Future-Proof Your Communications Before the UK's Telephone Network Is Retired
Is Your Business Ready for the PSTN Switch-Off?
The UK's traditional Public Switched Telephone Network (PSTN) is being permanently retired, marking one of the biggest changes to business communications in decades.
Many organisations still rely on analogue phone lines, ISDN services and legacy communications infrastructure that will no longer be supported. While many businesses focus on replacing their phone system, the reality is that a wide range of critical services may also be affected.
Oakford helps businesses identify risks, modernise communications and transition to reliable, secure digital services with minimal disruption.

What Is the PSTN Switch-Off?
For decades, UK businesses have relied on analogue telephone lines and ISDN services for voice communications and connectivity.
These technologies are now being replaced by modern IP-based services that operate over fibre and internet connectivity.
The PSTN switch-off affects organisations of all sizes, from small businesses with a handful of users to large multi-site enterprises operating complex communications environments.
Businesses that fail to prepare could experience service disruptions, increased costs and operational challenges as legacy technologies become unavailable.
More Than Just a Phone System Upgrade
Many organisations are surprised by how many services depend upon traditional telephone lines.
Systems commonly affected include:
- Business telephone systems
- ISDN services
- Analogue telephone lines
- Fax machines
- Lift emergency phones
- Door entry and intercom systems
- Alarm signalling services
- Building management systems
- CCTV connectivity
- Payment terminals
- EPOS systems
- Remote monitoring equipment
- Out-of-hours emergency lines
- Customer service contact centres
Oakford helps organisations identify every affected service before problems arise.
