The Big Landline Switch Off, Is Your Business Ready?

You may have heard of the ISDN & PSTN switch off, but do you know how it’ll impact your business and are you aware of the alternative solutions?

The telecommunication landscape is on the brink of a significant transformation with the impending 2025 (now updated to Jan 2027) Public Switched Telephone Network (PSTN) switch-off. As businesses brace themselves for this digital shift, it becomes crucial to understand the implications and prepare proactively.

What’s happening?
Back in 2015, BT announced that they will be switching off the Public Switch Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) in 2025 (now updated to Jan 2027).

Why is it changing?
Simply put, to keep up with advancing technology.
Over the years we’ve seen so many changes in technology, with increased usage in smartphones, apps, IoT and more.

Did you know that some of the UK’s copper telephone network is over 140-years old!?
So, it’s definitely time for some modernisation.

Time is ticking with the switch off happening in 2025 (now updated to Jan 2027), so now is the perfect time to get familiar with what’s happening and plan your next move.
We’re now able to move to a fully digital network, instead of using the old copper lines that was traditionally used.

How does this impact my business?
The change is happening for everyone – both businesses and home connections. This means you’ll need to upgrade your telephony sooner rather than later, because you don’t want to get left behind!
