The final countdown to the PSTN Switch-Off in the UK is on!

As of September 5, 2023, BT Openreach initiated a nationwide stop-sell of single and multi-line PSTN and ISDN lines, marking a significant milestone in the transition to newer technologies and signaling the beginning of the phase-out process. The full PSTN switch-off is scheduled for 2025.

For over a century, the traditional Public Switched Telephone Network (PSTN) has been the backbone of phone calls in the UK. This event signifies a monumental shift into a new era in telecoms, with digital services—particularly Internet Protocol (IP) or Voice over Internet Protocol (VoIP) systems—now taking centre stage.

The term "stop-sell" means that you are not able to purchase any new services or modify any existing services that rely on ISDN or PSTN, but can continue using pre-existing legacy PSTN services until the complete switch-off in 2025.

Why is this happening?

To put it simply, the PSTN, a complex infrastructure of telephone lines, satellite links, and switching centers, has been outpaced by the capabilities of internet calls, video conferencing, and collaborative online tools. All organisations across the UK now need to migrate to alternative solutions, with many already having made the switch to VoIP technology, allowing their users to make phone calls and transmit data over an internet connection.

Why Act Now?

With the PSTN switch-off deadline looming, the urgency to adopt IP telephony is clear. Businesses need to act to ensure a seamless transition and avoid disruptions. The year 2025 may still seem distant, but in reality, it's less than two years away. Businesses that delay the adoption of IP telephony may face challenges beyond just losing the ability to make calls. Alarm systems and emergency points of contact often tied to PSTN will also become inoperable without the necessary upgrades.

Your Path to a Digital Future: Why VoIP?

Transitioning to VoIP future-proofs businesses, providing advanced features, scalability, and significant cost savings. VoIP enhances flexibility and mobility, allowing employees to communicate from anywhere with an internet connection. It is a key enabler of modern work models, supporting remote and hybrid work and improves collaboration. Moreover, VoIP ensures reliability, redundancy, and aligns with the trend of unified communication, integrating various channels into a cohesive platform.
