The UK phone network is changing.
PSTN, ISDN and ADSL services are being switched off by 31 January 2027.
That could affect business phone lines, alarms, EPOS, CCTV, door entry systems, lifts, fax machines and older broadband services.
At Hillsnet , we help businesses move to modern VoIP and IP-based connectivity, with options for 4G/5G backup to keep critical services online.
