In 2027, the Public Switch Telephone Network (PSTN) will be switched off, disrupting many industries and affecting lives and businesses. Traditional landlines and voice services currently supported by PSTN must be switched to Voice over Internet Protocol (VoIP) before the deadline or systems will stop working. One area that will feel the impact more than most is emergency phones found along motorways. Each emergency phone must be fitted with a two-way communicator, for use in an emergency.  

VoiceLink is the ideal solution for emergency phones, found across motorways, national grid sites, petrol forecourts, airports, 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.   

VoiceLink 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.
