Cloud PBX Phone System

Looking to keep costs down? But keep the HD quality, ultra reliable low-cost solution for managing your business phones in the cloud.

Best Value Hosted PBX Platform

Our low-cost 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.

If you have staff working remotely, running your phone system in the cloud is a no-brainer. Incoming & outgoing calls are routed through the company PBX system, so you can keep your costs low while giving you complete control over call management.

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.

    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.

    Transfer calls to other extensions or even different phone numbers, regardless of where you or your employees are located.
