With the 2027 deadline for the Public Switch Telephone Network (PSTN) switch-off fast approaching, many industries in the UK are feeling the pressure to upgrade their communication systems. The PSTN, a staple of traditional landline services, is being phased out in favour of modern digital networks like Voice over Internet Protocol (VoIP). This shift isn’t just about keeping up with the times—it’s about ensuring that vital systems like lift alarms and emergency phone lines don’t go silent. CSL’s solution to this issue is VoiceLink.
From January 31, 2027, the PSTN will be fully decommissioned. That means millions of lines across the UK need to be upgraded, and time is running out. The PSTN’s ageing analogue technology just can’t meet the demands of today’s digital world. That’s where VoiceLink steps in. It converts PSTN calls to 4G Voice over LTE (VoLTE), ensuring that your existing systems don’t miss a beat when the old network goes dark.
Why VoiceLink
VoiceLink is more than just a stopgap; it’s a smart investment for the future. It’s designed to be a cost-effective solution that bridges the gap between outdated PSTN infrastructure and modern VoIP technology. For critical applications like lift alarms and emergency call points, VoiceLink ensures compliance with safety standards and keeps everything running smoothly—no matter what.
Lift Alarms: The UK has around 300,000 lifts, each with a PSTN-dependent alarm system. Without an upgrade, these alarms could become non-compliant, potentially putting lives at risk. VoiceLink makes sure that doesn’t happen.
Emergency Lines: Think about the emergency call points you see on motorways, at train stations, and in other high-risk areas. They all rely on PSTN lines, and they all need an upgrade. VoiceLink keeps these vital communication channels open, protecting public safety and ensuring everything works as it should.
VoiceLink Feartures:
Resilience: VoiceLink comes with a CSL roaming SIM and backup options for 2G and 3G, so you’re covered even in tough conditions.
4G VoLTE: This technology converts PSTN calls to 4G VoLTE, giving you better sound quality and the ability to use voice and data at the same time.
Battery Backup: If the power goes out, VoiceLink has you covered with up to eight hours of standby time.
Easy Installation: VoiceLink is a plug-and-play solution, so there’s no need to reprogram your existing equipment. It’s a quick and painless upgrade.
With the PSTN switch-off on the horizon, finding a reliable and future-proof communication solution is more important than ever. CSL’s VoiceLink offers a simple, cost-effective way to make sure that critical systems like lift alarms and emergency lines stay up and running in a post-PSTN world. It’s not just about staying compliant; it’s about keeping people safe and businesses running smoothly.
