14 Best Business VoIP Providers In The UK (Reviews)
Finding the best business VoIP provider in the UK is no mean feat, given that there are some 50+ and that number grows by the day. In this article, updated for 2024, our experts have reviewed the top 14 UK VoIP providers to help you quickly find the right solution for your business.
Based on our in-depth, expert analysis, independent reviews, awards and service levels, we found that the following companies are currently the best UK VoIP providers for businesses:
Short for Voice Over Internet Protocol, VoIP means that telephone calls are made through the internet, rather than a landline, ISDN, or mobile network. A VoIPphone system gives businesses lots of additional functionality to make phone calls. Examples include call recording, call transfer, hunt groups, and even the ability to make calls from mobile phones.
The two types of VoIP systems
There are two ways you can get a business VoIP system; buy the equipment and run it from your office, or subscribe to a hosted VoIP provider, like the UK VoIP providers mentioned in this guide. In 99% of cases today, the latter is the best solution for businesses for various reasons such as reliability and cost. For that reason, in this article, we will focus on hosted VoIP phone systems.
How does VoIP work?
A VoIP phone system works by taking your analogue voice signal and converting it into a digital signal that can be transferred over a broadband line to your UK VoIP Provider.
Unlike traditional phone systems where you need a physical phone, you could use any of the following to make VoIP calls:
A VoIP Phone
A computer with an internet connection
A smartphone with an internet connection
A web browser (with some VoIP phone systems)

What are the benefits of business VoIP?
Regardless of the business VoIP provider you choose; there are some universal benefits you can expect to enjoy:
Lower service costs
Work from anywhere with an internet connection
Free calls - near unlimited calling
Improved portability
Scalability
Advanced features
Clearer voice quality
Flexibility with softphones and mobile apps
Easy to manage via a web portal
Lower costs
Controlling costs in business is vital, which is why the first benefit of VoIP phone systems we want to bring to your attention is that, in most cases, it lowers costs. Of course, how much it reduces costs depends on your current systems, but we would usually expect savings of anywhere up to 50%. Yes, that's right, VoIP services can save you up to 50% compared to a traditional phone system with an ISDN line.
Cost savings vs a traditional PBX
When it comes to a traditional phone system, businesses must invest in handsets and PBX hardware. A PBX on its own can cost thousands of pounds, and while that can often be leased over several years, getting set up still represents a massive cost.
In contrast, by using a cloud-VoIP provider, you do away with the capital outlay and simply charge you per user per month for everything.
Connectivity costs
To run a traditional phone system before VoIP, you needed telephone lines such as ISDN and internal cabling to every desk. Every time you want to add another person to the system, you'd need to get them connected via a cable running back to the PBX; this is, of course, in addition to any networking you need for computers. The great thing with business VoIP systems and handsets is that they run over the same network as your computers, completely removing the need to have a second connection going back to your comms room. Not only that, but they can also even run over wireless, which, while not quite as reliable as a physical network cable, can give you more flexibility over where the handset is located in the office. Finally, as we know, ISDN line rental is costly and is being phased out in favour of SIP lines - by moving to VoIP, all of your calls go over your internet connection so you can rid yourself of one more ongoing cost.
Call costs
Direct savings also come in the form of reduced call costs, with many VoIP service providers even offering substantial free call packages; our favoured options, for instance, give you 2000 minutes to UK landlines and 2000 minutes to UK mobiles per user per month! VoIP calls can be up to 60% cheaper domestically and sometimes up to 90% cheaper internationally than calls via PSTN or ISDN.
Maintenance costs
Another significant cost related to traditional phone systems and handsets is the maintenance costs. When you purchase a PBX, you'll invariably take out a support service alongside it with a local provider so that as or when you have issues or want to make changes, you have someone to call. Those maintenance costs add up, and as your system gets older, you'll likely find that the support fees only increase.
By getting a hosted VoIP system, you remove the need for a maintenance contract to support your PBX. You pay your monthly fee per phone, and the rest is taken care of. You don't own the hardware and therefore don't need to look after it.
Work from anywhere
Arguably one of the most significant benefits given that we are increasingly working from both the office and home is the ability to take business calls anywhere you have an internet connection. With VoIP, you aren't tied to a physical phone line, so you can be anywhere in the world and pick up your business phone. This flexibility is a massive benefit for businesses that embrace home working and hybrid working following the pandemic.
Improved portability
A VoIP number is completely portable, so you can use the same number wherever you go. For people who travel often, this is welcome news as they can appear to be in the office from anywhere. Better yet, if your business changes its address or your employees need to work from home for an extended period, you can all keep your phone numbers; it makes things seamless.
Scalability
Scalability is a benefit often associated with VoIP as it provides business owners with a system that can grow as their company grows. A cloud VoIP solution does away with the need to purchase expensive hardware or a dedicated telephone line as a business grows. Got a new office opening? Simply order a few more handsets and ship them to the site.
Advanced features
VoIP provides you with many advanced features such as auto-attendant and call forwarding that help businesses of all sizes operate efficiently and help small companies project a larger image. Equally, VoIP can help large enterprise-scale organisations present a more approachable image. It all comes down to how the VoIP system is set up.
Let's say you have a Birmingham-based business, which serves clients across the UK, but especially in London. By signing up with a business VoIP provider in the UK, you can get a VoIP phone number with a London area code, even though you're not based there. This gives your customers the impression that you're a local business even though you might not be.
Similarly, the auto-attendant and call routing features can make you look larger than you are. For example, you could be a sole trader, but you've set up your VoIP system to seem like you're a company with several departments.
Clearer voice quality
Today, as long as you have a fast and stable internet connection, voice quality shouldn't be an issue. VoIP calls tend to be clear and crisp, with no latency, lag or call dropout issues.
The key to VoIP call quality is having broadband or a reliable leased line with plenty of bandwidth. If your connection is slow and often drops, it's a warning sign that VoIP might not be the right fit for your business.
Two lines are better than one
At T2k, we typically recommend you should have one internet connection for your VoIP phone service and another for your computers. This separation ensures that employee internet usage doesn't impact your phone calls. If you choose a VoIP service provider who does both phone services and broadband, the other plus is that your calls have less "digital distance" to travel, improving reliability and giving you the best call quality.
What is Unified Communications?
Unified Communications refers to a VoIP phone system that integrates multiple communication methods. A business usually communicates in many ways, such as phone calls, video conferencing, instant messaging, email, SMS, fax, etc. A Unified Communications service connects many of the ways your business communicates, letting them talk to each other in one system and making your business more efficient. The best UK VoIP providers and their systems will typically enable companies to utilise the power of Unified Communications.
How to choose a business VoIP provider in the UK
Whom you choose to provide your VoIP is incredibly important, given that, in all likelihood, you'll be with them for several years. Ofcom offers several tips on things to ask when choosing a VoIP provider, but our thoughts are that you need to make sure they offer all of the following:
Setup for minimal or no capital outlay
The choice between hosted or an onsite solution
UK based customer support
Highly rated and reviewed
In business for a reasonable length of time
A clear track record for high service levels
Experienced with small and large business
Lots of features that match your requirements

3CX is quite different to the other providers on this list as their VoIP solution can be deployed almost anywhere, be that on your premises, in a private datacentre or the cloud. Incredibly, 3CX can even be installed on Raspberry Pi, demonstrating how flexible and lightweight their software is. Unlike the other VoIP providers on our list, with 3CX, you will need to get SIP trunks, too, meaning it's not an all in one solution; depending on how you look at that, it could be a strength or weakness. Another big plus for 3CX over other UK VoIP providers is that it'll do many advanced things out of the box; examples include integration with CRM apps, browser-based video conferencing and much more.
A cursory glance around the internet at reviews, and you'll find that we're not the only ones that appreciate this system.
Highly rated and recognised as an excellent solution
Cons
Need to find your own SIP trunk provider
Requires a partner to set up
Not as easy to manage as other solutions
2. Gamma Horizon
Good all around
9.5/10Our Rating
Gamma and their hosted VoIP phone system Horizon are close to the top of our list of UK VoIP providers. A business-only provider of telecoms services, Gamma operates almost entirely through a network of partners. Their Horizon hosted VoIP platform is award-winning and market-leading, which is why many partners choose it as their hosted VoIP service of choice. The great thing with Horizon is that it is suitable for businesses of all sizes, so even the smallest of companies can use it and then add users as they grow. Bigger companies will find a suite of features that is hard to beat, including integration with CRMs and Micorosft Teams, along with things such as video conferencing and instant messaging.
Horizon customer reviews
As Gamma delivers its Horizon service through a network of smaller UK based partners, there isn't a single place you can go to get customer reviews. Ultimately, the quality of the service is down to the provider you choose.
Make calls from your desktop, laptop or mobile phones
Integrates with popular CRMs
Integrates with Microsoft Teams & Outlook
Excellent support from smaller partners
Cons
Not as flexible as some systems
Supports fewer IP phones
No choice over where the system is located
3. Voiceflex Flow
9.3/10Our Rating
Voiceflex Flow is an advanced hosted telephony solution that adapts to your business needs. It's designed to be a flexible cloud-based VoIP service that offers Unified Communications, allowing your workforce to stay connected from anywhere with an internet connection.
Voiceflex Flow is packed with features and integrations, enabling seamless connectivity with your existing CRM systems and other business software. Whether you're looking for robust call management, real-time monitoring, or reliable business communication tools, Voiceflex Flow provides a comprehensive solution. It also includes options for audio and video conferencing, ensuring your team can collaborate effectively no matter where they are.
RingCentral is the first of the global players we've included in our VoIP market review. Although the system is excellent, as they are a global company with so many customers, it seems they find it challenging to provide high-level service to everyone. RingCentral has positioned itself as arguably the biggest provider of VoIP phone systems globally, with a massive presence in the US, UK, and Europe. For a good reason, their enterprise-grade VoIP solution is comprehensive, giving businesses access to an extensive suite of tools designed to level up their communications. The only downside with RingCentral, a common theme with the international players in the market, is that their support can be patchy, as highlighted by their meagre score of just 2.4 out of 5 on the reviews platform Trustpilot. For this reason, we score them lower than the UK VoIP Providers Gamma and 3CX in particular.
It's fair to say RingCentral has mixed reviews, with a pretty low score of 2.4 out of 5 on Trustpilot but a far more respectable score of 4.5 on Gartner Peer Insights. Like some of the other big players in this list, while you will likely get all of the business VoIP features you need and more with RingCentral, you will be relatively unimportant to them. Therefore, the customer service levels could be questionable.
Global company and a good choice for international businesses
Integrations with over 250 apps
Excellent system security
Works across your computer, tablet and phone
Used by some of the biggest companies in the world
Real-time analytics for phone and meetings
Eliminate IT overhead with one system
Scale-up and deploy new users very quickly
Work from anywhere
Quick setup
Cons
Negative customer reviews
Patchy UK support
5. 8x8
8/10Our Rating
8x8 is another of Gartner's leading Unified Communications providers and is a global VoIP business, also opertating in the UK. As you might expect, their business VoIP service is packed full of features, so many so we'd be hard-pushed to list them all out. As we'll look at in a moment, perhaps the only thing counting against 8x8 is its customer service levels, as their reviews currently show.
Similarly to the other top VoIP providers we've looked at, the 8x8 eXperience Communications Platform is much more than a phone system; it's a suite of communications tools. Across phone, video, messaging, and even team chat, 8x8 is there to empower your employees and, in turn, delight customers.
8x8 customer reviews As we've suggested, the only thing counting against 8x8 is its reviews from existing customers. Their current Trustpilot rating is just 3.9, which puts them among some of the lowest scoring providers on this list. As we've suggested, this doesn't mean they always provide a poor service, but it seems they have more unhappy customers than, say, bOnline or T2k.
Embeddable communications with a developer-friendly API
Works with Microsoft Teams
Global reliability
End-to-end encryption
Integrates with CRMs
AI-powered workflows
Video meetings, 1:1 and aa-hands
Works in a web browser
Unlimited calling, SMS and fax
Cons
Relatively poor customer review
Comparably expensive provider
6. bOnline
8/10Our Rating
bOnline is an exciting company in that they provide far more than just VoIP phone systems; they also do things like web design. As a UK VoIP provider their solution is focused very much on smaller companies that are perhaps looking for their first phone system.
Unlike many global providers, bOnline positioning itself as small business-friendly, offering "honest pricing" and short contracts. Only tying customers in for a short period gives companies the flexibility to move away if they're not happy with the service and arguably means that bOnline is exceptionally confident in its VoIP service. Another plus is that they are a UK based company, so they are better placed to provide high levels of customer support.
bOnline Reviews
bOnline has amassed an impressive haul of over 7,000 reviews and has a current Trustpilot score of 4.6. That's incredible considering the number of reviews and demonstrates the high quality of both their business VoIP solutions and their customer service.
Vonage is one of the market leaders for Unified Communications, offering more than mere VoIP to consumers and businesses alike. While Unified Communications might seem like jargon reserved for only the most prominent companies, Vonage is actively pushing it into smaller businesses.
Ultimately, it's a hosted VoIP service, but it's packed full of features that enable you to integrate your communications into a single platform. Vonage Business Communications looks to streamline Voice, SMS, team messaging, fax, video meetings, etc.
Vonage Reviews Vonage talks a good game, and there is no doubt that their service is packed full of features, but looking at their reviews on Trustpilot, they still have some work to do. Currently, they score 3.9 stars out of 5 from over 600 reviews. A consistent complaint seems to be how hard it is to contact Vonage when there is an issue, which is unfortunately often the case when you work with these larger companies.
4com provide several hosted VoIP options and on-premises systems too. They primarily run on HiHi phones, which enable advanced functionality like Unified Communications (UC), so integrating into other platforms should be a breeze.
According to 4Com, their Hihi phones are suitable for businesses ranging in size from 3-100 employees, making it a good fit for UK based SMEs.
Having been in business for some 20 years, 4Com has established itself as a leading VoIP reseller in the UK.
4Com Reviews 4Com currently enjoys a Trustpilot score of 4.8 out of 5 stars, which is impressive given the number of customers. Similarly to us here at T2k, it would seem that 4Com takes looking after its customers seriously, which shows in their reviews.
Gradwell is a well-established telecoms provider based in Bath. With a large team and an extensive client base, they can support almost any company that looks to them for VoIP. Alongside their VoIP offerings, they also provide services such as connectivity and software; they are a modern-day communications partner by all accounts.
With thousands of customers across, including many well-known brands, Gradwell is undoubtedly one of the top VoIP providers in the UK.
Gradwell reviews
Gradwell are one provider on this list whom we know are very good, but it seems of late their service levels have slipped somewhat. Currently, their Trustpilot score is hovering around 3.9 stars out of 5. However, the frequency of 5-star reviews seems to be increasing, signalling perhaps the resolution of some of their troubles.
No limit on capacity, so it can grow with your business
Excellent resilience
Cons
Sometimes poor support, as highlighted in customer reviews
Somewhat dated phone system
Moved backwards in recent years
10. Lily Comms
8.3/10Our Rating
Lily Comms is a VoIP reseller, meaning they don't have their technology; they add value to other's platforms. They have a range of solutions available from some of the best VoIP providers. The advantage of working with a reseller like Lily is that you'll usually get better levels of support than you would be working with a global provider.
Lily Comms Reviews Lily Comms is comparable to T2k in that they currently have a score of 4.9 out of 5 from their customer reviews on Trustpilot. This is encouraging not only for Lily but for T2k too, as ultimately, we both use the same underlying technology to deliver services to customers.
Award-winning provider of communications and IT solutions
Highly rated on Trustpilot
Partner of multiple leading tech companies
Tailored services
Choice of underlying VoIP platform
All customers get a dedicated account manager
24/7 support options
Cons
Some customers mention poor call quality in their reviews
11. BT Business
7/10Our Rating
BT is synonymous with telecoms, being that it's the oldest phone company in the world. Today, it provides various services domestically and to the corporate market, from TV and mobile to business VoIP systems.
While perhaps not everyone's favourite company, it has to be said that they must be doing something right to be where they are.
BT Business Reviews BT's reviews are, in all honesty, pretty poor; they're a huge business and therefore taking care of individual customers tends to be complicated. This is represented in their currently Trustpilot score of just 1.2 out of 5. However, it should be noted that they aren't actively asking their customers for Trustpilot reviews, so it tends to be only the people who have had negative experiences that take the time to find their profile and leave a review.
Integration with mobile devices so you can work from anywhere
Call forwarding, routing, Voicemail and more
Call Recording and monitoring
Extensive CRM integration
Cloud-based with simple admin portal
Instant messaging
Video Conferencing
Cons
Often poor levels of support
Difficult to contact them
Sometimes poor voice quality
12. Virgin Media Business
7/10Our Rating
Virgin Media are another well-known name on our list of the best providers, whom you will undoubtedly have come across for in the very least domestic TV and phone services. But they also provide a range of business VoIP services to complement their other offerings, such as business internet connectivity. Virgin provides several VoIP solutions, including backing off to another leading provider in this list 8x8. As much of their business VoIP service is backed off to 8x8, please refer to that review higher up this page for more information.
Virgin Media Business Reviews We're sorry to say that the situation for Virgin in terms of reviews is very similar to that of BT. As they aren't actively encouraging customer reviews, their Trustpilot profile is littered with complaints. Of course, as is always the case with reviews, they should be taken with a pinch of salt, but overall, the picture isn't too positive.
SureVoIP is one of the few providers on this list to boast their independent network and business VoIP solution. With a national MPLS enabled network, they provide a high-quality and high-reliability service. Perhaps not as well known as others on this list, they are a genuine contender in the market, having won various industry awards in the past few years.
Sure VoIP reviews SureVoIP collects their reviews via Reviews.io and currently have a rating of 4.48 out of 5, with 90% of reviewers recommending SureVoIP. This high score demonstrates their commitment to quality and customer service and justifies their inclusion in this list of best VoIP providers for business.
All of their business VoIP services provide HD Voice quality
Voicemail to email as standard
Choice of handsets along with desktop and smartphone softphones
Fully encrypted calls for security
Port numbers over and get new ones
Call Recording and conferencing
Auto-attendant and IVR options
Cons
Some reviews state that simple issues aren't solved efficiently
14. Microsoft Teams
8/10Our Rating
The final VoIP provider we've reviewed is Microsoft and their business communications platform Teams. Many of you will already know of and use Microsoft Teams, and there's an increasing number of companies that are not enabling it for voice. However, it's not without its faults, with high costs and patchy support, but it is worthy of being on our roundup.
Microsoft Teams reviews Microsoft collects reviews for their Teams product on TrustRadius, where they have a very good score of 8.1 out of 10, one of the highest of any of the global companies we've reviewed.
Limited functionality in comparison to other cloud PBXs

What to look for in a VoIP phone system
When you're changing your phone system, you want to ensure that whatever you move to won't just save you money but give you a reliable platform for growth. You want to maximise productivity and give your team the tools they need to provide brilliant customer service. Business-focused features that emphasise control and administration take the burden of management away from you and improve profitability.
In our opinion, you should always look for a UK VoIP provider with exemplary support, as your phones are central to the performance of your business.
Find a system with an easy to use interface
Most, but not all of the top providers, will give you a web portal where you can log in and manage your phone system. Here are some of the options you'll have:
Cloud VoIP improves team working through a variety of features; many of which should be included as standard with your VoIP system's subscription:
1) Adhoc conferencing
Start a conference at any time, without scheduling a meeting, simply drag and drop users from your contacts to an open within, and you can enjoy all of the features of a planned conference.
2 ) Hunt Groups
Distribute calls across your team using Hunt Groups; it doesn't matter where the team is based, or even if they're in the same office; if they're in a group and available, they can be included in your call routing. Choose from the following five ways to call the group:
Circular - Sends calls to users based on their position in a list
Regular - Sends calls to the next available user in the hunt group
Simultaneous - Sends incoming calls to all of the users at the same time
Uniform - Send the call to the user who has been idle the longest
Weighted - Assigns calls to users based on percentages you set in the Hunt Group
3 ) Call transfer
Transfer calls to any internal or external number quickly and easily, and not only that, easily receive the call back if no one answers. Simply enable the settings, and you'll have the option of how many times a transferred call should ring before it's transferred back to you. You don't need to answer either; using Blind Transfer, you can transfer a call without speaking to the person.
4 ) Common or customisable settings for sites, groups and departments
Reduce admin and maintain consistency across the organisation by grouping sites, teams and departments together. Changes in settings can then be rolled out on a per-site, team or department basis.
5) Call park
Put a call on hold and pick up another phone, giving you the flexibility to move around the office and even switch to a mobile device or computer.
6) Call Pick-up
Is someone in the team away from their desk? With Call Pick-Up, you can take the call and tell the person when your colleague will be back. This feature allows you to answer colleagues' phones and pick up call-waiting calls.
7) Call Waiting and music on hold
Call waiting for queued callers and ensure you're ready to take the next call. With music on hold, you can choose to play waiting music or even promotional messages while your customers wait.
8) Auto Attendant
Auto-attendant provides menu options to callers so that their call can be routed to the correct person or team. You can create a bespoke schedule that enables the auto-attendant only during working hours and disables it when the office is closed for a holiday.
Features to improve efficiency
VoIP phone systems provide a range of features specifically designed to help your team maximise their efficiency.
1) Last number redial and click to dial
Quickly redial the last number that was called, received or missed and use your computer to Click to Dial anyone in your contacts list.
2) Presence or Pre-set Availability
Manage incoming calls with Presence and Pre-set Availability; if you know you're not going to be available, your business phone needn't ring. Call routing can take the caller to someone available. Choose from four different availability profiles:
Available In Office
Available - Out of office
Busy
Unavailable
These profiles include the ability to manage incoming call functions, for example, Call Forwarding, Busy, Voice Messaging and Call Notify.
3) Anonymous call Rejection or Selective call Rejections
Anonymous Call Reject allows a user to reject calls from people that have restricted their caller ID. By activating the service via your provider's web portal, callers without identification will be informed that the user isn't accepting calls. The user's phone won't ring, and the user won't see or hear any indication that a call was attempted. This service, of course, doesn't apply to calls from within the business or group.
4) Auto Call Back and Busy Lamp Keys
If you call another person in your company and are busy, you can use Automatic Call Back to be notified when they're off the phone. Equally, you can have Busy Lamp Keys on your phone handset, which show you whether another user is on a call or not.
5) Do Not Disturb
Do Not Disturb will show you're unavailable and automatically reject attempted calls or transfers.
6) Company Directory
With Company Directory, you can assign up to 100-speed dials for your favourite numbers. Save time and avoid having to search for a popular number.
7) Call Recording
Use call recording to create audit trails and ensure compliance. Equally, you can use call recording for training purposes and quickly and easily listen back to calls that have taken place.
Mobile and flexible working
VoIP services give you and your team so much flexibility to work from anywhere. Enjoy features such as Call Forwarding to manage calls effectively, Home Worker to take profiles and settings home, Voicemail to email to never miss an important call, and Hot desking to move around and work from anywhere.
Best business VoIP phones
The phones you get for your new VoIP phone system play a big part in your team's experience. VoIP phones come in all shapes and sizes, but one thing to bear in mind is that not all phones will work with all UK VoIP Providers' systems. While we can show you some of the best handsets on the market, it's always wise to speak to your VoIP provider to find out what they offer.

Tips when choosing a business VoIP provider
It can be challenging to know their differences with hundreds of UK VoIP providers to choose from. This section gives you our top tips to consider when you're choosing your VoIP provider. Click here if you'd like a more detailed guide to choosing a business VoIP system.
Price of business VoIP services
Prices between business VoIP providers can vary quite significantly, so it's essential to get several quotes to understand what they will charge you per month.
Work out how many minutes you use approximately per month and then see if it's worth paying a set fee for a certain number of minutes, or would it be less expensive with a pay-as-you-go VoIP provider?
Spending an hour researching the options will ultimately save you a lot of money on calls.
Quality of business calls
We always recommend researching the business VoIP providers you're speaking to understand their customers' thoughts.
Business VoIP services require a significant amount of investment to keep them operational, so you need to know that you're in safe hands as a customer.
Ease of use of the VoIP platform
Some VoIP providers will provide you with complicated instructions that are difficult to follow and make using the system a real struggle. Others will install for you and be on hand to give you training on how to use the system. Look for a provider that offers you that level of customer service as you must have got a good grasp of the system.
If you're pretty technical already, this may not be too important to you, but the simpler, the better for everyone else.
Choose a business provider for the features you'll use
The functionality that business VoIP systems provide is far greater than you'd expect from a traditional phone or even a PBX system; because of that, you'll want to make sure you familiarise yourself with all of the things the cloud-based platforms you're looking at can do.
While many of these features will be included in your monthly service fee, some will attract an additional charge, so speaking to each provider to establish what it'll cost for you to use such features is essential.
Can you scale the service up and down?
VoIP allows your business to connect your staff quicker and easier than ever before, but what happens if your business grows or shrinks?
In most cases scaling a VoIP service up won't be an issue, and the provider you're working with will be more than happy to sell you another license for the platform. But what happens if you need to reduce the number of subscriptions you have? Make sure you speak to the VoIP provider about this; the last thing you want is to be tied into a contract for a person no longer in the business.
How secure is the VoIP service?
Technology can be prone to security threats, so understand what security measures are in place to protect your VoIP calls. Can you imagine what might happen if you were, for instance, using call recording and someone got their hands on all of your recorded calls? It doesn't bear thinking about, so make sure you check with your VoIP service provider whether they support secure communications and what measures they have.
Customer support and reviews
As you use the hosted VoIP service, there will likely be certain things you need assistance with, so check with your provider what level of customer support they provide. The best VoIP providers will offer telephone-based support, and we suggest avoiding those that only offer live chat.
Choice of phone numbers
The great thing with business VoIP phones is that you can have a phone number anywhere in the UK. This is great if you're running a market campaign in one city but located somewhere else; all of the calls will still come through to your business phone, but you appear to be local from the customer's perspective.
Number porting
Phone number porting is the process of moving your existing phone number over to the new service. Check with your account manager or customer service that this is available before taking the service out to ensure you can keep your number.

How do I set up a VoIP phone system for my small business?
Start by requesting a comparison quote via our website. We'll match you to a phone system, and assuming you're happy to go ahead; we'll support your switch. Generally speaking, the system will be set up in a couple of days, but it can take weeks to transfer (port) any numbers you wish to keep. In our experience, from start to finish, you should have completed the switch in under a month.
Why is VoIP so much cheaper?
As VoIP is based on the internet and has almost unlimited capacity, the cost of calls and VoIP is very cheap compared to older technologies. You also benefit from less physical cabling being required in your business premises, and you don't even have to buy handsets if you don't need them. Many businesses that switch to VoIP report savings of up to 47% compared to traditional phone lines and systems.
Should businesses switch to VoIP?
Yes, for several reasons. Firstly, traditional telephone lines such as ISDN and PSTN are being turned off in 2027, so all businesses will need to switch before then. The good news, though, is that VoIP is usually cheaper and comes with many additional features that'll improve efficiency and profitability in your business.
Does my business need VoIP?
All businesses will need to switch to VoIP before 2027 when BT turns off their traditional phone lines. However, many companies are making the switch sooner rather than later because VoIP is much better than older technologies. You get many more features, usually for a significant reduction in costs.
Small businesses stand to gain significantly by switching to VoIP. Not only do you stand to make significant savings on calls, but you'll also benefit from a whole host of additional functionality. Many businesses wish they made the switch sooner; there's almost no reason you shouldn't switch to VoIP.
How do I choose a VoIP provider?
Start by working out what functionality you need from your phone system, and then find a provider that'll fit your needs. Next, consider the service price; as you'll be paying a monthly fee, you must get a good deal to avoid overpaying in the long term. Finally, decide how important it is for you to have a point of contact with your chosen provider. If you're not too worried about being able to speak to someone, then you might find one of the big providers fits your needs; however, if you think you'll benefit from occasionally speaking to an account manager, then perhaps a smaller company such as T2k would best suit you.
Do I need a provider for VoIP?
Yes, in 99% of cases, you'll need a provider if you want a VoIP phone service. A small number of technology companies, such as those in IT, might be able to set up a system using free software and SIP trunks, but they tend to be few and far between.
What's better VoIP or landline?
VoIP is better; it gives you far more features, and considering that BT's PSTN telephone lines (landlines) will be switched off in 2027, the question is relatively academic.
