Intercity_ISDN_guide copyWhy ISDN will be switched off in 2025

ISDN, otherwise known as the Integrated Services Digital Network, is the infrastructure currently utilised by the UK for voice communications. 
It is a circuit switched network which transmits voice and data via the traditional circuits from PSTN, otherwise known as the Public Switched Telephone Network.
Openreach have shared plans for all ISDN products to become obsolete by 2025, and there are many reasons why your business should be switching as soon as possible:
  • Save money - On average, save up to 50% on your line rental & 25% on calls.
  • Enjoy higher quality transmission and speeds - by moving from traditional copper services like ASDL and FTTC to the latest full fibre technologies you remove the need to use the PSTN, giving you a better quality network to run your IP telephony soloution.
  • IP telephony solutions give you greater flexibility and management control over your concurrent calls, geographical presence and DDIs as well as your call routing options.
  • IP telephony solutions handle emergencies with ease - with predefined Disaster Recovery (DR) call routing built in you can reroute calls to backup sites in seconds.
