Our methodology Verdict VoIP Provider FAQs How much do VoIP providers cost in 2024?In 2024, VoIP providers typically offer a wide range of pricing plans to suit various business needs. Generally, you can expect fees ranging from £10 to £50 per user, per month, depending on the features and quality of service you require. However, it's essential to consider additional costs and fees, such as setup fees, equipment costs, and charges for international calls.We've assessed their different offerings, highlighting the features, prices, and pros and cons of each. Here's a quick overview of what each platform provides based on each option's lowest-tiered plan:Contracts with VoIP providers usually vary in length, ranging from month-to-month agreements to multi-year contracts. Opting for a longer contract term may sometimes offer discounted rates or additional perks. When comparing pricing structures, it's essential to evaluate whether paying monthly or annually makes more financial sense for your business.Switching or porting your existing phone numbers to a VoIP system may incur additional costs, such as porting fees charged by your current provider or administrative fees from your new VoIP provider. Be sure to factor in these expenses when budgeting for your transition to a VoIP phone system.If you'd like a more specific idea of how much a VoIP phone system could cost your business, you can check out our dedicated VoIP costs page. 1. 8×8 Best for scaling businesses Startups' top pick 4.7 out of 5 Pricing 4.4 External Connections 4.5 Features 4.6 Following extensive research into the top VoIP systems, we awarded 8×8 the top score for scalability. Boasting generous feature and user limits, this is a platform that will be able to grow alongside your business. The ability to place international calls makes it an unparalleled option for global firms.💡 Which type of small business is 8×8 most suitable for?8×8 is an expert in creating VoIP phone systems for a huge array of industries – particularly those with offices abroad. 8×8's huge variety in hardware leasing options also means it can keep up with your requirements for both physical and virtual technology, making it the best scalable VoIP solution for growing small businesses.Features📲 High volume calls: Yes. 8×8 offers scalable solutions suitable for handling high call volumes with features like advanced call routing and robust infrastructure.💻 Integrations: Yes. 8×8 seamlessly integrates with software such as Salesforce, Microsoft Dynamics, and Zendesk, as well as email platforms like Microsoft Outlook and Google Workspace. It also offers CRM integrations to enhance productivity and streamline workflows.Businesses using 8×8 VoIP services can take advantage of features like auto-attendant, voicemail to email, and unlimited video conferencing – all available on the X2 plan.The X2 is particularly ideal for businesses in the early stages of growth. It permits unlimited domestic calls and call conferencing with up to 500 employees. Plus, call recording is also available for training staff on the system. Those who are looking for a unified communications platform are well serviced by every X2 package, with a mobile app available and free integrations with CRM software available.8×8 also received the top score for scalability during our research. This is an aggregated score which assesses a product's ability to scale with business growth and is based on specific features such as user limit, call queue, and local numbers.Businesses that opt for the X2 and X4 packages could also benefit from contact centre integration, which is great for small customer-centric businesses with the potential to scale. Pros: Advanced call management allows you to direct calls to the right resources during business hours. Outside of business hours, you can route calls to voicemail or to alternate resources Branded Video Conferencing lets you project a professional image to your customers. Customise the entire experience with your background of choice, your logo, and a vanity URL for your meetings Excellent security features; the 8x8 X2 plan includes multi-factor authentication, password rules, and encryption Cons: Technical support can be slow at times (according to customer reviews on G2 and Trustpilot) – so don’t expect rapid same-day response times VoIP phones and other hardware are not included in the monthly price Some users find 8x8's pricing structure to be complex, with various tiers and add-on options that can be confusing to navigate. 💰 PricingSince March 2023, 8×8 no longer shares its pricing tiers publicly. However, historical pricing data tells us that users should expect to pay around £19 per user, per month for the platform's lowest-tiered plan.That would make it one of the most expensive options on this list, and is why we only recommend 8×8 to scaling firms with large cash reserves.8×8 has five plans available for business users, encompassing the X2, X4, X6, X7, and X8 plans. SMEs are best off sticking to the low end of the scale with the X2 plan. However, if you do wish to upgrade:Teams with international clients may wish to upgrade to X4 for access to 48 marketsThe X6 plan boasts more sophisticated management featuresThe X7 plan is the best option for marketers wanting to outreach across multiple channelsSales teams will find X8 the most useful plan to access its power and auto dialer features.Having recently got rid of its microbusiness plan, 8×8 Express, the brand has also obscured its business costs for its remaining five tiers. However, we know from previous research rounds that prices will likely range from £19 per user, per month for the X2 plan, to £132 per user, per month for the X8 plan.

In January 2024, 8×8 introduced significant enhancements to its integration with Salesforce and Microsoft Dynamics, now enabling interactions via SMS and WhatsApp channels. This latest update empowers agents to seamlessly engage with customers through these popular messaging platforms directly within the 8×8 Contact Center app's chat interface.With features such as the ability to initiate SMS messages from Salesforce and Microsoft Dynamics, view customer contextual information during interactions, and automatically create detailed interaction logs, businesses can now offer enhanced customer support and streamline communication processes. 2. Vonage Best for value for money Startups' top pick 4.6 out of 5 Pricing 5 External connections 3.4 Features 4.3 Vonage might not be the cheapest provider in this list (that honour goes to rival, bOnline) but it is the best VoIP system in terms of value for money. Its customer support offering is unmatched, while a sophisticated messaging app and quick setup is ideal for companies based offline that want a phone system they don't have to work to understand.💡 Which type of small business is Vonage most suitable for?For SMEs, Vonage is best for those that want a phone system, but don’t rely on it as a main revenue stream, such as a small dentist practice. The system can’t perform as many tricks as 8×8, but as an affordable phone system without too many confusing bells and whistles, it’s a safe call.Features📲 High volume calls: Yes.Vonage provides business phone systems designed to manage high call volumes efficiently, offering features like call queuing and virtual receptionists.💻 Integrations: Yes. Vonage integrates with various business software solutions including Salesforce, Microsoft Dynamics, and Zoho CRM, as well as email platforms like Microsoft Outlook and Gmail. Its CRM integrations with platforms such as Salesforce, HubSpot, and Zendesk enable businesses to streamline customer interactions.While it might sound basic, Vonage has truly perfected its main goal of hosting and receiving calls. Its setup is quick, and its mobile app platform makes team messaging easy and effortless.UK users can also speak to helpful Vonage advisors via a user forum, online knowledge base, email, phone, and live chat. That’s why we ultimately recommend it to startups or firms without major VoIP requirements who are just after clear call quality and simple setup.Many sophisticated features are missing in the Vonage feature list. Capabilities such as setting a customisable greeting for inbound calls, aren’t available on the Basic plan. Meanwhile, virtually all advanced tools (integrations, hold music, voicemail to text) are only available for an added fee, a reflection of Vonage’s affordable pricing plans.These talents contribute to Vonage’s overall customer satisfaction score of 4 out of 5, according to our research, which beats our top contender 8×8 by half a mark. Pros: Our best score for price - Vonage is an affordable provider which won’t limit your cash flow as we head into an uncertain economic period Document sharing is available with Vonage so you can send contracts to business partners or bring up customer credentials in case of a complaint Mobile app is available for improved access - handy if you work with large sales teams that travel around the country Cons: Unlike rival software Nuacom, Vonage does not provide call recording unless you upgrade to the Professional plan Vonage doesn’t score so well for security with no multi-factor authentication or password rules, which might make it harder for customers to trust your team if based in telesales You’ll have to pay extra to facilitate a call queue, which can lead to frustration and a poor customer experience 💰 PricingPricing for Vonage's lowest-priced tier, Vonage Express, starts from £10 per user, per month. However, this does cap the number of calls you can make from your desktop. We recommend small businesses invest in Vonage Core instead, for £18 per user, per month.For those looking to upgrade, Vonage has three pricing tiers available for UK businesses. These are Vonage Core, Vonage Pro, and Vonage Max. Here's a quick run through of how they differ:Vonage Core (£18 per user, per month) has unlimited domestic calling available, best for teams with more than one sales repVonage Pro (£20 per user, per month) is best for managers, with call recording and call monitoring availableVonage Max (£25 per user, per month) is best for marketers, with CRM integrations availableWith prices starting from just £10 per user, per month and rising to £25 for Vonage Max, Vonage is cheaper than 8×8 and also more transparent with its upfront costs than the latter. However, Vonage does come with a significant number of hidden fees.

In January 2024, Vonage released some interesting new upgrades and improvements to its phone service.One of them is Noise Suppression, which helps reduce background noise during calls on mobile phones, making it easier to hear the person you're talking to. They also added options so you can choose whether or not to use this feature during calls.Plus, they made it possible to get more detailed info about your calls, like whether the call is working properly. 3. bOnline Best for running a service desk Startups' top pick 4.4 out of 5 Pricing 5 External Connections 3.6 Features 4.5 bOnline is the ultimate option for service desks. It allows an unlimited number of inbound calls for just £6.50 per user, per month. Easily the cheapest provider on this list, we recommend it to companies that get a lot of customer enquiries, such as small IT helpdesks.💡 Which type of small business is bOnline most suitable for?bOnline is built specifically for smaller helpdesk operations. In the larger picture of telecoms companies, it doesn’t have the operational capacity and technical ability of 8×8 or RingCentral. But its low-cost Starter plan makes it an excellent choice for SMEs wanting to accept customer calls, not make them.Features📲 High volume calls: It depends. bOnline offers phone services tailored for small businesses, but the scalability for handling high call volumes may vary based on specific needs and package options.💻 Integrations: Yes. bOnline integrates with Microsoft Office 365, G Suite, and Slack for software solutions, along with email platforms such as Microsoft Outlook and Gmail. Its CRM integrations with Zoho CRM and HubSpot CRM facilitate improved sales and marketing processes.So, what makes bOnline so great? Well, its lowest-priced tier (bOnline Starter) is decidedly generous. It offers 50+ features – including unlimited calling, a reporting dashboard, a digital phone line, and a mobile app. You’ll also be able to try out the service free for 30 days.The reporting dashboard is a unique bOnline feature that some providers don’t offer, or offer only on a premium plan (which isn’t cost effective for small businesses). It uses infographics and processes real-time data, so you can interpret insights and make business decisions based on call volumes and durations.You can also use preset call flows to customise call flows to your business, directing customers through the appropriate contact channels. This feature is especially handy if you don’t have an existing PBX system, auto-attendant, or receptionist.You can set up the bOnline VoIP hosted system in just two minutes, with no engineers, installations, or IT buffs required. Plus, bOnline is one of the first providers to start selling broadband on top of its virtual phone system. This means you have the option to bundle your digital phone line, calls, and broadband.💰 PricingbOnline pricing starts from £7 per user, per month. With this, you'll get unlimited inbound calls but you'll only be able to make 100 minutes of calls per month. Users can upgrade to the bOnline Unlimited Calling plan for £13.75 per user, per month, to get around this.It's worth nothing that bOnline is not as generous as 8×8 when it comes to call features. Many of these are only available as add-ons for an extra fee. For example, you'll need to pay an extra £5 per month for CRM integration, call recording, and HD video conferencing.International calling is also paid-for, but it's still very cheap. £6 +VAT per month will get you 500 minutes to 100 destinations.Unlike 8×8, bOnline is not the most scalable option on the market. SMEs can choose from just three plans: bOnline Starter and bOnline Unlimited Calling (£13.95 per user, per month). There is also the option to purchase bOnline Unlimited Calling with a physical desk phone included for an additional £1.55 per user, per month.Put simply, the main reason to upgrade to bOnline Unlimited Calling is to access more outbound minutes. Whereas bOnline Starter gives you just 100 minutes of outbound calls, bOnline Unlimited is, as the name suggests, uncapped.That makes it an easy decision on whether you need to upgrade. If you need to contact customers for more than one hour and 40 minutes per month, upgrade. If not, stick to bOnline Starter. Luckily, both plans are still cheap and cheerful, with bOnline Unlimited costing just £6.95 more than the Starter plan. Pros: Free 30-day trial so you can see what the service has to offer Insightful, easy-to-interpret reporting dashboard to help you identify call trends Provides the option to bundle a VoIP phone as part of the bOnline Unlimited Calling plan Brilliant customer service – it’s the only micro business-focused telecoms company rated ‘Excellent’ on Trustpilot Cons: Not suitable for outreach and contacting new clients as several key features - custom call lists, auto dialer, and predictive dialling - are all unavailable.

In August 2023, bOnline introduced significant enhancements to its customer service offerings, focusing on improving first call resolution and streamlining the caller experience with a simplified IVR system. Recognising the frustration of being transferred between departments, bOnline invested in training and upskilling its customer service team to ensure that callers' issues are resolved quickly and efficiently by the first point of contact.This initiative was further supported by consolidating provisioning, porting, and migration teams into a single unit, enabling all team members to possess a broader knowledge base and address a wider range of customer queries. Additionally, bOnline implemented a new Interactive Voice Response (IVR) system, providing callers with clear options and navigation pathways to direct their calls effectively. 4. Dialpad Best for onboarding new sales reps Startups' top pick 4.4 out of 5 Pricing 4.7 Features 2.4 External connections 4.7 Sales is a tough industry to master. Luckily, Dialpad's extensive onboarding and recording tools make it ideal for new starter orientation. Helpful features like call recording can help new starters understand the sales script and identify ways for improvement – bringing both HR and business benefits.💡 Which type of small business is Dialpad most suitable for?Dialpad takes the crown for coaching and training. For an added fee, Dialpad offers live call coaching allows managers to listen in on calls and take over when needed, providing real-time coaching and sales recommendations.Features📲 High volume calls: Yes. Dialpad's cloud-based communication platform is equipped to handle high call volumes effectively, with features such as AI-powered call routing and analytics.💻 Integrations: Yes. Dialpad integrates with G Suite, Microsoft Office 365, and Slack for software solutions, as well as email platforms like Gmail and Microsoft Outlook. Its CRM integrations with Salesforce, HubSpot, and Zendesk empower businesses to centralise customer data.When we talk about software innovation, we mean the fact that Dialpad’s entire cloud-based platform is powered by AI. The voice intelligence software that comes with Dialpad captures action items, provides coaching, takes notes and even analyses sentiments in real time whilst you are on a call.This voice intelligence is great for call centre managers or sales managers, who, using the VI Call Summary feature, can quickly find specific “coachable moments” on which to focus their attention when providing performance feedback.Dialpad comes with all the standard call management features, plus integrations with helpful apps like Slack, G Suite, and Office 365. It also comes with a 14-day free trial, which is useful if you just want to sample what’s on offer.What lets Dialpad down is its reporting, which lags way behind competitors – although this provider is currently adding more features and working on improvements. Unlike 8×8, RingCentral and bOnline, you can’t analyse the quality of calls with Dialpad, nor schedule reports for future release. Instead, you’ll just have the option to print or export old reports in a CSV format – which is a fiddly delimited text file exported into excel. Pros: The user experience is really good, and switching from devices (like mobile to desktop) is easier to do than with competitors like 8x8 The voice intelligence software is incredibly useful in providing feedback and highlighting weaknesses or pain points for employees during calls with customers – perfect for a sales-focused business Live call coaching is an excellent addition, which competitors only offer in premium plans Cons: Reporting and analytics are basic and lack customisable features, which isn’t great for businesses needing to measure their quality of service The standard plan is more expensive than other competitors Integrations (besides Microsoft and G Suite) and 24/7 customer support are not available with the standard plan – support is only available five days per week 💰 PricingWith prices starting from just £18 per user, per month, Dialpad affords you with unlimited calling and video calling – a premium offering that outpaces rivals like Vonage. However, it is very limited for software integrations, which could be an issue for those looking to scale their operations.Dialpad offers two plans to small business users: Dialpad Standard (£18 per user, per month) and Dialpad Pro (£28 per user, per month). There is also an Enterprise option (which we wouldn't recommend to SMEs) which provides priority agent support to global corporations.The Standard plan is a great foundation for SMEs to begin with. Teams of 20+ and based in multiple locations may want to upgrade to the Pro plan to avoid any allowance caps on the Dialpad Standard plan.While the Pro plan may cost more, it will also make your team considerably more productive with the ability to attach multiple phone numbers per account and create up to 25 ring groups.

In February 2024, Dialpad introduced a significant update to its platform with the addition of a Contact Center agent availability setting.This feature empowers Contact Center administrators to toggle the agents' capability to set themselves as unavailable within their contact centre.By providing this level of control, Dialpad aims to enhance operational efficiency and streamline workforce management within contact centre environments. This new functionality ensures administrators have greater oversight and flexibility in managing agent availability, ultimately leading to improved customer service and satisfaction levels. 5. GoTo Best for remote teams Startups' top pick 4.3 out of 5 Pricing 4.4 Features 3 External Connections 4.2 GoTo's huge library of feature has all the tricks needed to help remote-based sales reps connect with colleagues and customers. Crucially, GoTo Basic can route calls to multiple phones, so you or someone on your team is always in reach. That way, you can handle large volumes of customer enquiries without having to port your phone number.💡 Which type of small business is GoTo most suitable for?For those firms spread across the country and needing to constantly communicate – for example, construction companies – GoTo is a flexible VoIP provider that can be used across all devices. It is the only option on our list to offer unlimited call conferencing and video call features for no more than £10 per user.Features📲 High volume calls: No. While GoTo offers conferencing and collaboration tools, its phone system may not be specifically optimised for handling high call volumes in the same way as other providers.💻 Integrations: Yes. GoTo seamlessly integrates with Microsoft Teams, Slack, and Google Calendar for software solutions, along with email platforms such as Microsoft Outlook and Gmail. Its CRM integrations with Salesforce, HubSpot, and Zendesk enable businesses to streamline customer interactions.GoTo is a cloud-based VoIP system that can be accessed by pretty much any device, so you can make calls from both your desktop and smartphone. It also bundles SMS and video calling as part of its package deal.Supporting over 180 different models of desktop phones and conference room systems, GoTo is the ideal VoIP solution for internal comms. The lowest-priced plan, GoTo Basic offers advanced call conferencing for up to 150 attendees to keep remote workers connected including unlimited meeting hours, screen sharing, and breakout rooms.Enterprise-grade security is a big perk of GoTo. Users can create virtual meetings knowing that nobody will be turning up uninvited to hijack your conferences or leak your video link. You can also join meetings securely from any device thanks to GoTo's flexible mobile application.Priced at just £11 per user per month, the GoTo Basic plan is an affordable option for SMEs. However, with a specialty for businesses operating in remote locations, it is best for those with larger teams, such as 20+, rather than small or microbusinesses. Pros: GoTo gets a customer score of 4.4 out of 5; the second-highest score in our list and beating the top VoIP contender, 8x8. The premium plan has several different modes for supervisors to monitor calls including Spy Mode to monitor an existing conversation without being heard. Even the Basic plan has spam prevention to screen and block fake calls - bOnline does not have this feature available. Cons: Doesn’t come with its own storage space for your recorded calls, unlike Dialpad. You’ll need to purchase and connect a third-party cloud storage service. Focus on internal comms means GoTo is not great for selling and outreach 💰 PricingGoTo Basic pricing starts from £11 per user, per month. For this fee, you'll get a wealth of call features (predominantly video), certainly enough to satisfy SME customers.As with Dialpad, GoTo users can choose between two payment plans: GoTo Professional (£11 per user, per month) and GoTo Business (£15 per user, per month). With both plans, you'll be able to make an unlimited number of domestic calls, plus the option to add a toll-free business number for your customers' convenience.The main difference between the two plans is in their average user size, however. GoTo Standard boasts some advanced features that will make life much easier for large teams, like the ability to create an unlimited number of ring groups. This benefit won't mean as much to smaller firms receiving fewer inbound calls.

In February 2024, GoTo introduced several enhancements to its platform, aimed at improving callback functionality and reporting capabilities.The latest update includes callback reporting improvements, allowing supervisors to gain insights into callback activity in the Queue caller board. With new global filters for callback offered and callback requested, supervisors can better understand caller interactions and preferences while in the queue. Additionally, a new Callback Requests widget has been introduced, categorising callbacks based on their status, whether pending, handled, or evicted.Furthermore, users now have the added capability to print Queue caller charts to PDF, enhancing accessibility and document sharing within the platform. These updates are designed to streamline operations and provide users with more comprehensive tools for managing customer interactions effectively. 6. RingCentral Best for business mobile use Startups' top pick 4 out of 5 Pricing 2.9 Features 4.5 External connections 5 RingCentral is the best VoIP system for companies that use business mobile phones for the majority of their operations. It is not the most sophisticated option, but its easy-to-use mobile application allows sales reps to manage calls, voicemails, faxes, and texts using a unified app without all the bells and whistles.💡 Which type of small business is RingCentral most suitable for?We most recommend RingCentral to companies that do most of their business over mobile phone. The platform works brilliantly as a mobile app, available on both iOS and Android. RingCentral users can make and receive calls, faxes, and texts; all with a gentle learning curve that won't require lots of desk training.Read our RingCentral review for more.Features📲 High volume calls: Yes. RingCentral is known for its scalability and can accommodate high call volumes with features like auto-attendant and call queuing, making it suitable for businesses of various sizes.💻 Integrations: Yes. RingCentral integrates with Salesforce, Microsoft Office 365, and Google Workspace for software solutions, as well as email platforms like Microsoft Outlook and Gmail, as well as CRM integrations with Salesforce, HubSpot, and Zendesk.Features on the standard RingCentral Essentials plan include call management (auto-attendant), high-definition voice, and quality of service reports that are great for measuring employee performance. 24/7 customer support is included with all four plans, and the premium plan even comes with a dedicated account manager.RingCentral Essentials comes with all your basic, core inbound comms features like the ability to create a customisable greeting, take voicemails, and add a virtual receptionist. It even has spam prevention, to flag any suspect callers you feel might be bad actors.However, despite RingCentral boasting 24/7 support on all of its plans, customer satisfaction levels are relatively low on review sites like Trustpilot, as technical support isn’t the best and resolution times are often slow.But that's only if you can't grasp the app and we'd be surprised if learning curve was even an issue. RingCentral's easy-to-use interface and simple functionality means you won’t need much support anyway. Pros: Super easy to get to grips with; great for brick-and-mortar businesses Supports a wide range of desktop VoIP phones from vendors such as Cisco, Polycom, and Yealink if you’ve already got handsets Solid security features; RingCentral offers multi-factor authentication and has five compliance certificates at every pricing tier Cons: RingCentral Essentials package is very stripped back feature-wise, and doesn’t include unlimited audio and video meetings Customer support isn’t great – long resolution times for some technical issues 💰 PricingRingCentral has three plans available to business users: RingCentral Standard, RingCentral Premium, and RingCentral Ultimate. It does have a smaller plan called RingCentral Essentials, but we don't believe it would be relevant or useful to small business owners due to its very limited capacity. Here's how each plan differs:RingCentral Standard (£23.99 per user, per month): best for teams of 10+ needing an internal collaboration toolRingCentral Premium (£28.99 per user, per month): best for sales teams, with 2,000 inclusive minutes permittedRingCentral Ultimate (£33.99 per user, per month): best for security, offering both device status reports and alerts What's new for RingCentral? In February 2024, RingCentral introduced several enhancements to its platform aimed at improving administrative controls and webinar functionality. Administrators now have the capability to provision Audiocodes units more efficiently, expanding device assignments to new countries such as Australia and Germany.Additionally, admins gained greater control over app integrations, allowing them to limit access to certain integrations like Calendar, Contacts, and File Share for all users within the account. On the webinar front, hosts gained the ability to grant speaking privileges to attendees, enhancing collaboration during webinar sessions.Furthermore, the Rooms feature now supports text formatting in webinar descriptions, providing users with more flexibility in customising their webinar content.Lastly, users can seamlessly join Microsoft Teams meetings directly from Rooms, further integrating different communication tools into one unified experience.

Nuacom Best for online microbusinesses Startups' top pick 3.9 out of 5 Pricing 4.3 Features 3 External connections 2.8 Nuacom's unique feature list is tailor-made for small ecommerce sellers with two employees. If you're running the business as a side hustle, Nuacom will act as your virtual assistant, ensuring all customer needs are met, and updating you of anything that requires your attention when you can give it.💡 Which type of small business is Nuacom most suitable for?We recommend Nuacom to sales-focused businesses based online and in need of a VoIP system that gives them lots of customer insights to play with. For example, ecommerce firms. Its automation features are very sophisticated, although its opaque pricing plans make it difficult to judge whether it is the most suitable option for your budget.Features📲 High volume calls: It depends. Nuacom Unlimited offers flexible VoIP solutions, but the ability to handle high call volumes may depend on the specific plan and configuration chosen by the business.💻 Integrations: Yes. Integrates with Microsoft Teams, Slack, and Trello for communication and collaboration, supports Microsoft Outlook and Gmail for email management, and offers integrations with platforms such as Salesforce, HubSpot, and Zendesk for CRM – as well as their own recruitment integration named BULLHORN, which was released in October 2023.Nuacom, without doubt, excels at inbound communication. Its feature list enables functions like customisable greetings, voicemails, and customisable hold music to keep callers entertained in case of a long wait time.The brand's virtual receptionist can direct callers based on their inputted responses. For small business owners, who are often time-stretched and low on resources, this is a must-have tool. Virtual assistants dramatically reduce time-consuming admin tasks without comprising customer interaction – important for brand engagement.Nuacom's call recording feature also lets businesses capture and review customer interactions, providing valuable insights for training, quality control, and dispute resolution. Call analytics provide detailed data on call volume, agent performance, and customer trends, enabling businesses to optimise their operations.Still, team management tools, such as collaborative features and instant messaging, don’t fall under Nuacom’s remit. It’s also not great at returning calls. Unlike 8×8, Nuacom does not have an external video call function, and does not permit power or predictive dialling on any plan. It’s better for responding to customers, rather than outreach. Pros: Integrates with HubSpot to enable new lead generation and customer outreach Excellent customer score of 4.6 out of 5 (beating 8x8) due to the many channels of communication for help and support Huge range of inbound comms features means Nuacom copes well with customer enquiries, helpful for those based entirely online Cons: Minimum of two users permitted on any pricing plan, which means Nuacom is unsuitable (and too expensive) for micro-businesses or sole traders Nuacom does not have any compliance certificates and scores very poorly in our research for security Not recommended for team-working - collaborative features are thin with no internal messaging function 💰 PricingLike 8×8, Nuacom has recently hidden its pricing tiers. Small businesses must contact the platform directly for a quote. However, historical pricing data tells us you can expect to pay around £14.99 per user, per month for Nuacom.Nuacom has two pricing plans available: Nuacom Unlimited and Nuacom Enterprise. We recommend Nuacom Unlimited exclusively to SMEs. It includes all the essentials SMEs need to manage their calls (unlimited domestic calling, call recording, and CRM integration) and even has AI capability to help automate fiddly call admin tasks.The Enterprise plan, as its name would suggest, is a more advanced VoIP solution that is designed for larger firms with more complex needs. It offers a wider range of features, but none of these are fundamental enough to tempt a small business owner.

The platform also introduced a “Log Call Button” feature, allowing users to push data to selected, all, or none, streamlining call logging processes. Why use VoIP?VoIP is a complex business technology. It isn't something you can just take out of the box without prior research – particularly with the current pressures on business cash flow.On top of pricing, users also need to consider factors like security features, call policy management, and network strength to find a system with real value for money. That's why the most important thing when choosing a VoIP provider is to find one that offers the right level of support getting you set up and your team onboarded.1. VoIP calls are cheaperAs they use the internet instead of traditional phone lines, it tends to be that your broadband bill will cover your VoIP calls – as opposed to traditional calls, which are charged separately and by the minute.The result of this is that VoIP calling can save your business a fair amount of money – especially if your staff tend to make long phone calls, or regularly need to contact people overseas.2. VoIP eliminates the need for multiple phone linesWith VoIP, your staff will be able to make calls at the same time, in the same office, without the need to install multiple phone lines – which might otherwise be a huge drain on your money and time.3. VoIP call quality depends on your internet connectionIf you’ve got a reliable internet connection, the quality of the calls you partake in will be a lot better – think clearer sound quality and fewer interruptions or failures – than it would be if you were calling in the traditional way. What type of business is VoIP suitable for?Due to its flexibility and efficiency, VoIP is an ideal choice for many businesses. However, it’s likely to be a particularly suitable solution for businesses with the following requirements:1. Businesses that make international calls. Whether it’s using the same network to make essentially free calls across the internet, or signing up to a package which includes a set number of international minutes, VoIP offers a cost-effective and easy solution for startups who make a lot of overseas calls.2. Businesses with limited space. VoIP phones offer a virtual service, meaning there’s no need to worry about the space required to install and house traditional, physical phone lines.3. Businesses looking for scalability. If you predict that your business will grow beyond its current phone service requirements, VoIP offers an easily changeable service. Or, if you know your startup experiences more (or less) demand on its phone services at certain times of the year, it’s easy to increase or decrease the number of lines virtually. Buying guide: how to choose the best VoIP systemTraditional phone lines will be eradicated by the end of December 2025. As the UK business landscape shifts towards a digital-first approach, VoIP (or Voice over Internet Protocol) has emerged as the clear choice for businesses seeking to modernise their communication infrastructure.With VoIP, firms get crystal-clear voice quality, seamless integration with business tools, and lots of advanced features such as call forwarding, video conferencing, and mobile extensions. That's not to mention the cost savings enjoyed by eliminating expensive landline charges and international call fees.But whether you're making the switch to VoIP, or just looking for a new provider, you need to tread carefully. The imperative to move away from landlines means competition is fierce, with many new brands popping up to pedal big promises.We’ve put together five key points to consider that will help you navigate the decision-making process when it comes to switching to VoIP.🤔 1. Consider the most important features you’ll needThe most crucial aspect of any software decision is features. This is where most providers distinguish themselves with specific niches, so you need to ensure that the brand you sign with isn't missing any must-have perks. Marketing firms wouldn't need the ability to create a call queue as much as a service desk would, for example.Support is an important aspect here that is often ignored. If you're hiring new staff members who aren't familiar with the system, how can they access assistance? Think about the time zone that support agents are located in, and how you can contact them e.g. phone, email, live chat. You may want additional features such as call screening to ensure that only priority calls come through.💰 2. Evaluate your budgetYour budget will affect which providers you can choose from, as each has a different price point. However, this does not necessarily mean cheapest = best. SMEs that don't need to place a lot of calls should invest in a low-priced tier, but larger firms may need to spend more to access bigger feature allowances.Think also about hidden fees. bOnline is cheaper on first-glance, for example, but it also charges an additional £5 fee for international calling and CRM integration – two benefits that 8×8 offers as part of its X2 plan.☎️ 3. Choose between an on-premise or hosted solutionChoosing either an on-premise or hosted VoIP solution will impact communication efficiency, flexibility, and cost-effectiveness, and there are pros and cons to each.On-premise VoIP solutions are more expensive than cloud-based VoIP solutions, and usually require either an in-house or outsourced IT team for maintenance – but, they can design you a phone system that fits your exact requirements – meaning they're great for niche communication setups. And because you have your own dedicated server, on-premise solutions are even more secure than cloud-based shared server solutions.Hosted VoIP solutions offer lower upfront costs and reduced maintenance responsibilities since the service provider manages the infrastructure remotely, which makes them particularly appealing for businesses with limited IT resources or budget constraints. Additionally, hosted VoIP solutions often provide automatic updates and scalability, allowing businesses to easily adapt to changing needs without the hassle of managing hardware or software upgrades. However, reliance on a third-party service provider means businesses have less control over the system's customisation, and may be subject to potential service disruptions or downtime if there are issues with the provider's network or servers.📏 4. Think about contract lengthToday's economy is prone to certain downturns or upswings that can play havoc with SME cash flow. In this kind of inflationary environment, be sure to consider the length of time of contracts with providers to ensure you can afford to make the payments you have committed to.For example, are you happy to be tied into a contract for 24 months? Or do you want a lot more flexibility? bOnline sells its services on a pay-as-you-go basis, while other providers like GoTo ask for a minimum 12-month commitment.🌎 5. Remember your customersAn obvious tip is to think about not just where your business is based, but where your customers are based. If you need to sell to clients in Europe but choose a provider like Vonage, which does not permit any international calls to be made from any of its pricing tiers, you will end up shooting yourself in the foot.Consider also how your customers are contacting you. It might be a good idea to offer a toll-free number (free for the caller) to improve the customer experience if you are operating in the service industry, for example.📱 6. Audit your communication channelsMost companies now contact their clients via several mediums, not just over the phone. The good thing about using cloud-based VoIP software to manage comms is it can be integrated with CRM or sales software, helping to keep all of your call data and operations in one place.Internal usage is another factor. Most employees now use their phones on the go, such as when working from home. Does the phone provider you've picked have a mobile app they can use on their own devices? Is it best for sales reps, or are there admin tools as well? These are all things to consider when purchasing a VoIP system. VoIP phone systems explainedAs your business grows and you hire more staff, you’ll need to make sure your telephone systems are suitably equipped to cater to your needs.Generally speaking, there are three basic types of office phone systems: multiline, private branch exchange (PBX), and VoIP. Below, we’ve explained each type of office phone in greater detail.Keep in mind that by the end of 2025, all companies will need to switch to an VoIP phone system as a result of the Big Switch Off. The current Public Service Telephone Network (PSTN) will be closed down, and all landlines will be phased out in the UK.How do VoIP phone systems work?VoIP office telephones are the most modern, most popular office IP phone systems on the market. Using your business’s internet connection to host calls rather than traditional analog signals, VoIP allows for both video and voice chat.VoIP systems also:Require very little hardware (a desktop VoIP phone connects to the internet with just an ethernet cable)Can be managed via an app from your providerAre very cheap for calls – even international – once your broadband or mobile data plans are paid forAllow you to make calls to remote staff members via their notebook PCs, tablets, or mobile phones.If your business requires a telephone service in an emergency, a combined PBX and VoIP system could be an option – indeed, should you use VoIP on its own, any loss in internet connection could render your phones useless.VoIP systems come into three different formats: hardware-based, software-based, or ATAs. We explain what each one means below.1. Hardware-based VoIP phonesA hardware-based VoIP phone transmits calls over the internet by connecting to a VoIP server. They can do this in one of three ways:Using an Ethernet connector. These VoIP phones plug into the Ethernet port on a router, enabling them to connect directly to a VoIP server. This is the most popular and widely-used type of hardware-based VoIP phone.Using a built-in modem. These phones have a built-in modem that can connect to a VoIP server remotely – meaning they don’t require a broadband connection.Using WiFi. These phones have built-in WiFi transceivers which can connect to a WiFi access point, and in turn the internet. Some of these phones also come with Ethernet ports.2. Software-based VoIP phonesAll that’s needed to get a softphone up and running is the correct software.There’s plenty of dedicated VoIP software out there, such as:VonageJive Voice8×8’s Virtual OfficeRingCentralIf you’re installing your softphone onto your computer, you can make calls using the computer’s built-in microphone and speakers.However, if you’d prefer better sound quality and more privacy – which is especially important if you’re looking to kit out your small business’ office with multiple softphones for your staff to use – you should look to get headsets with microphones.If you’re interested in VoIP for personal use, or would like your staff to remain on the ball while on the go, it’s worth knowing that plenty of common smartphone apps can also act as softphones.Alongside their instant messaging and/or video chatting capabilities, the following apps all have an internet-based calling function:SkypeWhatsAppFacebook MessengerApple’s FaceTimeViberLineUsually, you’ll only be able to VoIP call someone who also has the app you’re using. Some apps do enable you to call a normal landline or mobile number, although this may cost you extra.It’s worth noting that some landline providers have also created apps that allow you to make VoIP calls, such as BT’s SmartTalk and TalkTalk’s Talk2Go.The key thing to remember here is that while using these apps to make VoIP calls, it’s a good idea to be connected to WiFi – unless you don’t mind them eating into your data allowance.3. ATAsInstead of getting VoIP phones themselves, it’s possible to keep your conventional phones and use an ATA – or analogue telephone adapter – to transform them into VoIP phones.ATAs take the analogue signal from your phone and convert it into digital data. The ATA also connects your phone to the internet, so the digital data can be transmitted over it.Instead of plugging your phone into a wall socket, simply plug it into your ATA and you’re good to go. Will my VoIP provider supply phone handsets?Not every VoIP service provider can supply VoIP phone handsets. Having to spend extra on finding this hardware yourself can be a pain, especially when you’re already spending a lot of money per user for the software itself. Depending on your business needs, you’ll want to check this before purchasing.Always research each VoIP software provider first, as you’ll often find the software is only compatible with certain VoIP phone models. Once you've chosen the right software, you'll be able to work with your provider to find compatible VoIP phones that match the needs of your business.Most VoIP providers offer you the option to lease your handsets (great for upgrading) or purchase them outright (more cost-effective in the long run). If not, there are lots of VoIP handset providers out there you can purchase from directly.Some of the best VoIP phones are made by Grandstream, Yealink, and Cisco. Check out our best phone system for small business review to learn more about specific VoIP handsets.

VoIP Phone Provider FAQs Can a VoIP phone be used anywhere? As long as you have an internet connection, VoIP phones can be used literally anywhere. Regardless of if you are working remotely, or in the office. This is in contrast to traditional landlines business phone services - which tie employees to their office desks in order to take or make business calls. Which VoIP provider is best for businesses in the sales sector? Even though bOnline is rated our top VoIP phone provider overall, when it comes to sales focused businesses we would suggest using Dialpad. Dialpad has the highest number of features tailored specifically to help businesses in sales . This includes call coaching and training for sales managers and integrations with apps like Salesforce. Which VoIP provider has the cheapest plan? Although not all of the providers on our list are transparent with pricing, we are confident that bOnline is the cheapest provider available to small businesses. Its pay-as-you-go plan is only £6 per user per month. What is the difference between VoIP and a virtual landline? VoIP (Voice Over Internet Protocol), is similar to a virtual landline since it also uses the internet, but it offers more sophisticated features. With VoIP, you can make and receive more calls, and come with additional features like auto attendant and call management. Do I need to buy hardware to use a VoIP system? If you are using a software-based VoIP phone (a softphone), you do not need to buy additional hardware if you have an existing computer. However, if you’re making calls from a computer, you’ll need to make sure it has a built-in microphone and speakers. If you want to ensure good sound quality on your calls, you may want to purchase a headset. If you are using hardware-based VoIP phones, some VoIP providers will supply you with phone handsets (either purchased or leased) so it’s a good idea to check with them, especially since not all handsets will be compatible with their software. How much does a VoIP system cost? Costs can vary, and overall cost involves both hardware and software. A VoIP package can cost between £5 to £40 per month. Other costs include but aren’t limited to: VoIP hardware like phones and headsets (£50 to £500), and broadband/internet (£15 to £50 per month). We have a whole article that breaks down VoIP phone costs if you want more information. What is auto-attendant in VoIP? Auto-attendant is an automated answering service. Incoming calls are answered and transferred to the right person. In many cases, an auto-attendant will use a menu system (in which callers punch in a number in response to prompts) to direct callers to the right person. Startups.co.uk is reader-supported.
