Are you ready for the big UK ISDN switch-off in 2025?

In 2025, all of the UK’s PSTN and ISDN networks will be switched off. These are phone lines that we have been using for decades to make calls, so what can you do to reduce disruption to your business? Join us as we tell you all about the UK ISDN switch-off and the next steps you need to take.

What is the UK ISDN switch-off?

Announced by BT in 2015, the big switch off means all ISDN and PSTN services will be turned off. In some regions the UK ISDN switch-off has already happened, and as of 5th September this year, customers can’t order, move or amend conventional analogue lines, which is why it’s worth switching over to digital communication systems sooner rather than later.

Does this affect me? 

From our own research, we’ve found that around 75% of businesses that need to switchover have already done so, typically to VoIP services. If your business phones or services operate using the old analogue network, you will have to switchover to digital lines. As the UK ISDN switch-off deadline comes closer, it’s time to take action in order to avoid being cut off, losing numbers and affecting everyday business communications.

What are the benefits of switching to digital telecoms solutions?

So, with all this talk about the UK ISDN switch-off, what good stuff can come from changing to hosted or cloud services? 

  • Consistent monthly costs
  • Ideal for hybrid working; from home, in the office or on the move (phone, laptop, mobile) 
  • Easily manageable system  
  • Improves customer service experience 
  • Option to scale up to suit your business’ needs
