What’s the impact of the UK PSTN switch-off on Zendesk Talk?

Question

What impact does the retirement of the Public Switched Telephone Network (PSTN) have on my Zendesk Talk?

Answer

The United Kingdom (UK) retires its legacy copper telephone network, the PSTN, by January 31, 2027. BT Openreach leads this industry change. The UK government supports this change, and Ofcom supervises it.

Zendesk Talk itself isn't affected. Talk uses Internet Protocol (IP), so calls don't depend on the PSTN. UK phone numbers continue to work after the switch-off.

You can use on-premise telephony, legacy UK landlines, or forward calls through the PSTN alongside Talk. If so, confirm your migration plan with your telecom provider ahead of the 2027 deadline.

For additional information, see the Ofcom guide to move landline phones to digital technology.
