The Big Switch Off 2025 - What does this mean for your business?
The ‘Big Switch Off’ will result in the phase-out of BT’s ISDN (Integrated Services Digital Network) and PSTN (Public Switch Telephone Network) phone lines. Introducing the VOIP (Voice Over Internet Protocol) technology, allows voice calls to be made over an internet connection. The availability of reliable broadband across the UK means that the change will provide cheaper and clearer phone calls.
Businesses are being urged to have migrated off the aging PSTN/ISDN lines by the end of 2025, to safeguard their services, well before the final shutdown and Switch Off of the network in 2026. When the Big Switch Off happens, any business who have remaining services that have not yet switched to the new digital network will be lost; this includes phone dependent systems such as alarms and door entry systems that run on an analogue line.

The Public Switched Telephone Network (PSTN) is an outdated analogue system that relies on copper wires, making it increasingly fragile and prone to failure. Ofcom reported a 45% rise in major PSTN failures in 2024, highlighting the urgency of switching to a fully digital network. Every phone line in the UK will soon be digital, routing calls over the internet instead of traditional copper lines.
Businesses must act now to review their telecoms infrastructure and ensure a smooth migration. Those who delay could face operational disruptions, increased costs, and lost connectivity. The future of telecoms is digital, and the time to prepare is now.

Yes a VOIP system runs over your existing I.T network and is much more easy to install and configure than a conventional phone system.
The simple answer is the PSTN and ISDN systems are now out of date due to the capability and generally are costly to run and maintain.
It essentially means now is the time to change your current system to a VOIP/ Cloud based phone system. This will provide some big savings on line rentals etc.
