The PSTN Switch-Off is Happening: Is Your Phone System Ready for the Digital Shift?
If your business or school relies on a traditional landline plugged into a wall socket, the clock is ticking. Openreach is currently in the process of retiring the Public Switched Telephone Network (PSTN)—the copper wire network that has powered UK communications for over a century.
By January 2027, the old analogue network will be switched off entirely. Every phone line in the UK will need to be digital, routing calls over the internet (VoIP).
It’s More Than Just Phones
Most organizations understand they need to upgrade their telephone handsets. However, the “PSTN Switch-Off” affects far more than just voice calls. Many critical pieces of legacy infrastructure rely on these analogue lines to send data, including:
- Red Care / Intruder Alarms
- Lift Emergency Phones
- Fax Machines
- PDQ / Card Payment Terminals
- Door Entry Systems
If you simply wait until the switch-off date, these devices will stop working, potentially leaving your building non-compliant with safety regulations or unable to process payments.
The VoIP Opportunity
While this switch-off is forced, it is also a massive opportunity. Moving to a Voice over IP (VoIP) system offers benefits that analogue lines never could.
- Flexibility: Your phone number is no longer tied to a physical building. You can answer your office line from an app on your mobile, from home, or from a temporary office.
- Cost Savings: VoIP calls are significantly cheaper than traditional landline calls, and line rental costs are often lower.
- Integration: Modern VoIP systems integrate with your IT, allowing for voicemail-to-email, click-to-dial from your PC, and better call reporting.
What You Need to Do Now
Don’t wait for the deadline. Start an audit of your infrastructure today. Identify every analogue line in your building and plan your migration to digital alternatives.
