Frequently asked questions

There’s a lot happening over the next few years, so you probably have some questions.

  • The existing PSTN service is ageing, and it’s no longer sustainable to support today’s communication requirements. It’ll reach the end of its life by 2027, which means the analogue telephone voice service that’s reliant on the network won’t be available anymore. 

  • ‘Stop sell’ means no new WLR services will be offered in the impacted areas. Stop sell also restricts existing WLR services.

  • As PSTN closes, there are a number of other products which can underpin migration, covering both broadband and Ethernet. For voice services, you’ll need an IP voice product over the top of the underlying access. We’ve put together some FAQs within our interactive guide which should answer any questions you may have. If you want to know more, just get in touch with us.

  • We all know the public switched telephone network is being shut down in 2027. But what’s the best way to prepare your customers and your business for the change?
