ISDN and PSTN Switch Off 2025

ISDN and PSTN Switch Off 2025


2025 will bring the end of Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PSTN) services. So this will change to the way UK organisations will need to operate.

What does this actually mean?

Essentially, you need to start thinking of alternatives and changing the way your organisation communicates. There are options already available such as Voice over Internet Protocol (VoIP), which uses data networks to provide you with the same voice service but delivered in a slightly more modern way. It also means you can take advantage of more up to date collaboration tools.

The benefits of switching to VoIP now:

  • Saves up to 50% on line rentals and 25% on calls
  • You’re in control. Add lines, take them away, split calls – it’s up to you
  • Choose how and where you want calls delivered. Make changes instantly
  • Handles emergencies with ease. Business continuity enabled and can reroute calls to backup sites in seconds
