SIP Trunk Services


A cost effective alternative to ISDN and Multi-Line PSTN lines used for inbound and outbound voice calls on traditional and PBX systems.

SIP trunks are the replacement for ISDN and PSTN service that are being phased out from 2020 onwards. In 2025 the plan is to trasnisiton all traditional PBX lines from ISDN and PSTN to SIP trunks or to HOsted SIP trunks or other Cloud Telephony services such as our Express Cloud Tephony PBX system, our flagship product.

 

SIP Trunks connect up using Broadband, ethernet or private circuits such as Fibre Optic Leased Lines.

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.

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