FLEXIBLE
SIP TRUNKS
SIP Trunks offer a more flexible and lower cost alternative to ISDN for inbound and outbound voice calls.
Future proof your communications with SIP Trunks
SIP trunking is the IP based replacement for traditional ISDN circuits which BT has announced are being withdrawn by 2025. It connects your PBX or telephone system to the PSTN via broadband, ethernet or private circuit into the national network.
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. It’s also quicker to install and provision and, as standard, it delivers extremely robust business continuity.
Flexibility & Resilience with SIP Trunks
SIP trunking is the latest form of technology that delivers telephone lines using an external data connection as the bearer for the purpose of making and receiving calls. This virtual IP based service uses network data connectivity instead of dedicated fixed line technology methods.
Similar to ISDN, SIP trunks offer multiple flexible lines, unlimited direct dial ranges and caller display. However, SIP trunking provides the ability to converge your voice calls and data onto a single data connection enabling cloud and site based resilience.
