1. 8×8 Express
Best VoIP phone system for sole traders and small businesses
8×8’s X Series VoIP packages have been specifically designed with small businesses, startups, and sole traders in mind, and none more so than the 8×8 Express package. Including features like unlimited calling within the US and Canada, an auto-attendant, video conferencing, and integration with your G Suite and Office 365 tools, this package turns the cell phones or laptops you (and your team, if you have one) already use into a professional business VoIP system. That said, it is also compatible with a range of plug-in-and-play desk phones.
How much does 8×8 Express cost?
8×8 Express costs $12 per user, per month, which is incredibly affordable. If you wanted to upgrade to a more advanced plan for a less mobile, more office-based workforce, 8×8's X Series starts at $24 per user, per month on the X2 plan.
- 8x8 Express is one of the cheapest business VoIP phone systems we've come across
- You'll get a three-month subscription to Wix included, so you can get your website up and running
- 8x8 Express is designed for more mobile workers, and so isn't intended to be used with desk phones
Best VoIP softphone technology
Similarly to 8×8 Express, GoToConnect’s sophisticated app turns a mobile phone, tablet, or PC into a full blown business VoIP phone system. While a touch more expensive than 8×8, you do gain unlimited access to all of GoTo’s features for calling and UC capabilities, including video conferencing, instant messaging, extension dialling, call hold and unhold, call history, SMS, location-based call rules, and an intuitive drag-and-drop call flow editor that enables you to easily customize your call routing. And perhaps the biggest reason to invest? You can make international calls to 52 countries for free.
How much does GoToConnect cost?
GoTo charges the following for its business VoIP phone system:
|Plan||Price (per user, per month)|
|Basic||Starting at $24|
|Standard||Starting at $29|
|Premium||Starting at $39|
- Boasts over 100 business VoIP phone system features
- Free domestic calls, plus free calls to over 50 countries
- Super intuitive call flow editor makes call route customization simple
- Its cheapest package is more expensive than most systems' cheapest packages
Best customizable VoIP phone system
FreePBX is an example of open source VoIP software, which means that your developers are free to go in and customize bits of code to tailor the VoIP system to your exact needs. The base software, which is free, comes with features including audio and video conferencing support, voicemail to email, Interactive Voice Response (IVR), unlimited extensions, and more – and you can customize the system with add-ons like call center features, softphone capabilities, and many others. Plus, you'll be able to integrate FreePBX with an unlimited number of other systems, including your CRM software, as long as they have open APIs (think of them as open-ended puzzle pieces, ready to be connected to other platforms).
How much does FreePBX cost?
FreePBX is a little unconventional. Its software is free initially, but you'll have to pay for the feature add-ons you need, and for the system to be hosted on a server for you (unless you want to buy PBX hardware instead). Most system suppliers bundle these costs into one per user, per month fee, but the fact that you can pick and choose what you get with FreePBX means you'll pay for things separately.
Firstly, you'll need to chose from one of FreePBX's hosting packages. Costs here start at $19.99 per month for one to 10 users, and end at $209.99 per month for over 1,000 users.
You'll also need to choose your business VoIP phone system features. Many of these are free, while others come in the form of add-ons that you'll need to pay for. One option is to go for one of FreePBX's add-on bundles, for which it charges a yearly license fee, rather than a monthly subscription charge. Interestingly, FreePBX gives you the option of buying a license that'll last for 25 years – and will net you some pretty excellent savings if you do use the system for several years:
|Bundle||Price for a one-year license||Price for a 25-year license|
|Call Center Bundle||$999||$1,999|
- You can create a truly bespoke system that fits your needs exactly
- Could work out cheaper than other systems – your monthly hosting fee covers the whole business, instead of being charged per user
- You'll need someone with some technical know-how to set up the system
- You'll need to pay extra for customer support from FreePBX
4. Vonage Business Communications
Best VoIP phone system for remote working
Vonage Business Communications' super affordable ‘Mobile' plan is designed for remote workers, with unlimited calls, SMS, and team messaging to keep everyone in touch from their own devices. Upgrading to the ‘Premium' plan, which won't break the bank either, will get you video conferencing for up to 100 people with Vonage Meetings (video meetings, as we've learned, are instrumental when it comes to working from home success), as well as integration with CRM platforms, the ability to use the system on IP desk phones, a multi-level auto-attendant to give your callers a professional experience, and many more important features.
How much does Vonage Business Communications cost?
Vonage charges the following prices for its business VoIP phone system:
|Plan||Price (per user, per month)|
|Mobile||Starting at $14.99|
|Premium||Starting at $24.99|
|Advanced||Starting at $34.99|
- Vonage's plans are all pretty affordable
- You'll get access to the Vonage App Center, from which you can integrate a variety of tools
- The cheapest plan doesn't enable you to use desk phones (but that may not matter if you're remote)
- Some key call features, including ring groups and call recording, are only available on the most expensive plan
5. RingCentral Contact Center
Best VoIP phone system for contact centers
RingCentral’s contact center software features all the tools you need to run effective customer communications. Omni-channel customer routing means agents can use phone, email, and SMS to speak to customers. RingCentral also provides you with agent management tools to promote peak performance, and the ability to generate in-depth reports and customer surveys.
How much does RingCentral Contact Center cost?
RingCentral's system for contact centers is available in three price plans: ‘Basic', ‘Advanced', and ‘Ultimate'. Prices are tailored to your business, though, so you'll need to get in touch with RingCentral for a bespoke quote to learn how much it'll cost for you.
RingCentral Contact Center integrates with RingCentral Office, the company's business VoIP phone system. You'll need to subscribe to Office in order to use Contact Center. RingCentral Office's prices are as follows:
|Plan||Price (per user, per month)|
|Essentials||Starting at $19.99|
|Standard||Starting at $27.99|
|Premium||Starting at $34.99|
|Ultimate||Starting at $49.99|
- Enables you to communicate with customers in the ways they prefer
- Comes with excellent features for optimizing your workforce
- RingCentral Contact Center is an add-on you'll need to pay more for (but that's true of most call center systems)
- Prices aren't shared publicly, so we don't know how much you can expect to pay
6. Ooma Enterprise
Best VoIP phone system for enterprise businesses
Starting at just $27.99 per user, per month, Ooma Enterprise is one of the most affordable business VoIP phone system packages for large companies that we've come across. It includes video meetings and softphone apps for all your employees, and can be customized to meet the varying needs of your different teams.

Ooma can also supply you with dedicated desk phones, conference phones, and fax machines.
How much does Ooma Office cost?
Ooma's business VoIP phone system is available in three price plans:
|Plan||Price (per user, per month)|
|Ooma Enterprise Call Center||$49.99|
If you're looking for a simpler solution, Ooma provides another system – Ooma Office – which starts at $19.95 per user, per month.
- Ooma charges for its most advanced package (Ooma Enterprise) what many other systems charge for their basic or middling packages
- Comes with an excellent range of call features to boost your team's efficiency and mobility
- Ooma doesn't state how many participants can take part in each video call, so we can't advise on whether your teams will be limited
The Benefits of a VoIP Phone System
So, why invest in a VoIP phone system for your business? There are plenty of reasons to do so, but these are the most impactful:
Because VoIP systems make and take phone calls over the internet, those calls end up costing a lot less than those made over traditional phone lines. In fact, most VoIP system suppliers include free unlimited calls within the US and Canada as part of their price plans, so you won't have to pay extra for them.
Some – but not all – VoIP suppliers also let you make international calls for free. If yours doesn't, don't worry – international calls made over the internet are still cheaper than those made in the traditional way.
Flexibility and Mobility
Cloud-based VoIP systems can be accessed from anywhere, on any device (cell phone, tablet, laptop, or desktop) that has an internet connection and the system app installed. So, whether your staff are based in the office, working from their own homes, or travelling, they'll be able to make and take business calls, and access the UC features your system includes, like video chat and instant messaging.
With a VoIP phone system, you won't need to pay for additional phone lines or hardware as your team grows. All you need to do is add more users to your VoIP system, and have them download the system app onto their devices. That said, you can use IP desk phones rather than cell phones if you prefer – just contact your VoIP system supplier and they'll provide what you need.
Better Sound Quality
You've probably heard that the sound quality on VoIP calls is pretty bad. After all, when VoIP first started to be adopted on a large scale, that was very much the case. But now, advancements in the technology – for example, IP phones being fitted with noise-cancelling microphones – mean that VoIP call quality is usually fantastic.
As long as you have a reliable internet connection with plenty of bandwidth, you can expect your VoIP calls to be crystal clear. In fact, you can usually count on them sounding even better than calls made via the traditional phone network.
As we've explored in our list of the best business VoIP phone systems, these solutions come with a variety of features designed to make your working life more streamlined, and give your customers and clients a friendly and professional experience when they call your business, no matter how big or small it is.
A Guide to Buying the Best VoIP Phone System
Deciding on the best VoIP phone system for your business is no easy task. Take a look at the following statements for advice on how to find a VoIP phone system that matches your business’ needs…
“I am a small business”
Firstly, think about how many features you need. There are plenty of VoIP suppliers that will offer you a package that promises the earth – but half the features you end up paying for will probably go unused. Look for a VoIP supplier that offers packages that are tailored to small businesses. One of the main stars is 8×8, whose X Series is one of the best VoIP phone systems for those who need a no-frills package.
“I don’t want to spend a fortune”
A VoIP phone system doesn’t have to be expensive. You could even use your mobile phone, tablet, or computer as a phone handset, removing the need for any type of hardware investment. How does this work? Many VoIP providers offer a softphone app, which turns your preferred device into a fully functioning VoIP system. GoToConnect offers one of the most feature-rich softphone apps out there.
“I want to design my own VoIP phone system”
Whether it’s customer relationship management software, booking software, or even field service software, open source VoIP systems allow you to integrate a number of programs so your business platforms are completely unified. You’ll have the ability to customize the code, so your software platform meets your exact requirements. And although you’ll need to pay a tech team to put in the hours, software packages like FreePBX don’t cost a dime to buy.
“I want a VoIP phone system that can handle large-scale operations”
Lots of VoIP providers offer specialist enterprise packages that include all the advanced tools that you need to create a sophisticated unified communications system. Some providers, such as Ooma, include advanced technology, features, and integrations to help large businesses streamline their communications and stay in touch with important clients and each other.
“I’m looking for a VoIP package for my sales department”
When it comes to creating an effective contact center, your software makes all the difference. Call center VoIP software from the likes of RingCentral allows you to communicate with your customers in whichever way they prefer. It also integrates with CRM systems, giving you the freedom to access and store data in the most convenient way for your business.
