 Get the UK’s best cloud-hosted PBX phone system

Run your business phones in the cloud without any fuss

The UK’s No.1 Cloud Hosted PBX Platform

Our industry-leading Cloud PBX phone system uses your existing internet connection to make and receive calls. This means you don’t need to pay BT for a new phone number or line rental.

Running your phone system in the cloud is a no-brainer. You get much cheaper call rates, plus complete control over the way you handle your business calls.


Cloud Phone System Features

“Out-of-the-box” cloud phone system

Our standard Hosted PBX package includes everything you need to run your phone system in the “cloud” through your internet or mobile data connection.

Make & receive calls using either an IP phone or PC softphone, or via your mobile phone using our Luna app (iOS and Android).

Don’t pay for stuff you won’t use

Unlike other Hosted PBX providers we won’t charge you for features you won’t use.

But, as your business grows, you might want to add more advanced call management capabilities to your platform. Our suite of Hosted PBX features can be bolted on as and when you need them. So you only pay for what you’re using at any one time.

Make PBX “Cloud” Calls On Your Mobile Phone

Make Mobile Calls With Your Hosted PBX

Use your mobile phone to make and receive PBX calls on your Numbergroup PBX account.

Our “Luna PBX” app allows you to make and receive PBX calls via your mobile phone easily and securely without requiring any username or password. Once connected, your PBX users can:

  • Make and receive calls on your mobile handset using HD quality voice.

  • Put callers on hold and transfer them to colleagues, groups or conferences.

  • Automatically record calls to meet regulatory requirements.

  • Have outgoing calls appear from their extension’s phone number.

Performance & Security Features

Our “Luna PBX” client utilises push technology so can run in the background without affecting battery performance. Wi-Fi or 3G connectivity is required to make and receive calls.

All calls are encrypted on our platform for security, and only customers are able to access their recordings.

To add an extension, simply scan a QR code given out from our portal using the phone’s camera. Administrators can download these QR codes and send them to users via email.

Questions About Our Cloud-Hosted PBX Platform


“Our switch to Numbergroup saved us over £800 a year!”

“We’ve been using Numbergroup’s cloud hosted communication platform since 2016. Their cloud phone system is reliable and easy to use, plus they have extremely competitive call rates, friendly customer service and faultless support. Our switch to Numbergroup saved us over £800 a year! We highly recommend Numbergroup to all our business partners and clients.
James Lester, Carpet Bright UK

It’s been almost a year since we started using Numbergroup’s cloud services. Since the start they’ve made our lives easier by providing proper solutions, not just work-arounds. We’re in the recruitment business and telephone communication is the backbone of our business. I can’t say enough how relieved I am for choosing VoIP services from Numbergroup.

Dharmendra Tirdia, Ethos HR Management

Numbergroup offer an amazing service. When I first joined, it was obvious from the start that this was going to be an entirely different experience than what I had with my previous telecom provider. The technical side of things is easy, even for a technophobe like me. The customer service is first class and the value for money equals the service.

Bill Fawcett, Sole Trader

The Numbergroup staff involved were always on the ball, and always there when you needed assistance. If they weren’t available, they would call back promptly. They are polite and helpful at all times. They also have a great, flexible choice of numbers to choose from, even International, which is important for us.

Michael Christian, Homepride Marketing Ltd

We’ve been with Numbergroup for nine years now. We switched over from an on-premise phone system, which is something we’d put off for years. When we did eventually make the move, the Numbergroup support team were really helpful. They made the process a lot easier than we anticipated, and we were up and running without any call downtime.

Simon Evans, EvSol Products
We have been working with Numbergroup for over 3 years now and use their UK numbers service, termination and origination, and number porting. They make processes that can be complex, simple, and deal with any issues promptly. We have been very happy with the quality of service and support and they are a great team to work with.
Samantha Peach, Wholesale Customer

From initially assessing our current spend with our existing supplier (and actually saving us money), to acquiring dedicated telephone numbers and porting, right through to handset installation and customer support, Numbergroup have been fantastic, and delivered on all fronts. A brilliant company to deal with, nothing ever seemed too much trouble, holding our hand throughout the whole installation and training process so we understood everything first time.
