The 2025 PSTN and ISDN Switch Off - It's a big problem


It's a big problem!

Although December 2025 is over 1000 working days away, over 25 million lines will go end of life by the end of 2025. This means that the industry needs to be moving over 24,000 lines per day onto new products and services.

From our experience, we don't think that this is on our customer's radar yet, and that means very few are taking steps to switch and future-proof their business. So while there are some early adopters, the majority haven't really thought about what they are going to do and when.

This means that the number of people per day needing to move is likely to continue growing until it becomes impossible to get everyone moved in time. Yet BT are adamant that the switch off will happen in December 2025 regardless.


And it's worse than that! The WLR Switch Off.

In December 2023, there will be a stop sell on products affected by the WLR switch off, which means that if you want to add or reduce your capacity and use a WLR product, you will not be able to.

And it's even worse than that! The FTTP Rollout.

Running in parallel with the WLR switch off, we also have the rollout of FTTP priority exchanges. If your service is in one of these exchanges, you may already be heading to an earlier stop sell or end of life date. You may then be forced to take FTTP if it's available regardless of if you want to or not.

And it's even worse than that! The switch is complicated.

Depending on where you are and what services and suppliers are available in your area, the options available to you may vary compared to someone just around the corner. This is being compounded by the information from BT Openreach being drip-fed to the industry and the emergence of many new ALTNET suppliers who are springing up on the back of the perceived opportunity around full-fibre. Not only that, but because of the difference between the way Voice is provided in the new world, you may need to have extra wiring done or upgrade a range of devices that you depend on to run your business.
