The PSDN and ISDN Switch-Off is coming.
Is Your Business Ready?
By 2027, traditional phone lines will be retired across the UK. Discover how to easily go digital and keep your communications strong for years to come.
Understanding the Change
The UK is retiring the Public Switched Telephone Network
(PSTN) and Integrated Services Digital Network (ISDN) by the
end of 2027. These legacy systems are being replaced by
faster, more reliable digital networks. Openreach will switch
off copper analogue lines. This means if your business relies
on copper landlines for calls, alarms, fax machines, or card
readers, it’s time to plan your migration to digital.

Switching from Analogue to Digital Landlines
Migrating to a digital phone system like VoIP or hosted telephony
Moving to a hosted solution is cost effective because the installation and maintenance costs are minimal. A hosted solution also means that you avoid paying expensive traditional phone line bills, as your calls will be placed over competitively priced internet connectivity instead.
