The system consists of the core phone system which can either be a branded server or built to specificaiton depending on your requirements. The phone system software is then installed along with our proprietary managment and configuration interface.

This is then connected to your network** along with the desk phones. There are a wide range of phones available ranging from simple single line phones up to full featured phones capable of handling many simultaneous calls and multiple extension boards. We can also provide a range of DECT phones.

*The number of lines available depends on the type of phone lines used or the SIP provider limits.
The expected number of extensions should be discussed prior to installation so we can provide an appropriate system as larger offices may require more powerful hardware.

**We highly recommend installing a seperate network switch for your voice traffic for optimal performance.
