ISDN Switch Off

What is ISDN and when is it being switched off?

ISDN is a traditional phone line technology which often uses a network to deliver voice and data. A number of countries have already made the switch and many are getting close. In the UK – BT are expected to reach the end of sale of ISDN services in 2020 with ISDN services expected to be switched off on the BT network in 2025.

All businesses will then be required to utilise SIP or hosted technology.

SIP Migration Steps

With the ISDN Switch Off, migrating to SIP technology should be a business priority. A SIP Trunk is the digital equivalent of a traditional phone line, it connects to a PBX, a device that provides the brains behind the phone system enabling multiple users to share lines. SIP offers a number of key advantages over ISDN including carrying voice and data across a single connection.

As a company, we recommend moving to an NEC telephone system. NEC has technology ready for this migration, including the SL2100 and SV9100 Communication Platforms.
