ISDN2 lines will be turned off by BT in 2024 to co-inside with improved fibre connection across the UK. So it is the time to upgrade your existing PBX to SIP Trunks.
SIP Trunks are a form of telephone line that connects your business to the Public Telephone Network (PSTN) using a data circuit and Voice over IP (VoIP), rather than traditional BT analogue or ISDN lines.
Compared to ISDN, SIP Trunks are less costly per channel and more flexible in how and where geographic telephone numbers can be used. They’re also quicker to install and provision and, as standard, they deliver robust business continuity.
The service can support connections ranging from two channels for small businesses to an unlimited number of channels for large enterprises and contact centres.
Business SIP Trunking is now the standard for any business needing voice calls. With one-off and monthly rental costs being up to 70% lower than ISDN, businesses can stop spending high amounts on telephone lines. Call charges are also currently increasing on ISDN but decreasing with SIP meaning even more money can be saved.
So, whether you are moving office, looking to reduce costs or consolidate lines at multiple locations SIP trunking is the solution of choice.
