The PSTN switch-off isn’t just about your phone system
2nd September 2026

As the UK moves away from the traditional analogue telephone network, businesses need to look beyond their desk phones.
The PSTN network has historically supported far more than voice calls, including:
📞 Business phone systems
🚨 Fire & security alarms
📹 CCTV systems
🛗 Lift emergency phones
🌐 Broadband connections
🚧 Automated gates & barriers
🥤 Vending machines
💳 Card payment terminals
…and many other critical devices.
The risk?
You could successfully migrate your business phones to VoIP, Teams or another modern solution and still have critical equipment relying on the old network.
That’s where Digital Origin’s PSTN Switch-Over Service comes in.
We help businesses identify, assess and migrate every service that could be impacted, giving you confidence that nothing gets left behind.
Our team can:
✅ Audit your existing PSTN-dependent services
✅ Identify hidden risks across your sites
✅ Recommend the right replacement connectivity or technology
✅ Manage the migration and switch-over
✅ Coordinate with third-party equipment providers where required
✅ Minimise disruption to your business
Don’t wait until an alarm stops working, a lift emergency phone goes offline or a payment terminal fails.
The PSTN switch-off is a technology change, but the impact is very much a business continuity issue.
Let Digital Origin take care of the switch-over, so you can get on with running your business.

Frequently Asked Questions
We can assess your current services, identify any risks, and recommend the most appropriate digital solution to ensure a smooth transition before the PSTN switch off.
A review of your current phone system, broadband services, and connected devices will identify whether any services rely on the PSTN network. Digital Origin can help with this.
If your phone system relies on traditional phone lines, ISDN, WLR, or analogue technology, it is likely to be affected by the PSTN switch-off and may need upgrading or replacing.
The PSTN switch-off means traditional analogue phone lines will be replaced with digital, internet-based services. If your business relies on landlines, broadband connections, alarm systems, payment terminals, CCTV, lift emergency phones, or other equipment connected to the PSTN network, these services may need upgrading or replacing. Planning ahead will help ensure a smooth transition, minimise disruption, and allow your business to take advantage of more flexible and feature-rich communication solutions.
The Public Switched Telephone Network, PSTN switch-off, will happen on 31st January 2027.
