RIP ISDN 1988 to 2025

The end of ISDN has been predicted ever since the rise of Voice over IP (VOIP) but as of last month the CEO of BT Group Gavin Patterson made it clear that 2025 would be end of the road.

Patterson stated:

We already serve many thousands of customers in businesses using IP, our goal is by 2025 all of our voice customers will be served using an IP with a premises solution and will migrate off the traditional telephony platform.”

In a recent blog post Matt Townend, MD of illume, commented:

For BT, this convergence onto the IP network will require them to migrate all of their customers off the ISDN network at some point in the next 10 years. Although this may seem like a long time, the process will take a lot longer than expected and Cavell expects that this will start relatively soon to end of life the service by 2025.”

There has never been a better time to make the change from ISDN to SIP based technologies. The iPBX solution offered by NSN, for example, is a complete ‘off the shelf’ solution that is designed to ensure that life after ISDN can begin as soon as today. It simply enables the customer to continue growing their business without missing a beat.”
