SIP Trunks 

Compared to ISDN our SIP trunking service is less costly per channel and more flexible in how and where geographic telephone numbers can be used.

SIP Trunks connect your customers’ businesses with our nationwide network, gives access to the PSTN and provides a more flexible and lower cost alternative to ISDN for inbound and outbound voice calls.

The benefits of SIP Trunks

Lower cost

First and foremost SIP is significantly less costly than ISDN. It offers your customers the opportunity to make real operational cost savings through free calls to UK 01, 02, 03 numbers, whilst at the same time improving service flexibility.

Line and PBX estate rationalisation

ISDN line rationalisation options and they are the ideal way to reduce the number of PBXs that require maintaining, whilst your customer retains full control of the numbers associated with their business.

Number Flexibility

SIP Trunks support business relocations by enabling a geographic number to be kept without incurring any ongoing call forwarding costs. This not only ensures continuity of business, it also reduces the cost impact associated with having to change company stationery, directory entries and advertisements. We can also supply SIP trunking with out-of-area geographic number ranges for customers who, for example, wish to appear local even if they don’t have a local physical presence.

Business-grade voice and data convergence

With SIP Trunks delivered over Broadband or Ethernet, your customers can have a high-quality voice and data service from just one connection and they’ll make significant cost savings.
