SIP Trunks from Turnkey Telecom Group can replace your traditional analogue PSTN or ISDN lines at a fraction of the cost, with quick and easy installation.  

What are SIP Trunks?  

A SIP Trunk is the virtual link between your PBX and the PSTN over the internet. It allows you to make outbound calls and receive inbound calls using an IP connection (VoIP) rather than a traditional ISDN/PSTN line. With ISDN being phased out and moving to all-IP, SIP Trunks will be essential. 
Our SIP trunks are available from £7.50 per month and include FREE Local and National and UK mobiles calls.
