The PSTN Switch-Off Is Coming – Are You Ready?
The telecoms landscape in the UK is changing fast. Traditional PSTN lines are being retired, and businesses need to move to modern solutions to stay connected and competitive.
In this edition of Unity Comms, we’ll explain the key differences between PTSN and VoIP, highlight the benefits of Mobile VoIP, and guide you on how to prepare your business for the future of communications.
PSTN vs VoIP: Understanding Your Options
Choosing the right telecoms setup is critical for managing costs, supporting growth, and ensuring flexibility.
PSTN (Public Switched Telephone Network)
- Traditional analogue lines using copper wires
- Reliable but limited in features
- Call charges are per minute, which can make costs unpredictable
VoIP (Voice over Internet Protocol)
- Internet-based system that converts voice into digital data packets
- Scalable, flexible, and cloud-ready
- Inclusive call minutes to 01, 02, 03, & 07 numbers, making costs predictable
- Integrates with modern business tools
Why act now?
Openreach is phasing out PSTN completely by 2027, with some areas already switched off. Upgrading to VoIP today helps your business:
- Avoid last-minute disruption
- Gain experience with modern telephony
- Stay ahead of competitors forced to upgrade later

VoIP isn’t just about cost, it’s about giving your team the tools to communicate efficiently, anywhere, anytime.
