The Public Switch Telephone Network (PSTN) is aging and will reach the end of life in December 2025. The PSTN supports a number of Openreach products which Communication Providers (CPs) purchase at regulated pricing and often sell to businesses and consumers, wrapped up in their own line rental, broadband and call package deal. These include: Wholesale Line Rental (WLR) and Integrated Services Digital Network (ISDN). https://voipexperts.co.uk/remote-working/isdn-switch-off/
