The PSTN & ISDN Switch-Off: Is Your Business Ready?
All Copper Phone Lines Will Be Switched Off by 2027
The UK’s traditional phone network the Public Switched Telephone Network (PSTN) is being permanently switched off in 2027.
This means all analogue phone lines (PSTN and ISDN) will stop working, including most traditional business phone systems, alarm lines, fax machines, and older broadband connections.
After 2027, only digital, internet-based phone systems (VoIP) will continue to operate.
Businesses that don’t migrate before the deadline risk being completely disconnected from their customers.
Services Affected by the Switch-Off:
-
PSTN and ISDN phone lines
-
Fax machines
-
Alarm monitoring lines
-
Door entry and intercom systems
-
Broadband connections running on copper lines
