3CX is an open-platform, software phone system that works with a variety of IP desk phones, soft phones or mobile devices. Calls are made and received via SIP trunks that are delivered over your internet connection.

It provides all the features and functions of on-premises phone systems and more…. without the need to purchase the expensive hardware. You have complete freedom of where to install your PBX and which IP phones to use.

At a time of major budgetary constraints in the Education Sector, 3CX can massively cost in. UK calls are free and the commercial model is based on the number of simultaneous calls rather than a per user/seat charge. So in a School environment, where you may have many phones around campus but with limited use, there is the potential to save many thousands of pounds.



You can run the 3CX system on an existing server using Hyper-V, VMware or KVM, or for smaller installations on a low cost mini PC. Easily move your office phone system to another server or into the cloud using built-in backup and restore.

  • Virtualise with VMware, Hyper-V or KVM
  • Easily scale your installation
  • Run on a low cost MiniPC

Whether in the cloud or on-premise – you are in control. Self host with popular cloud providers such as Google Cloud, Amazon Web Services, OVH or Microsoft Azure. Easily move your hosted PBX between cloud providers with inbuilt backup & restore.

  • AT YOUR DESK   –  Make desk calls from any data connection, with a wide range of feature-rich handsets
  • FROM THE COMPUTER – Use the Softphone App to access directory and make calls, send messages etc
  • ON YOUR MOBILE DEVICE – Take your office number and phone system on the road on iOS or Android
