A cloud-based phone system doesn't rely on traditional phone lines or physical hardware, instead, your business can use a phone system on your laptop, desktop, or smartphone.This system works by converting analogue signals into data packets which are then transmitted via the internet. Once a call has been placed, a VoIP provider routes the call appropriately. We prefer cloud phone systems to traditional phone lines as they're affordable, reliable, and flexible.Plus, with the big switch-off looming, we recommend businesses make the move before your phone line is affected. The big switch-off will happen by December 2025 and will affect businesses that are using the PSTN network. You might commonly know this as the network that connects to your landline. By this date, you'll need to have the infrastructure in place to support newer technologies such as VoIP. How can I switch cloud phone system providers?When switching from one cloud phone system to another, assess the limitations of your current provider and choose a new system that suits your business. This could include factors like call volume, number of users, features, and cost.Compare providers using our free quote comparison tool, once you've completed the form, you'll get a call back so you can ask questions and receive all the information you need before switching.You can also use our best business VoIP provider guide or look at the various providers on this page to get a better understanding of which providers are the right fit for your business.Once you've chosen the provider you want to switch to, make the most of their free trial or demo so you can test their call quality, reliability, and features.Before the switch, backup important data from your current provider.If you're switching from a cloud system to another cloud system, you might not have to change up your hardware but check this with your new provider to ensure you're fully set up for a smooth transition.If you're transitioning from a traditional landline due to the big switch off or because you want a cloud phone system, check with your provider what new hardware you will need. Because you're switching to a cloud phone system, you might actually need less hardware but you will need a strong internet connection and devices for the cloud phone system. These devices include a laptop, desktop computer, or smartphone.If you want to keep your current phone numbers, you'll have to port them to the new provider. This process can take a little time so it's important to plan ahead but your new provider will be able to assist you with this.Typically, your new phone provider can complete the switch within one working day. So, it's best to try and schedule this on your least busy day to prevent any major interruptions.

It’s been available in the UK since 2009.Over the years, 8x8 has made several strategic acquisitions to expand its portfolio.

In 2020, 8x8 acquired callstats.io, a Finnish startup that provides SaaS call quality monitoring for popular communications apps.

With a generous range of integrations, including CRM, Helpdesk, web conferencing, and external live chat, you can easily integrate 8×8 with your pre-existing software infrastructure. This will allow you to bring all of your business tools under the same umbrella and develop a great customer experience strategy.We're big fans of 8×8's recent incorporation of AI-assisted features, such as the Intelligent Customer Assistant (launched in April) and the Supervisor Workspace (launched in May). The former allows businesses to automate self-service experiences across channels; the latter acts as a interface that combines analytics, performance management, and team admin capabilities for contact centre leaders.It also is compatible with a broad range of third-party desktop phones, including Polycom, Cisco, Panasonic, and Yealink, making it a powerful and painless tool to set up. 8×8 also offers onboarding support with their Customer Success Managers, making it a top-notch option for helping new employees adapt to the communications system used by your business.The part where 8×8 does falter is in price. Its previous £10-135 pricing range led it to score 2.5/5 in this category in our research, as it was a more expensive option compared to other providers we look at. To complicate things further, the provider stopped advertising its prices in June 2023 and now only provides them through quoting. If you're looking to tighten your belt, then we'd recommend looking at bOnline or Dialpad instead, which are cheaper and have more transparent pricing.In the UK, 8×8 have office locations in London and Aylesbury so its customers can be confident that they can access a UK-based account manager within the same time zone for easier communication.

Plus, in May 2023, the providers started allowing UK customers to view their domestic rate card in the Calling Rates section under Billing of their account. Thanks to all of these great assets, RingCentral scores a 4.3/5 for features and external connections.However, we do think that RingCentral has room for improvement in its price. Scoring a 2.3/5 in this category in our research, we don't think RingCentral is the best option for businesses that are looking to save money in their next unified communications investment. If you're looking for a more affordable option, we'd recommend looking at Vonage, bOnline, or GoTo Connect, all of which score above a 4/5 for price in our research.RingCentral have an office in London which can make it easier for customers to access support from an account manager or sales rep as they'll be in the same time zone.

These features explain why over 700 customer centre customers have turned to Vonage internationally. Thanks to all of these great assets, Vonage scores a 4.4/5 overall in our research, as well as a strong 4/5 for features.However, where Vonage stumbles is with its security features. Scoring a 3/5 in this category in our research, Vonage doesn't come equipped with multi-factor authentication or password rules. If you'd like to feel reassured on the security front, we'd recommend going for 8×8 or Google Voice instead.Vonage has two London offices and while it doesn't have 24/7 customer support, you can get in touch with someone during business hours. You might like to know: Unfortunately, we can't advise on how much CX Express, CX Elevate, and Vonage Contact Centre cost. This is because Vonage doesn't share this information. Instead, it asks that you get in touch for a personalised quote. Did You Know? 40% of working adults reported having worked from home at some point between late January and early February 2023.

For as little as £10 per user, per month, it has the richest offering of international calls. It gives you access to free international calling to over 50 countries. This makes GoToConnect a fantastic option for businesses that are looking to cater to, or maintain, an international clientele. This rich call offering and its low price earns it a 4.5/5 for price. Regardless of which subscription you choose, GoToConnect gives you access to all the inbound communication features you might need, including ring groups and call queue. These features let you take on increasingly more calls, which is a great asset for scalability. Thanks to this, GoToConnect earns a 4.4/5 for scalability in our research.However, and ironically so, GoToConnect isn't the greatest at external connections. Scoring a 2.6/5 in this category in our research, you miss out on external live chat, analytics, and workspace integrations. Therefore, we don't recommend GoToConnect for businesses that already have a well-established and broad software infrastructure with lots of moving parts. If you want a puzzle piece that will fit in with all the software integrations you need, we'd recommend looking at RingCentral or 8×8. ▶ Read more: The best phone systems for small businesses What's new for GoToConnect?

How Do Cloud-Based Phones Work?Cloud-based phones use cloud servers to make and receive calls and use other phone features such as voicemail. Cloud-based phone calls are converted into data packets and transmitted over the internet. This makes cloud-based phone calls cost-effective and fast which is why they're a popular choice with businesses.Because they work over the internet, cloud phone systems often include extra features such as call forwarding, a virtual receptionist, and virtual phone numbers. Cloud Phones vs. Traditional PhonesThe main difference between cloud phones and traditional phone lines is that cloud phones work over the internet as opposed to physical phone lines. Cloud phones also don't need the hardware infrastructure, you can typically download the software onto devices such as desktop computer or laptop, as long as you have an internet connection you're good to go.Because there's less hardware and it runs over the internet, cloud-based phone systems are typically much cheaper than traditional phones. It's also much easier to scale your business up or down with a cloud phone system as the provider can quickly install and un-install the virtual phone lines.

Save by comparing free, tailored quotes from the best phone system providers for you Do you already have a cloud phone system? Yes No Just answer a few questions – it only takes a minute FAQs What is a cloud telephone system? The software in a cloud phone system is hosted in the cloud, rather than on your own servers. This means you and your team will be able to access and use the system anywhere and on any device with an internet connection. In other words, it's totally mobile, and you won't be limited to using it at your workplace. This is what makes cloud telephony so great for remote and hybrid working. How does a cloud phone work? Because a cloud phone system is hosted in the cloud, your data is stored securely on a server that you and your team can access via the internet. Therefore, any device that can access the internet – including smartphones, tablets, laptops, and IP desk phones – can be thought of as cloud phones.IP desk phones are usually plug and play, and can be easily installed with the phone system software. With other devices, such as smartphones, it's usually a case of downloading the phone system app, and then simply logging in. Is a cloud-based phone system VoIP? First of all, let's clarify what VoIP actually is. Voice over internet protocol (VoIP) is a technology that carries phone calls over the internet, rather than over traditional landlines. All cloud-based phone systems utilise VoIP tech to make calls over the internet, and so in that sense, they can also be called VoIP systems.That said, it's important to understand that not all VoIP systems are cloud based. Some can be hosted on your own servers, rather than in the cloud.Learn more in our comparison of the best VoIP providers in the UK. How much is a cloud mobile phone? This depends on which mobile phone you want, and which cloud phone system you choose. Cloud phone system prices range from £8 per user, per month to over £100 per user, per month – but you'll need to factor in the cost of the mobile phones you choose. Alternatively, you can have your employees use their personal smartphones to access the business cloud phone system when they're working remotely.
