What is SIP Trunking?

Perfect for businesses wanting business continuity, multi-site line rationalisation or are moving office

About SIP Trunking

SIP Trunking (Session Initiation Protocol Trunking) is a Voice over Internet Protocol and streaming media service, based on the Session Initiation Protocol. Compared to ISDN SIP trunking is cheaper per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and it delivers extremely robust business continuity.

The service can support connections ranging from two channels for small PBX-equipped businesses to an unlimited number of channels for large businesses and contact centres.

SIP Trunking is perfect for any businesses facing these challenges:

Business Continuity – should you be unlucky enough to suffer from a flood or fire having SIP Trunking will minimise the disruption by diverting calls to a different office.

Multi-Site Line Rationalisation – if you have multiple sites with ISDN connections you can reduce the number of ISDN connections you need by using SIP Trunking and this will also reduce your maintenance costs too! Your remote sites just have the cost of an IP connection and handsets.

Adjustable – You can add more lines quickly as and when you need them – ideal for when your busy and the volume of calls increases without any long term contracts or commitments.

Moving Office – if your moving office YOU CAN KEEP YOUR EXISTING NUMBER with SIP Trunking! No diversion of Remote Call Forwarding charges!

Flexible number display – You choose which number you want to display on each call, this is great for contact centres.

Who can have SIP Trunking?

Any business with a PBX can switch to a SIP Trunking service and immediately benefit from a more flexible, less expensive and more resilient phone service.
