Since BT announced that they were switching off the UK’s ISDN telephone network, the 2025 deadline is now firmly in sight and the countdown has begun.

What does this mean for your business?

By deciding to phase out the ISDN system, BT have acknowledged that communication has changed and that Internet over Protocol (IP) systems – such as SIP Trunks – is the next big step for businesses. Therefore, BT decided not to invest any more time or money in a system that won’t enhance a business’ ability to communicate.

In addition, the maintenance and running costs of ISDN systems are also the most expensive which means the longer you hold on to your ISDN systems, the more it’ll cost your business. By migrating your ISDN lines to SIP Trunks, you’ll only have to maintain one.

What are SIP Trunks?

Session Initiation Protocol (SIP) trunks is a voice over internet technology which can deliver telephone and video services on a global scale, using computers and mobile devices with a secure internet connection.

The biggest comparison between ISDN and SIP trunks for businesses is cost, as communications between SIP users is free. A study by TalkTalk found that 96% of businesses which had already made the switch were making cost savings. *

It’s Time to Take Action

In early 2017, there were over 2 million businesses still with an ISDN connection in the UK. **

So, whilst the deadline seems quite far away, in fact the move towards cloud-based telephony is happening right now. The more time you can commit to a project, the better it’ll be so it’s important to start thinking about making the move sooner rather than later.
