The PSTN (Public Switched Telephone Network) deadline 2025-2

No, the sale of traditional phone line services, including copper-based and Fibre to the Cabinet (FTTC) connections, has ended as of September 2023. These older networks are incompatible with the transition to digital. While you can no longer purchase or modify these services, maintenance support will continue until the final switch-off. 

Absolutely. PSTN was designed for the 20th century and struggles to meet modern communication demands. As reliance on mobile and internet-based technologies grows, transitioning to IP offers significant advantages:

• Flexibility: Make and receive calls on any device using the same number.

• Integration: Link calls, video chats, and collaboration tools with business applications.

• Cloud Access: Store and access systems from anywhere, enabling remote work.

Cloud telephony is an internet-based phone service that reduces costs by eliminating the need for on-premises equipment. It uses VoIP (Voice over Internet Protocol) technology to provide advanced features and flexibility via the cloud.

IP telephony includes cloud telephony but also covers SIP (Session Initiation Protocol), which connects legacy on-premises equipment to modern digital networks.

 The digital switch-off will impact everyone—businesses and households alike. This includes not only phone services but also non-voice systems that rely on PSTN or ISDN lines, such as alarms, EPOS machines, door entry systems, CCTV, and fax machines.

The PSTN network has supported the UK’s communications for decades, but advances in technology have rendered it outdated. Modern innovations like smartphones, cloud services, and the Internet of Things demand infrastructure that PSTN cannot support. The copper wiring that underpins the network, some of which dates back to the 19th century, is no longer adequate. 

Switching to digital requires careful planning, especially since it affects more than just phone calls. Devices connected to your phone line, such as alarms and door entry systems, may need to be upgraded or replaced. Many businesses have already embraced digital communications by adopting cloud-based solutions, internet calling, and video conferencing. Starting now ensures a smooth transition ahead of the 2027 deadline.
