The UK is entering the final stretch of its analogue phone era.
By the end of January 2027, the country plans to retire the PSTN. This marks the end of a network used for decades. Businesses and households must move to digital landlines, VoIP, mobile, or cloud-based services.
For many organisations, the change should unlock better communications. Digital services support remote work, call forwarding, voicemail, collaboration tools, and software integrations. They also scale more easily than traditional landlines.
However, the migration brings real operational risk. Some firms still use old phone systems. Alarms, lift phones, payment terminals, and telecare devices may also rely on analogue lines. Many users may not know they are affected.
Crystaline Director and Co-Founder Kristian Torode says the UK has made “strong progress” toward the switch-off. Yet he adds that “readiness is becoming a capacity question as much as a technology one”.
Migration can take 30 to 60 days, according to Torode. Engineer availability could become tight near the deadline. That may create avoidable service disruption for late movers.
“For a business without a telecoms team, the provider should effectively become an extension of that team,” he says.
The most difficult cases may appear near the end. These will include smaller firms and vulnerable users. Some may lack internal technical support. Others may not understand which services depend on legacy lines.
Torode warns that delays could reduce flexibility. “The risk is not that migration becomes impossible, but that a seamless handover becomes harder to guarantee, increasing the chance of broadband or phone downtime and disruption to business continuity.”
Meanwhile, Vonage Chief Innovation Officer Jens Jenson sees a wider opportunity. Vonage is part of Ericsson. He believes the UK can build stronger communications after the shutdown.
“The UK’s move away from the PSTN is necessary, and the transition brings with it a genuine opportunity to build something better,” he says.
He also points to mobile networks as a strong alternative. Norway and Sweden have already shown mobile-first migration paths can work. This matters where fixed broadband remains limited or unreliable.
Still, Jenson says awareness alone will not be enough. Providers must explain the impact in plain language. They must also help customers test replacement services before cutover.
CallTower Telecom Product Owner Ryan Osbourne takes a similar view. He says modern cloud infrastructure already gives the UK the tools it needs.
“The UK should be ready for the PSTN switch-off, provided that businesses and consumers take advantage of the modern cloud infrastructure already available,” he says.
The deadline now places responsibility on both sides. Providers must identify affected services and offer practical migration help. Businesses must stop waiting and audit every line, device, and location.
The UK appears technically ready for the switch-off. The harder task is reaching everyone in time. For the final users, clear guidance may matter more than the technology itself.
