VoiceLink<\/span><\/h1>\r\n
\r\n

With the Public Switch Telephone Network (PSTN) switch-off set for January 31, 2027, essential services must prepare to transition to Voice over Internet Protocol (VoIP). CSL\u2019s VoiceLink ensures legacy analogue systems, such as traditional landlines and voice services, remain operational, providing a secure, future-proof solution for continuous connectivity.<\/p>\n <\/div>\r\n

What is<\/span> VoiceLink? <\/h2>\r\n
\r\n
\r\n

VoiceLink converts analogue PSTN data and calls to 4G VoLTE, allowing your legacy systems to stay connected as the PSTN network phases out, reducing costly equipment replacement needs. With a built-in battery backup, VoiceLink remains operational for hours during power outages, ensuring uninterrupted service for critical systems like lift alarms and emergency lines. Additionally, VoLTE\u2019s high-definition voice quality provides essential reassurance for emergency callers.<\/p>\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

Lift Alarms<\/h2>\r\n

With approximately 300,000 lifts in the UK relying on emergency alarm systems that connect via PSTN, the upcoming switch-off threatens to leave these systems non-compliant and potentially unsafe. VoiceLink provides a straightforward upgrade solution that is easy to install on a routine visit, cutting down on installation and labor costs while ensuring lift alarms remain connected, reliable and fully aligned with safety standards.<\/p>\n<\/div>\r\n <\/div>\r\n <\/div>\r\n

Emergency Lines<\/h2>\r\n

Emergency lines at motorway SOS points, petrol forecourts and national grid sites are crucial for public safety and require uninterrupted connectivity. VoiceLink keeps these lines operational through the PSTN transition, providing seamless, secure connectivity that meets stringent safety and compliance standards.<\/p>\n<\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n<\/section>\n\n\n\r\n
