By 31st January 2027, the Public Switch Telephone Network (PSTN) will be switched off, disrupting many industries. Traditional landlines and voice services currently supported by PSTN will need to be switched to Voice over Internet Protocol (VoIP), before the deadline.
VoiceLink is the ideal solution for lift alarms, found across retail, local councils, hospitals and business premises. It can also upgrade emergency phone lines that are present in many high-risk environments such as motorways, national grid sites, and petrol forecourts.
There are 14 million lines and channels across the UK, with 7 yet to be upgraded.
Enquire NowVoiceLink converts PSTN calls to 4G VoLTE, ensuring analogue systems are future-proofed and can continue to make voice calls. The solution creates a bridge between the old and new technology, and allows existing devices to continue working after the PSTN Switch-Off.
Our solution will ensure that end user systems remain uninterrupted, ensuring business continuity and/or public safety is not compromised. VoiceLink is a lower upfront investment compared to alternative solutions and creates a recurring revenue stream, growing the value of any business.
With VoLTE, users can call and have fast data transfer at the same time, which leads to cost savings and increased efficiency. Moreover, sound quality is often an issue in many high-risk sites, as well as lifts. VoLTE enables high-definition voice quality which is essential to providing reassurance for whoever is making the emergency call.
There are 300,000 lifts in the UK. Every lift has an alarm, usually a button that connects to a rescue service via a preprogrammed phone number. If not upgraded, these PSTN-dependent systems will fail to meet operating standards, putting lives at risk.
Current UK law requires a lift service or maintenance visit at least every 6 months. VoiceLink is quick and simple to install on a routine visit, cutting down installation and labour costs.
Emergency call points, such as the types found on the side of motorways, train stations, petrol forecourts, national grid sites, and reservoirs rely on a physical phone line. They must be upgraded before the PSTN connection is switched off.
There are call points at approximately every 1 mile interval on UK motorways.
The energy sector uses 43,000 lines to monitor services, while the water sector relies on 25,000 lines to function.
