Make the move from ISDN to SIP

Improve flexibility and reliability of your communications infrastructure while reducing cost when moving from ISDN to SIP.

ISDN lines have served businesses well for many years. Their introduction meant better call quality, increased flexibility and higher capacity. As it happens with most technologies, ISDN lines are beginning to seem antiquated. As businesses grow, the demand for lower costs and the requirement for greater flexibility, many companies are finding out that ISDN lines are no longer able to accommodate their requirements.

What is SIP?  

SIP (or Session Initiation Protocol) also known as SIP trunking is a replacement for traditional ISDN. It connects your PBX to the network via a broadband connection. More and more businesses are switching from ISDN to SIP trunking service. There are now more than 1 million SIP trunks in the UK.
