantee.
For a no-equipment option, you can go for either of the cloud-hosted VoIP packages. At $36 per year or $4.95 per month, they are even more affordable. However, limits are lower at 500 minutes a month for a normal U.S. number and 100 for a toll-free one.
Basics like transferring your current number, call forwarding, softphone access, three-way calling, and texting come with all the plans. VoIPo lacks some more advanced features, though, including video calling or voice conferencing. If you need a more all-encompassing solution for your business, VoIPo does offer cloud-based phone systems starting at $20 a month. VoIPo doesn’t limit their email support times, although you shouldn’t expect 24/7, lightning-fast responses. Phone and live chat support are available during office hours.
Depending on the exact communication needs of your business, 8×8 can be much more than a VoIP provider. They offer a host of other solutions, which include all-in-one business communication suites, video conferencing, training/onboarding, and even contact center-specific capabilities. The platform also features a mature developer API as well as superb access to integrations with third-party business tools, such as Microsoft Teams, 1CRM, Slack, Freshdesk, and more.
However, their business phone product, mostly for small to medium businesses, is still their cornerstone. On top of VoIP capabilities, it also comes with a cloud PBX system to really integrate your VoIP communications into your business. You can also expect top-notch service with training, support, and professional services included with each package.
Because of its advanced PBX capabilities that empower individual employees, 8×8 is priced on a per-system basis and is costlier than most other services on this list. There are three solutions to choose from, all coming with unlimited calls, texts, and faxes:
Overall, 8×8 delivers a modern, full-featured cloud VoIP business phone solution. The only downside is that their live chat and phone support are limited to office hours Monday-Friday.
Phone.com sits somewhere between a more basic business phone-only cloud-based VoIP service and the more advanced platforms with CRM capabilities. Developers can make use of an API to extend and integrate with their business systems and there are built-in integrations for Zapier, PayPal, and more. Phone.com also comes with over 50+ business phone features that cover the essentials as well as some extras. However, it doesn’t offer as many advanced business tools.
Phone.com provides two different ways to pay for your business online phone service. With a metered plan, you have limited call minutes and texts but can have an unlimited number of extensions. With an unmetered plan, you get unlimited minutes and texts while you will be billed per extension – with discounts for buying in bulk:
All plans only come with one free imported, local, or toll-free number. As you can see, very few features are price-locked which is great for those with a tight budget. Unfortunately, only the Base plan comes with a money-back guarantee.
Phone.com proudly boasts about their 24/7 U.S.-based bilingual support offered over multiple communication channels. Their support might be exceptional but be aware that you may need to pay a little extra for certain features, such as a live receptionist, voicemail-to-email transcription, etc.
Spectrum is a full-featured cloud VoIP UCaaS platform which means it provides a full suite of business communication tools and features. On top of calls, SpectrumVoIP can also be used for internal or external texting, voicemail, faxing, video conferencing, and collaboration. The web portal also comes with in-depth analytics and management features. Although it has been a weak spot in the past, SpectrumVoIP is also moving more towards providing mobile office tools.
Aptly named, SpectrumVoIP offers a single, all-inclusive plan called the “Everything Plan”. It comes with all 50+ features, including an auto attendant, call recording, unlimited rollover lines, a web portal, and a mobile office. It also comes with unlimited usage for calls, texts, and internet faxes. As you might expect, SpectrumVoIP is slightly more expensive than your average VoIP provider at $24.95 per month. However, this does mean that you won’t have to worry about any extra costs. You’ll even be provided with a physical, next-gen hosted VoIP device with each plan if you go for a yearly package.
You can also expect full-service support with free on-site installations as well as 24/7 technical support staff based in the U.S. Even if you want to DIY problem solve, SpectrumVoIP provides excellent documentation as well as video tutorials. Add to that the fact that each customer gets a dedicated project and coordination manager to ensure their VoIP technology is ticking over smoothly, and you’ve got yourself a business partner, not just a tool.
Formerly Jive, GoToConnect is a leading business VoIP communications platform that focuses on providing flexibility as well as scalability. With different suites of products, you’ll be able to find a suitable solution for anything from a single line of communication to a complete unified communications system and everything in between. Similarly, the user-based pricing and organization of various suites of features can scale from small businesses to enterprise-grade organizations.
Although GoToConnect has a huge selection of communication packages to choose from, they’ve managed to keep it simple – if you know what you’re looking for. Their various suites of products have self-explanatory names, such as GoToConnect, GoToMeeting, GoToRoom, GoToWebinar, and GoToTraining and are aimed at different aspects of business communications.
GoToConnect is focussed on providing the best VoIP solution for business phone communications. While it focuses on business call features, you also get access to video conferencing with up to 25 participants, a fully functional cloud PBX, and call center capabilities.
Pricing is determined according to five tiers, starting at 1-5 users at $29.95 per user per month up to 50-100 users at $19.95 per user per month. However, enterprises with 100+ users can request a custom solution on a quote-by-quote basis. Most other suites are priced per organizer with different tiers unlocking more features.
GoToConnect is also an exceptionally reliable provider with a 99.99% SLA-backed uptime guarantee as well as 24/7 customer support across multiple channels. Although feedback was mixed when they operated as Jive, it seems to be unanimously positive since their rebranding.
Like GoToConnect, Mitel actually offers a huge array of individual business communication suites focusing on individual business needs. However, Mitel features an even larger catalog of products, and business owners should do some browsing to make sure they settle on the best option for their needs.
For this review, we’ll focus on Mitel’s Business VoIP product line, MiCloud Connect, voted as one of the Best Business Tools of 2019 by Newsweek. This suite brings together all of Mitel’s business communication and collaboration tools into a single hassle-free solution. This omnichannel platform can be used to communicate with customers via phone, email, chat, SMS, and social media.
Mitel’s business communication packages are split according to the scale you operate at as well as what type of features you need. All plans come with all the fundamental cloud PBX system features, including softphones, G Suite and Outlook integration, and unlimited minutes:
You can now also try out Mitel 3 months for free, which is an excellent vote of confidence.
Impressively, Mitel operates out of offices in all major regions across the globe, allowing for region-specific 24/7 customer support across multiple communication channels. They also provide excellent onboarding support as well as a wealth of video and other resources.
Intermedia Unite is a provider of cloud communications solutions for businesses on every scale. Its suite of products and services include just about every aspect of a modern business’ IT needs, going further than most VoIP phone providers.
Intermedia Unite is a unified communication and collaboration platform for SMBs. It brings together a cloud-based PBX system, video conferencing, file management, as well as chat and screen sharing communications into a single package. There are two plans to choose from, both coming with unlimited calling, 5 concurrent endpoints, 90+ PBX features (including team chat and SMS), and 10 GB cloud storage:
You also get one local phone number included, with additional numbers available at extra cost. It goes without saying that all other essentials, such as voicemail, call routing, extensions, etc. are all standard. Intermedia is definitely not the cheapest business VoIP, especially considering that it’s priced per user but it’s certainly one of the top VoIP providers in terms of sheer capabilities and overall service.
You might not be at all surprised to know that Intermedia Unite also provides 24/7 customer support. Interestingly, its support staff is JD Power certified – attesting to the quality and reliability of the services they provide. Similarly, Intermedia is so confident in its reliability that they will give you a portion of your fees back if you experience downtime greater than 0.001%.
While certain features, standards, and metrics apply universally, the fact is that all businesses don’t fit the same mold. We picked the above best VoIP for small business providers based on the most critical factors. However, it’s crucial that you understand your needs and how you want a VoIP system to improve the way you do business before you choose:
What are your primary goals for wanting a VoIP phone system? Customer support? Internal voice communications for employees? Marketing? Client communication? Call center? Knowing this will help you pick the best VoIP based on what features are available, what it costs, what business applications it integrates with, and how it scales across multiple users.
Business size & Scalability
Not all VoIP providers cater to all business sizes. Most providers offer predefined packages for growing small businesses with custom solutions for enterprises. Although all-in flat monthly pricing may look attractive, the VoIP technology underneath and the usage limitations might not be suitable for larger organizations. The number of lines, call/usage limits, users, pricing, and features are all scalability concerns.
If you are already relying on enterprise applications, such as Microsoft Dynamics/Teams, Salesforce, Zapier, or other collaboration tools such as Slack, you might want to look at a cloud PBX system that integrates with this third-party software which will help you get the most out of both. A developer API will also allow you to come up with custom integrations. Two additional concerns are:
In any for-profit (or even non-profit) venture, your budget is of critical importance. Most feature-rich and enterprise-grade systems are priced per user per month, while smaller-scale solutions with a flat monthly rate usually have user limits imposed. Regardless, it’s crucial that you look at what you get for the price as missing out on certain features may cost you more in the long run. With a hosted VoIP system, there may also be additional costs, such as set up fees, physical device costs, and call rates to consider.
Ease of Use & Accessibility
First of all, you don’t want a new system to take a long time to be set up and integrated into your business. Onboarding should also be easy for your employees, and it’s preferable that a provider offers onboarding support services. One of the main advantages of VoIP/cloud PBX technologies is the ability to access business call features from anywhere, using a computer, mobile device, or browser-based application. If this is included, the ease of use and accessibility of the VoIP software is also important.
Tech Support Availability
Few people think of support until they run into an issue that they can’t solve. If competent, helpful, and responsive tech support is not readily available, it might bring your business to a standstill. Depending on your own in-house technical resources, customer support should be one of your main considerations. If you operate internationally, or around the clock, 24/7 support is even more critical. Also, make sure it’s using the communication channels you prefer (phone, chat, ticket, video, etc.).
There are multiple benefits to using a voice over IP phone service instead of a traditional landline, especially for small businesses. The first is that VoIP phones don’t necessarily require any actual phones or phone lines and can operate from existing devices, such as computers, mobile phones, or even tablets using softphone technology.
Because calls are transmitted via the internet, you can use your existing internet connection to make or receive VoIP calls, SMSs, faxes, or voicemails. This often leads to savings in call minutes as many cloud-served voice over IP (VoIP) providers offer unlimited minutes that are tied to bandwidth usage and not typical analog phone minutes.
This also means you can use the same platform or software for a unified communications solution that includes live chat, video conferencing, webinars, and training. More advanced systems can also include CRM capabilities or integrate with third-party applications to integrate seamlessly with your business.
As you can see, picking the best business VoIP for your small business venture is not a decision that should be taken lightly, and there is no one-shoe-fits-all solution.
We’ve brought together our choice for the best VoIP companies for small business based on considerations that are important for any organization, such as pricing, usability, scalability, integration, support, features, and the overall quality of the service.
Small businesses especially have a lot to gain from using a hosted VoIP as it can reduce the overhead costs when commpared to using traditional phone devices and associated call rates. The best VoIP systems also provide extra features, business opportunities, and greater flexibility for your business.
Now, it’s up to you to cross-reference that with your individual needs to identify the best VoIP platform for a modern and professional business phone solution for your company.
Voice over internet protocol (VoIP) is a technology protocol whereby voice information is digitized and transmitted via the internet, instead of traditional analog phone lines.
The short answer is the same as a conventional phone number: to make and receive calls, texts, voicemail, and even faxes. The difference is that a VoIP phone number is a digital phone system which means it can be used and managed on a computer or mobile device via supporting software.
One clear reason to opt for a hosted VoIP system is if you want to integrate your phone system with other enterprise applications. However, digital phone systems also provide the flexibility to make and receive calls online from anywhere (as long as you have an internet connection) and can reduce the costs of investing in physical phone devices.
There is no single best VoIP for every small business. Instead, different VoIP systems may have different advantages, depending on their features, integrations, scalability, and pricing for different businesses. Our methodology, best business VoIP choices, and the buyer’s guide will help you identify the best VoIP for your business.
The most common pricing model is per user/line per month. You may also be charged a flat monthly rate for a set number of lines/users. Some features may also be locked, with higher-tier packages unlocking more advanced tools. Setup fees or call rates may also apply. While some providers will give you devices, such as adapters or VoIP phones for free, you may need to buy them separately as well.
