So, what do all these confusing terms mean?


  • ON-PREMISE on-premise telecommunications is a system that is physically on your business premises and this is often referred to as a PBX (Private Branch Exchange). It can be VoIP (Voice over Internet Protocol) or digital systems. You will receive the dial tone directly into your premises via your phone system.
  • HOSTED – Unlike on-premise solutions, hosted allows your phone solutions to be hosted in the cloud, therefore there is no need for you to have any hardware in your building and no need for any ISDN lines which is great for the future. Lines that are dedicated to your business only, can be leased and it allows your communications to be flexible, reliable and efficient.
