A guide to the PSTN switch off

A guide to the PSTN switch off

We’ve put together a quick guide to help you understand what the switch off means for your business, and the options for your next steps.

What's inside?

In 2019, it was announced that the Integrated Service Digital Network (ISDN) and Public Switched Telephone Network (PSTN) would be switched off in December 2025. This has now been delayed till January 2027.

With less than 3 years until that date, businesses need to be forward-thinking and start to make their contingency plans, because customers are no longer able to purchase new lines, with the complete switch off taking place in 2025.

Our quick guide will help you understand what the switch-off means for your business and the options for your next steps.

  • A brief introduction to the PSTN and ISDN networks, and what the 2027 switch off means for your business.
  • An introduction to VOIP (Voice over Internet Protocol) systems - the replacement service for the legacy networks.
  • What do next, and where to get started with updating your phone systems.
