The Great BT ISDN Switch Off

BT intends to go forward with the ISDN Switch Off 2025, which means networks for good, starting with a cease in supply in 2020 and moving to a full migration by 2025.

THE GREAT BT ISDN SWITCH OFF: BT PHASING OUT ISDN BY 2025

The ISDN Switch Off 2025 could affect many businesses in the near future, especially those unaware of BT phasing out ISDN and looking to invest in or upgrade their current business telephone system. BT intends to switch off the ISDN and PSTN networks for good, starting with a cease in supply in 2020 and moving to a full migration by 2025.

Why Are BT Phasing Out ISDN and PSTN?

The short answer is that they are old fashioned legacy technologies with associated maintenance costs and drawbacks. PSTN is the traditional telephone line network which carries analogue voice data over copper lines. This technology (although vastly improved upon over the years) is basically the same in principle and design as the early telephone networks of the late 1800’s.

The BT ISDN switch off marks the next evolution of telecommunications technology

ISDN was introduced in the 1980’s, allowing both voice and data services to be delivered simultaneously. For the technology and services at the time, it served its purpose very well and continued to do so for many years. Now we’re well into the 21st century, technology has moved on and old telephone solutions are lagging behind the alternatives in an increasingly fast paced digital world.

How To Prepare For The BT ISDN Switch Off 2025

Although the BT ISDN end of life of 2025 has not been set in stone, businesses will be unable to buy systems that use ISDN and PSTN after 2020. If you currently have a traditional ISDN/PSTN based system, now is a good point to look into the alternative. Although there is plenty of time until 2025 rolls around, it’s best to plan ahead and you may actually find you want to migrate sooner rather than later after finding out all of the benefits the replacement ‘IP’ based systems have to offer.

It’s very affordable/cost effective

There’s no need for masses of on site equipment, you only pay for as many users as you need and calls are made through internet lines.

Easy setup & maintenance

Because there is so little on site equipment, setting up and maintaining the system is a much simpler job than with a traditional telephone system.

Freedom

The flexible nature of the technology allows you to easily add and remove users as you need. Physical location doesn’t matter, anywhere you’ve got an internet connection, you can have a number.
