The ISDN switch off is due to take place in 2025, and BT will stop accepting amendments and new orders in 2020.

Does this fact fill you with dread? Not sure what the alternative is?

Don’t panic, it will all be okay. We’ve taken the ISDN geeky stuff and simplified it below –

What is ISDN?

ISDN is a type of telephone connection that businesses use. It stands for Integrated Services Digital Network.

They’re the step up from your normal home landline connection in that they offer multiple calls to one number, video conferencing and other business requirements.

It was first offered out to businesses in 1980 and offered the best technology for phone systems at the time.

Why the ISDN Switch Off?

So, after reading the above you may be thinking why would BT switch off such a great product? Well, the answer is that ISDN has had it’s hayday, but there is now a much simpler, and cheaper alternative.

That alternative is VoIP or Hosted PBX, phone lines over the internet rather than the copper cables that ISDN connections use.

Just like the technology in our mobile phones is improved and enhanced regularly, so business phone system technology changes. You could look at Hosted PBX as the newer model of ISDN with one big difference.

Internet phone systems are actually cheaper than ISDN, and that’s one of the main reasons for the ISDN switch off. BT have realised that within the next few years more and more businesses of all sizes are going to swap over to internet systems.

What can you do to prepare?

The first thing you can do to get prepared is to find out when your current ISDN contract expires. 2025 may seem like a long way off but it will come sooner than you think.

Rather than signing up for another year with your traditional phone system, why not start looking into internet phone systems now and get ahead of the curve? Go to a few VoIP providers and get some quotes.
