Get a tailored quote What is a VoIP system?VoIP stands for “Voice over Internet Protocol,” which basically means that the phone connection operates over Wi-Fi and not physical phone lines.VoIP systems can be used on laptops, desktop computers, tablets, or smartphones. It can also be used with office phones, the best office phones are usually compatible with major VoIP systems, but if portability is a priority, tablets and smartphones can also make VoIP calls.By using Wi-Fi connections, the calls are cheaper, can go long-distance more efficiently, and are more reliable than a standard phone line. Some providers also offer HD voice quality, which means they can sound clearer than standard phone calls.VoIP phone systems enable much cheaper domestic calls, and low price-per-minute international calls, too.Soon it will be necessary for all businesses to be online due to the “Big Switch Off”, in 2025, when all UK landlines will officially be turned off.

We found that 8x8 is the best overall VoIP system for UK businesses. Scoring incredibly well across a number of categories, its standout range of features, strong security, reliable customer support and scalability options see it earn an overall score of 4.7/5 – our highest rating. Read more + Read less - Strengths Offers the best variety of features, with super generous video and call conferencing Excellent 24/7 customer support - better than GoTo and Nuacom's offering Lots of security features, including encryption and compliance certifications Best capacity to scale up out of all competitors Weaknesses Can become expensive, with prices reaching as high as £135 per user, per month No spam prevention, while this is offered by GoTo and Vonage Overall customer satisfaction score is lower than other providers 8×8 is a global VoIP provider, with data centres distributed across 35 different countries. Its customer support teams are available 24/7 from various international locations. If you're keen to deal with a more UK-based company, 8×8 may not be the best route. That being said, its European headquarters are based in London. Its global coverage will be excellent for teams that deal with international clients or have employees spread across the globe.8×8 VoIP PricingAffordability is not 8×8's forte, it scores an average 2.5/5 for price in our analysis, placing it as one of the most expensive phone systems on the market. That said, 8×8 is bursting with more standout features than its competitors.A plus is that it offers five pricing tiers for different-sized operations, the latter three are best suited to larger call centres. As of February 2023, 8×8 no longer offers its cheapest ‘Express' plan. The lowest tier is now its X2 package, starting at £19 per month, per user (billed annually).Check out our full-length 8×8 review for more information.

Integrating with one of these is a great way to develop a great customer experience strategy.8×8’s security features also impressed us, with multiple compliance certifications, multi-factor authentication, password rules, and TLS/SRTP encryption, so we awarded it full marks with 5/5. With that being said, 8×8 does fall short in the department of spam prevention, where GoTo and Vonage excel.If you choose to invest in 8×8 now, you can avoid switching providers later down the line because its plans have the capacity to grow with your business, earning it a 4.9/5 for scalability.We gave 8×8 top scores for customer support. 8×8 has a user forum and a knowledge base to explore, a 24/7 live chat function, and a phone line for urgent matters. Email support is also available for your queries that aren't time-sensitive.Despite offering great customer support, it achieved lower overall scores on consumer review websites with an average rating of 3.5/5 compared with 4.6/5 and 4.5/5 for Nuacom and bOnline, respectively.X2X4X6X7X8Unlimited domestic minutes✓✓✓✓✓Unlimited international minutes✓ To 14 countries✓ To 48 countries✓ To 48 countries✓ To 48 countries✓ To 48 countriesLocal numbers✓✓✓✓✓Ring group✓✓✓✓✓Call queues✓✓✓✓✓Video callingUp to 500 peopleUp to 500 peopleUp to 500 peopleUp to 500 peopleUp to 500 peopleCall conferencingCRM conferencing✓✓✓✓✓CRM integration99.999% Uptime SLAOnboarding support‘Customer Success Managers’, likely at an extra chargeLive customer support24/7 live chat and phone lineOne thing to note is that 8×8 is one of the most generous VoIP providers when it comes to call conferencing and video meetings, with a capacity for a whopping 500 people to join in at once. This is ideal if you often hold company-wide meetings, or you’re looking to scale your business at pace. What's new for 8x8? August 2023 Agents can now access their own analytics.

RingCentral – Best business VoIP provider for customer service teams RingCentral 4.5 Pricing £7.99 – £29.99 Get free quotes RingCentral review Why is RingCentral best for customer service teams? We awarded RingCentral 4.5/5 overall, making it a close second to 8x8. An excellent option for customer service teams specifically, its customer support availability and scalability are second to none. Read more + Read less - Strengths Excellent customer support, tied with 8x8 for the best score Offers an excellent range of ready-made integrations Comes with a great range of features, second only to 8x8 Tied with 8x8 for the best scalability score Weaknesses Doesn't offer great value for money, scoring 2.3/5 in our cost analysis Overall customer review score of 3.5/5 No first-party desktop phones RingCentral is another provider with data centres spread across the globe. With coverage in 24 countries, RingCentral is a suitable provider for both global and UK-based teams. While RingCentral provides a UK help number and has an office in West London, its not confirmed whether this is where its call centre is also based.RingCentral VoIP PricingAt first glance, RingCentral is an affordable option, and it's cheaper than 8×8. However, it received a lower score of 2.3/5 for pricing because on closer inspection, you’ll find that it offers less value for your money. As you’ll see in the analysis of the key features below, the majority of RingCentral’s standout features are only unlocked once you upgrade to a premium package.Its minute allowances, in particular, are limited on entry-level plans, while other providers offer unlimited minutes right from the off. If you want a system that is great value for money, GoToConnect and bOnline offer cost-effective plans.

RingCentral boasts a great range of features to accommodate this, including a virtual receptionist, local toll-free numbers, as well as customisable greetings and hold music on all of its plans, so we gave it a 4.3/5 in this category.When you upgrade to a Premium or Ultimate plan, you can set up ring groups and call queues that will help organise your callers with ease. RingCentral also comes with external video calling and SMS features, maximising your team’s accessibility for your customers.A really important factor for small businesses looking to upscale their operations is whether a provider can grow with you. RingCentral’s scalability is on par with 8×8, scoring a near-perfect, 4.9/5. This is because it offers a wide range of features such as team messaging, task management, and software integrations (on Premium and Ultimate) to streamline your internal and external communications.We think that RingCentral excels with its customer support, as it offers support in a range of formats, including 24/7 live support, a knowledge hub, a user forum, as well as phone and email support. Its 99.999% uptime SLA guarantee means your system will stay connected and your customers will be able to get hold of you. All this combined earned it a perfect score of 5/5.Of course, training is critical in the world of customer service – your team’s phone manner is all important. RingCentral comes with features that can help with this, including call transcripts, call recording, call monitoring, call whisper, and call barge. It is worth noting that these are not included in RingCentral’s cheapest packages, so you’ll have to pay a little more for the full breadth of training and monitoring tools.It’s worth mentioning that RingCentral comes with ready-made integrations with helpdesk, workspace, email, conferencing, and messaging platforms. It'll make it easy to manage customer data and unify your comms. Once again, though, most of this is only included with RingCentral’s Premium and Ultimate plans.RingCentral is hot on 8×8’s heels in many aspects, with a breadth of features that come closer to 8×8 than any other provider. It just falls short of matching it, missing benefits, such as unlimited domestic minutes, and features that include custom call lists. Plus, ready-made integrations are available on fewer of its plans. However, it does match 8×8’s shining customer support offering, and provides just as much scope to easily scale your business. It also matches 8×8's relatively moderate score on consumer review websites, with an average rating of 3.5/5, compared with Nuacom and bOnline's higher respective scores of 4.6/5 and 4.5/5.For more details on features, read our RingCentral review.RingCentral’s key features for businessesEssentialsStandardPremiumUltimateUnlimited domestic minutes✘ 0 inbound, 100 outbound*✘ 250 inbound, 750 outbound*✘ 1,000 inbound, 2,000 outbound*✘ 2,000 inbound, 4,000 outbound*International minutes✘✘✘✘Local numbers✓✓✓✓Ring group✘✘✓✓Call queues✘✘✓✓Video calling✘Up to 100 peopleUp to 200 peopleUp to 200 peopleCall conferencing✘✓✓✓CRM integration✘✘✓✓Uptime guarantee99.999% Uptime SLA99.999% Uptime SLA99.999% Uptime SLA99.999% Uptime SLAOnboarding support✘✓✓✓Live customer support24/7 live chat and phone line24/7 live chat and phone line24/7 live chat and phone line24/7 live chat and phone line*inclusive minutes per account, per monthOne thing to be aware of is that RingCentral’s Essentials plan does what it says: it provides VoIP system essentials, but not a lot more. On RingCentral’s higher tiered packages you’ll find things like video conferencing, CRM integrations, and generous inclusive minutes. So, if you’re running a larger operation with more varied needs, do bear that in mind.That said, once you do have access to CRM integrations, you’ll almost definitely be able to conjoin RingCentral with your system of choice – it can integrate with 97 different CRM apps!

Vonage – Best VoIP provider for small businesses Vonage 4.4 Pricing £10 - £25 Get free quotes Vonage review Why is Vonage best for small businesses? Vonage is our top choice for small businesses. It offers excellent value for money (beaten only by GoToConnect), with plenty of features, such as video conferencing and team messaging, even on their cheapest plans. Unlimited domestic minutes only kick in on the Professional and Ultimate plans but these packages are still affordably priced. Read more + Read less - Strengths Great value for money, with affordable pricing plans Easy to scale, scoring our second highest score and beating GoTo Connect, Nuacom, and Dialpad One of the only providers with a spam prevention feature Weaknesses Less generous features than 8x8, RingCentral, and Dialpad, lacking a power dialer, an auto-dialer, and an predictive dialing Weaker security features, doesn't offer multi-factor authentication or password rules Weaker external connections than 8x8 and Ring Central (as it doesn't offer email integration or analytics) Vonage is another global VoIP provider, with data centres in the US, Singapore, Sydney, Frankfurt and Dublin. International data centres can be a plus for global teams, however, if you deal with sensitive data, you may feel more comfortable signing up with a provider that is based in the UK or EU and therefore subject to data protection laws. It also has a globally distributed network of offices including one based in London, although its not clear whether its call centre is also London-based.Vonage VoIP PricingVonage’s value for money is its key strength, earning a score of 4.3/5 for pricing in our books. With prices ranging from just £10 to £25 per user, per month, Vonage’s monthly fees are incredibly low for such a comprehensive system. It gives users unified communications features, including video conferencing and team messaging, which are available on all plans.

This feature is available on all plans at no extra cost, so even smaller budgets can benefit.Small businesses are often looking to grow, so it’s important to choose a provider that can grow alongside you. Vonage excelled in our scalability comparison, scoring 4.5/5 on this front. The ring group, call queue, and call routing features on Vonage’s advanced plans will help your team handle the growing volumes of calls, while call recording, monitoring, and analytics will help you train new staff and ensure the quality of your business’s comms is top-notch.Vonage offers a decent amount of customer support, including a user forum, a knowledge base, live chat, email, and phone support. For immediate support, it's best to contact them on live chat, between 8am – 6pm, Monday to Friday or on Saturdays from 9am until 5:30pm. Finally, Vonage’s 99.999% uptime guarantee means it’s unlikely that your all-important income stream will be unexpectedly affected by downtime, which is a huge plus.As we've mentioned, Vonage offers great value for money. In this respect, it almost beats all of the VoIP providers on this list. The exceptions are bOnline, which offers a very similar level of value for money (bOnline is cheaper than Vonage, but also less robust); and GoTo, which offers the best bang for your buck.Vonage is quite popular with its users, earning a decent 4/5 score on consumer review sites.Read our in-depth analysis of the best phone systems for small businesses.Vonage’s key features for businessesSelectProfessionalUltimateUnlimited domestic minutes✘✓ To domestic landlines✓International minutes✘✘✘Local numbers✓✓✓Ring group✘✓✓Call queues✘✓✓Video calling✓✓✓Call conferencingUp to 3 people free, up to 30 at an additional costUp to 3 people free, up to 30 at an additional costUp to 3 people free, up to 30 at an additional costCRM integrationAt an additional costAt an additional costAt an additional costUptime guarantee99.999%99.999%99.999%Onboarding supportAt an additional costAt an additional costAt an additional costLive customer supportLive chat and phone lineLive chat and phone lineLive chat and phone lineSomething that’s likely to jump out at you is how many of these key features come at an additional cost.

GoToConnect, is our top choice for startups. When starting a business, it’s vital to optimise value for money. GoToConnect was our top scorer in this category, earning 4.5/5 – a great choice for helpful features like unlimited domestic minutes and multiple communications channels for a small price tag. Read more + Read less - Strengths Offers the best value for money out there Great reputation among customers, with an average review score of 4.4 International calling to over 50 countries Weaknesses Fewer ready-made integrations than the other providers (except Dialpad) No 24/7 customer support or live chat, unlike 8x8 and Ring Central Slightly lower uptime guarantee of 99.996%, lower than Ring Central, 8x8, and Vonage US-based GoTo is operated out of Boston, Massachusetts yet has a global network of data servers. Rather than by location, servers are assigned based on traffic and availability. Data is stored in the US so will not necessarily be handled according to EU or UK regulations. Since GoTo relies mainly on its online knowledge hub and virtual assistant for customer support, this can be reached from anywhere in the world. If you value being able to speak to a local customer support agent, this may not be the provider for you.GoToConnect VoIP PricingIf bang for your buck is what you’re after, GoToConnect might be the right choice. Earning a top score of 4.5/5 in our pricing analysis, GoTo offers the best value for money out of all the VoIP providers we assessed.Check out our in-depth GoToConnect review.

With its Standard plan, GoTo includes free international calling to and from 50+ countries, while still providing solid, unified communications features for collaboration across the board.As your startup accrues a customer base, you’ll need a VoIP system that can help you communicate with potential customers and clients as professionally as possible. With GoToConnect, you can set up: a virtual receptionist, customisable on-hold music, recorded greetings, and voicemail capability. This will give callers a polished experience when they get in touch.We also like that you can also set up local numbers, so customers don’t have to pay to phone you. All of these features are all available on GoTo’s cheapest package, which is great for budget-conscious new businesses.Of course, it’s likely that you won’t stay the size of a startup forever. Fortunately, GoToConnect’s unlimited user limit and available call management features mean it’s a scalable system, earning a scalability score of 4.4/5 in our analysis.GoTo is let down by its customer support, only earning a 3.4/5 in this category. Its support team can be reached by email or phone and agents are available around the clock to answer queries. However, there are a number of steps to go through before the support number is available and they do not offer live chat. It seems GoTo encourages the use of its knowledge hub, which can be accessed at your convenience. Compared with providers such as 8×8 and RingCentral, who offer live chat, GoTo could offer more straightforward support options to quickly squash issues when they arise.We rated GoToConnect easier to scale than Nuacom, Dialpad, and bOnline. Its strongest advantage is the fact that it offers better value for money than all of the providers on this page.As mentioned, GoToConnect didn't fare so well when we compared integrations. Only Dialpad has a smaller range of ready-made integrations than GoToConnect – the other providers on this page all come ready to integrate with a larger range of software. It's also worth noting that GoToConnect's array of features isn't as comprehensive as the feature sets you'd get with 8×8, RingCentral, Dialpad, or Vonage.When compared with its competitors, GoToConnect does well, with an average customer review score of 4.4, better than 8×8, RingCentral, and Vonage.GoToConnect’s key features for businessesBasicStandardPremiumUnlimited domestic minutes✓✓✓International minutes✘✓ To 50+ countries✓ To 50+ countriesLocal numbers✓✓✓Ring group✓✓✓Call queues✓✓✓Video callingUp to 4 peopleUp to 150 peopleUp to 250 peopleCall conferencing✓✓✓CRM integration✓✓✓Uptime guarantee99.996%99.996%99.996%Onboarding support✓✓✓Live customer supportPhone linePhone linePhone lineThe first thing you might notice here is that even GoToConnect’s cheapest plan comes with the vast majority of the features we know to be the most important for businesses, proving it is great value for money. However, it doesn't include international minutes, but these are unlikely to be integral to a UK startup’s operations.That said, there are a few other weaknesses to pluck out from our key features analysis. GoToConnect provides free CRM integration, but it can only integrate with Salesforce or Zoho. Compared with RingCentral’s ability to integrate with 97 different CRM systems, GoToConnect comes off as a little stingy here. Of course, this won’t matter if your CRM of choice is Salesforce or Zoho. As mentioned before, its customer support leaves a little to be desired with its lack of live chat.Finally, it’s worth noting that GoToConnect’s video conferencing platform will only allow up to four participants per call on the Basic plan. This will be enough for you if your team is no larger than this, but you should bear in mind that, as your team grows, you may need to upgrade to the Standard plan for larger, video-based meetings. What's new for GoToConnect? August 2023 A new feature called ‘Conversation Review' provides a better understanding of customer interactions. It includes call recordings and essential call details. 5. bOnline – Best business VoIP provider for desk phone compatibility bOnline 3.9 Pricing £6 – £15.50 Get free quotes Why is bOnline best for desk phone compatibility? We found that bOnline is compatible with the biggest variety of third-party desk phone manufacturers. All the VoIP systems we analysed are compatible with one to four desk phone brands – except for bOnline, which is compatible with seven: Panasonic, Yealink, Poly, Aastra, Alcatel, AudioCodes, and Htek. Read more + Read less - Strengths Good option for small businesses, offering great value for money beaten only by GoTo Connect Excellent reputation among customers, with an average review score of 4.5, beaten only by Nuacom Can also provide business fibre broadband, and web design services Weaknesses Offers fewer features than all the other providers, except Nuacom. It's missing spam prevention, an auto-dialer, and custom call lists CRM integration costs £5 extra on the cheaper plans Lacks security features, like user permissions, multi-factor authentication, and compliance certificates bOnline is aimed at UK-based small businesses. It has earned an ‘Excellent' rating on Trustpilot partly due to its helpful customer service based out of its offices in Surrey. While its team may be UK-based, its data is unfortunately not. With ‘geographically dispersed' servers, we can't be 100% certain of the locations. Therefore, if your company deals with sensitive or personal data, you may feel more confident dealing with a provider that stations its servers in the UK or EU.bOnline VoIP PricingbOnline’s pricing is one of its major strengths, earning a good score of 4.3/5 in our cost analysis. Ranging from just £6 to £15.50 per user, per month, it’s one of the cheapest VoIP providers you’ll come across. With unlimited minutes available on most plans, as well as free Yealink T31P desk phones on the Unlimited & Video package, bOnline offers excellent value for money. Swipe right to see more 0 out of 0 backward forward bOnline Starter bOnline Unlimited Calling bOnline Unlimited Calling Price £6 Price £13.95 Price £15.50 Find your best-suited VoIP provider Compare prices Pricing correct as of August 2023bOnline VoIP FeaturesWith a bOnline system, we think you have a high chance of avoiding extra spending as it is compatible with seven desk phone providers, whereas the average provider is compatible with an average of four. If you already have desk phones in use, it’s important to choose a system (like bOnline) that can neatly slot into your setup. Otherwise, you may spend unnecessary cash on all new phones. It's important to note that there is one notable absence on bOnline’s list of compatible phone brands: Cisco. So, if you already have Cisco phones on your premises, bOnline may not be your best choice.Unfortunately, bOnline scores rather low in terms of scalability. It lacks some key features for management purposes, such as call monitoring functions and transcription, so we think it may not be the best fit for expanding teams or startups looking to grow.Due to a lack of compliance certifications and multi-factor authentication, bOnline only scores 1/5 for security, which is the lowest on the board.You can reach bOnline customer support via phone line and live chat, but a lack of email and 24/7 availability brings its score down to an average 3/5. However, it does also provide a 99.999% uptime guarantee, which means that it's unlikely your operations will come to a halt due to a lost connection.Among its competitors, bOnline stands out when it comes to price, offering as much bang for your buck as Vonage (bOnline has fewer features, but is also cheaper, so this balances out). Here it's beaten only by GoTo, the best VoIP provider for value for money.That said, there are a few areas where bOnline is beaten by its competitors – its security features, scalability, and customer support options are all outperformed by the other providers on this list. As mentioned, bOnline could greatly improve on security, scoring only 1/5, whereas 8×8 scores full marks.Despite its shortcomings, bOnline boasts an excellent reputation among existing customers, with an average rating of 4.5/5 on consumer review sites – the second highest score in our research, beaten only by Nuacom.bOnline’s key features for businessesStarterUnlimited CallingUnlimited & VideoUnlimited domestic minutesUnlimited inbound, 100 outbound*✓✓International minutes✘✘✘Local numbers✓✓✓Ring group✘✓✓Call queues✘✓✓Video calling✘✓✓Call conferencing✘✓✓CRM integrationAvailable for £5 extra per monthAvailable for £5 extra per month✓Uptime guarantee99.9%99.9%99.9%Onboarding support✘✓✓Live customer supportLive chat and phone lineLive chat and phone lineLive chat and phone line*Inclusive minutes per user, per monthAs you can see, bOnline’s cheapest package, Starter, is really basic, offering very few of the key features we’d recommend for businesses.Really, this plan should only suit you if you’re a single person operation, have a pretty small customer base, and are just looking to set up a professional phone number. If you run a larger business, you’ll find much more value in bOnline’s pricier plans (take the word “pricier” with a pinch of salt here, because even bOnline’s most expensive plan is relatively cheap).Another thing to take note of is the fact that bOnline charges £5 per month for CRM integration on its Pay As You Go and Unlimited Calling plans. This is a pain, for sure, when other providers include ready-made CRM integrations in their packages. However, these two bOnline plans are pretty cheap to start with, so an extra fiver shouldn’t necessarily break the bank. Helpfully, bOnline can integrate with 11 different CRM systems, including Salesforce, MS Dynamics, and Hubspot. 6. Dialpad – Best business VoIP provider for conversational AI Dialpad 3.8 Pricing £12 – bespoke Get free quotes Dialpad review Why is Dialpad best for conversational AI? Dialpad’s standout feature is conversational AI. Dialpad Ai accurately transcribes phone calls in real-time, flags whether or not the conversation is negative or positive, automates post-call summaries, including highlights and action items, and enables you to create tips and advice that appear on screen when certain keywords or phrases are spoken on a call.

Another provider suitable for internationally dispersed teams, Dialpad's servers are spread across the globe. Given UK and EU privacy laws differ from that of the US, for example, if keeping your customer data under stricter privacy laws, you may want to consider a UK/EU-based company. Similar to GoTo, Dialpad provides a wealth of online help articles and gives customers the option to submit a ticket or engage in live chat for support.While it's headquartered in California, Dialpad has had a London-based office since 2019. With a globally-dispersed network of data centres, this is another provider suitable for establishing international connectivity. Dialpad is another provider that relies on online help via submitting a ticket or consulting existing help articles.Dialpad VoIP PricingDialpad’s pricing is good, earning it a reasonable score of 4/5 in our pricing analysis. Starting at £12 per user, per month, Dialpad is certainly affordable, but its plans don’t offer quite as much value for money as GoTo, Vonage, or bOnline. You should also take note of the fact that the Enterprise plan comes with custom pricing – this will be worked out on a case-by-case basis, so get in touch directly with the provider for a tailored quote.Read our full-length Dialpad review for more information.

Most helpful for businesses with sales teams, call centres, or contact centres, this tool helps your team to quickly make sense of high volumes of calls, with instant visibility over outcomes and next steps, and access to in-the-moment coaching. Dialpad includes unlimited outbound and inbound call minutes, which we think is a huge plus.When choosing a VoIP system for your business, we recommend choosing a system that can accommodate your business's growth. Dialpad only scores a 3.3/5 for scalability, meaning it lacks some key features for larger teams, such as call monitoring or integrations with other software systems. There is a ‘call-centre’ add-on that may mitigate some of these shortcomings.Dialpad can be reached via phone, live chat, and it also has a knowledge hub, which earned it a solid 4.5/5 for customer support. If you're a particular fan of email support, Dialpad may fall short here as it's not on offer. Alternatively, consider 8×8 or RingCentral, who can be contacted by email.Dialpad is definitely let down by its lack of ready-made integrations – it has the fewest of all the providers on this list, meaning there isn't seamless integration with your other software. It's also not as easy to scale as 8×8, RingCentral, Vonage, GoToConnect, or Nuacom, which can mean that you may outgrow your plan when your business expands.However, Dialpad offers a great selection of customer support channels, earning a customer support score of 4.5/5. This is only beaten only by 8×8 and RingCentral. Its variety of features is solid and, once again, 8×8 and RingCentral are the only VoIP providers that offer a comprehensive array of features. Dialpad finally one-ups the giants when it comes to price and customer satisfaction – Dialpad's prices are cheaper, and its average customer review score (4.4/5) is higher than 8×8's and RingCentral's (both 3.5).Dialpad’s key features for businessesStandardProEnterpriseUnlimited domestic minutes✓✓✓International minutes✘✘✘Local numbersOne per userOne per userOne per userRing group✓✓✓Call queues✘✓✓Video calling✓✓✓Call conferencing✓✓✓CRM integration✘✓✓Uptime guarantee✘✘100%Onboarding supportAt an additional costAt an additional costAt an additional costLive customer supportLive chat24/7 live chat and phone line24/7 live chat and phone lineDialpad’s Pro and Enterprise plans provide a lot of the important features needed by businesses, such as call queues, CRM integration and an uptime guarantee (on its Enterprise plan). Alongside GoTo and Nuacom, Dialpad is one of the only providers we analysed that offers ring group functionality on its cheapest plan, which is a nice tick in its favour.However, there are limitations worth highlighting. Firstly, ready-made CRM system integration is only available with Salesforce, Zendesk, and Hubspot, which is something to be aware of if you use another system for your customer relationship management. That said, the software does have an open API, so you may be able to create your own integration with a CRM system of your choice.While it's a necessary feature for larger businesses, it’s a little disappointing that the uptime guarantee is only included on Dialpad’s Enterprise plan. With a 100% guarantee, you can rest easy in the knowledge that your system should never go down. It’s a shame this excellent promise isn’t replicated for Standard and Pro users, who are left dreading the moment their system could suffer an outage.Finally, it’s worth pointing out that Dialpad only enables you to set up one local number per system user. If you’d like your integral team members to be contactable on a variety of numbers, this is not possible with Dialpad. If this is a priority, you should look at Central or 8×8. What's new for Dialpad? August 2023 Dialpad has introduced Ai Playbooks to track adherence to sales methodologies. Dialpad Ai can provide automatic suggestions and phrases during a call, understand if this was carried out, and then check the task off the list or notify managers if the action was not completed. 7.

User reviews can tell you the truth about a product or service, without the sugar-coating. In terms of customer satisfaction, Nuacom knocks it out of the park with the highest score yet of 4.6/5. This means users just like you had a positive experience with this phone system.

It's a ‘cloud-based' system, which means that its data is stored in various locations rather than one geographic area. Again, this may not be ideal for those businesses dealing with sensitive or private data who want to be sure that data is dealt with according to UK or EU law.Nuacom VoIP PricingAs of August 2023, Nuacom's pricing is no longer public so you'll need to contact them for an accurate quote. In our cost analysis, Nuacom was not the best VoIP provider out there for value for money. When Nuacom's prices were public, its Unlimited plan started at £14.99 per user, per month, making it he most expensive entry-level VoIP packaged we looked at. The jump up to £29.99 per user, per month on the Call Centre plan is quite a big leap to take for growing businesses that want to move onto the advanced packages. That said, Nuacom is still cheaper overall than 8×8 and RingCentral, so it earned a rather middle-of-the-road score of 3.8/5.Check out our in-depth Nuacom review.

With Unlimited, its entry-level plan, you’d expect nothing less.If you're looking to upscale your business, your phone system needs to follow suit. Nuacom receives an above-average score (3.8/5) for its scalability. It lacks security features such as compliance certifications, multi-factor authentication and secure password rules, which are important for larger teams that need to protect business and customer data.In terms of customer support, Nuacom can be reached by email or via phone, it also provides a user forum, knowledge hub, and live chat for more immediate answers to your questions.Unfortunately, overall we noticed that Nuacom provides a fairly average system. With its 3.8/5 for scalability, it's easier to scale than Dialpad and bOnline, but not as easy to scale as 8×8, RingCentral, Vonage, or GoToConnect.Nuacom only scores 3.2/5 for features as it only has a minimal offering when compared with the other top VoIP providers on this list. It lacks any collaboration features so it can't be used for in-house communication which is pretty limiting and means you'll have to rely on another system for this.That being said, a huge pro for Nuacom is that it has the best overall review score from its customers of all the UK VoIP providers we analysed. We aggregated user ratings from software review sites G2, Capterra, Trustpilot, and TrustRadius, resulting in a fantastic overall score of 4.6/5 for this VoIP provider.Nuacom’s key features for businessesUnlimitedCall centreEnterpriseUnlimited domestic minutes✓✓✓International minutes✘✘✘Local numbers✓✓✓Ring group✓✓✓Call queues✓✓OptionalVideo calling✘✘✘Call conferencing✓✓✓CRM integration✓✓OptionalUptime guaranteeOptionalOptionalOptionalOnboarding support15-minute session15-minute session15-minute sessionLive customer supportLive chat and phone lineLive chat and phone lineLive chat and phone lineWith Nuacom, you can set up ring groups and call queues even on the cheapest plan, which is generous considering that most VoIP providers only offer these features with their advanced plans (GoTo is the only other provider on this list that makes these features available straight away).On the flipside, one downfall for Nuacom is that it doesn’t come with any video conferencing capability. In fact, it doesn’t provide any unified communications features, with no sign of team messaging or document sharing tools either. Nuacom may be all about the VoIP phone technology but, nowadays, it’s reasonable for you to expect a comprehensive collaboration platform from your VoIP provider, so you don’t have to pay more to sign up to additional systems. It seems Nuacom is a little behind on this front.It’s also interesting that Nuacom’s uptime guarantees are optional. We presume they’re add-ons that you can pay extra for, or negotiate to be included in your package. What's new for Nuacom? August 2023 Nuacom has introduced mandatory call tags and notes which means agents will have to organise each call they take and ensure information is left for future calls or inquires.

How did we find the best business VoIP providers in the UK?To determine the best VoIP system on the UK market right now, we embarked on a deep dive into the top seven providers. We rigorously tested each provider against a number of criteria deemed essential when purchasing the ideal VoIP system for your needs. This includes:Pricing: a significant factor when choosing a product is whether it’s good value for money. Cheaper isn't always better, so we take a comprehensive view of factors, such as: the price itself; whether a free plan is available; and whether or not the best features are available across all plans, and not only the premium option.Features: in this category, we take a microscope to the product to gain an insight into what it actually provides and what you can actually do with the product.External Connections: it’s important to know whether a provider can seamlessly integrate into your existing business communications infrastructure.Customer Support: network connectivity can be a troublesome element to business operations, so we want to know what options are available to get you back on track when something goes wrong.Security Options: confidentiality is critical for both your clients and your business, so we looked into which internal security features were provided and how secure each provider is.Scalability: when your business grows, you want your software to accommodate this. Scalability takes into account the ease of upscaling your plan with your provider so that you don't have to make a switch later down the line.Customer Score: taking stock of what existing customers really think of the product, we looked at average scores across G2, Capterra, Trustpilot, and Trust Radius.

Its broad range of features helped it secure the top spot in our independent research, where it scores an impressive 4.7/5. How do I get a free VoIP number in the UK? Some VoIP providers will offer the first number as a free offer, only charging for additional numbers past that. Otherwise, there are services like Google Voice or FreedomPop that offer free VoIP services, though these may be rudimentary due to the lack of cost. Will VoIP work if the internet is down? This will depend on the provider, but typically VoIP services do still work if the internet fails. There are a couple of different redundancies that can be built into a VoIP system, such as resorting to conventional phone lines, or having the calls being rerouted through cell phones. Is VoIP as good as a landline? While there's no definitive winner, it's a very close race. Landlines can be slightly more reliable, especially in locations with weaker Wi-Fi presence, but VoIP phones win when it comes to scalability, cost, and long distance calls. What is the main disadvantage of VoIP? As VoIP relies on an internet connection, a spotty connection can be a real hurdle when it comes to using your VoIP phone. There can also be noticeable latency and spotty moments on the calls when compared to a conventional phone line, which can again be exacerbated by a poor internet connection. Is it worth switching to VoIP? While every company has different needs, it's probably worth switching to VoIP, especially over a long term period. While the initial investment might cost, as you're switching your entire phone system, the money you save over time will eventually prove that VoIP was worth your investment.Additionally, whether it’s worth it or not, it will soon become a mandatory switch due to UK landlines being officially phased out in 2025. Best to make the switch now while demand is lower, and therefore prices are very fair. Can I keep my phone number if I switch to VoIP? Yes! I almost every case, ruling out technical glitches, you will be able to take your phone number with you when you switch to VoIP. Why is everyone switching to VoIP? The main reasons to switch to a VoIP provider are:Increased scalability: As your business grows, new VoIP ports can be easily bought and installed with zero interruption to your business' operationsCost savings: VoIP can save your business a lot of money on phone calls, especially if you make them frequently, with some even making inter-site communication entirely freeEasier long distance calling: If you run a business with multiple sites or home workers who are frequently on the phone, VoIP will ensure easy communication as long as there is a Wi-Fi connectionDespite its numerous advantages, many are switching to VoIP now in time for the “The Big Switch Off” in 2025, when UK landlines will officially be phased out.
