With a VOIP Cloud Phone System

BT has previously announced that they will be switching off their existing PSTN and ISDN lines and new modern technology will be replacing it. Before now we didn’t know exactly when this was going to be happening which has been quite stressful for company owners who are near the start of a long lease. Should you switch now and pay the buyout penalty and be ready or hold on until your system suddenly stops working. The good news is that BT have announced the switch over will be in 2025, giving the millions of companies still using PSTN and ISDN lines time to consider their options when switching.

what is isdn?

Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network. Put simply your standard telephone line is used to send voice and data over the same line. This is why you can make phone calls on a home telephone and plug your broadband router in to access the internet using the same port.

why is bt switching to ip?

BT introduced ISDN nationwide in 1986 and since then connectivity has advanced greatly. The recent investment and nationwide roll out of superfast fibre internet and new Ethernet products provides a viable alternative. In fact BT have not installed any new ISDN lines in central London since 2014 which goes to show that many businesses have already moved on. But switching over 3 million active ISDN users is no small task which is why they have given businesses so much notice.
