The UK PSTN switch-off deadline is approaching, pushing businesses to migrate from analogue phone lines to VoIP, digital landlines, and cloud communications. With engineer capacity tightening and legacy devices at risk, early audits and provider support are essential to avoid downtime, improve resilience, and unlock smarter business communication tools today.
Openreach’s 2027 PSTN switch-off is accelerating the UK move to fibre broadband and VoIP phone systems. With hidden legacy lines still powering alarms, payment terminals, fax machines, and telecare, businesses must audit connections now to avoid disruption, rising costs, and rushed digital voice migration as copper services reach end-of-life deadline.
Openreach is urging UK businesses to act before the PSTN switch-off, with copper phone lines closing on 31 January 2027. Firms still using legacy systems risk disruption to calls, alarms, payments, and security. Migrating to VoIP and digital phone services now ensures continuity, flexibility, and future-ready communications across every site.
