“Why Have My Phones Stopped Working?!” Your Quick Guide to the PSTN Switch-Off

You might have heard about the upcoming PSTN switch-off, which is set to happen by January 2027. While your phones are still working today, they might stop working altogether if you don’t act before this deadline. Here’s a quick guide to help you understand what’s happening and what you need to do.

What Is the PSTN Switch Off?

The Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) will be permanently shut down by 2027, making way for IP (Internet Protocol) technology. This transition is happening because the old copper wire infrastructure that supports traditional phone lines can no longer meet modern communication needs​.

Once the PSTN is switched off, every phone line in the UK will operate through fibre networks, making IP-based telephony the new standard. This shift also affects systems like alarms, door entry systems, CCTV, and EPOS machines that depend on old networks​

Why Is This Happening?

The PSTN and ISDN networks are relics of the past, designed in a pre-digital era when mobile phones, high-speed internet, and cloud-based systems were unimaginable. Maintaining these systems is costly and inefficient, especially as businesses increasingly rely on modern digital technologies​. Switching to IP telephony will enable faster, more reliable, and feature-rich communications that fit today’s business needs.

How Does This Affect You?

If your business still relies on traditional phone lines, it’s important to start planning now. After 31st January 2027, if you haven’t transitioned to IP-based systems, your phones, alarms, and other critical systems might stop working​. Even before that deadline, the sale of traditional lines has already stopped, and services are being gradually phased out, so now is the time to act.

What You Should Do Next

Here’s how to ensure your business is ready for the switch:

1. Assess Your Current Setup

Take a close look at what systems in your business rely on PSTN or ISDN. This could include phones, security alarms, payment systems, fax machines, and even door entry systems. Anything running on traditional lines will need upgrading.

2. Switch to Digital Telephony

Move your communication systems to VoIP (Voice over IP) or another IP-based solution. These systems provide greater flexibility, allowing you to take calls on any device, from anywhere, on the same number. They also offer better call quality and cost savings​.

Switching to digital also gives you the chance to modernise your business communications. Whether you need to integrate your phone systems with customer service platforms, enhance collaboration with video conferencing tools, or create a more flexible remote working environment, IP technology can make it happen.
