Providing Outstanding Communication Solutions For Business

SIP Trunking

8th March 2019

ISDN phone lines are being completely phased out within the next few years. There has never been a better time to consider switching your communications system to more sophisticated and agile technology.

SIP Trunking Solutions explained

Session Initiation Protocol (SIP) Trunking is a way of delivering voice services over the Internet. SIP can be supported on the IP (Internet Protocol) based phone systems or we can use a Gateway to connect to legacy ISDN2e or ISDN30 telephone lines

SIP trunks are the modern alternative to ISDN.

How we can help

There are still around two million ISDN trunks in everyday use across the UK. If you’re still using them in your business it’s probably because;

  • Your existing PBX can’t support SIP Trunks
  • It’s too costly to add to your existing PBX
  • Your existing PBX does everything you need and you want to maximise your investment for as long as possible

ISIP is a range of ISDN to SIP converters which allows you to keep your current PBX, whilst providing instant access to all the benefits of SIP.

ISIP is simple to deploy – just un-plug the ISDN cables from the BT service, plug them into ISIP, connect your new SIP service and away you go. ISIP is cost-effective and available in seven different Basic Rate/ISDN 2 & Primary Rate/ ISDN 30 variants – just choose the one that matches your current ISDN trunk capacity.
