Are you ready for the PSTN Switch-Off?


K


ey elements of your security and safety systems could be facing imminent obsolescence, including lift alarms, emergency call points and monitoring services. In 2027, the Public Switch Telephone Network (PSTN) will be closed down, requiring all voice services to transition to Voice over Internet Protocol (VoIP). The task of future- proofing these services doesn't have to be complex and or entail significant expenditure – if you choose the right partner.


VoiceLink – ensures a seamless PSTN switch-off transition


Leading critical connectivity provider CSL has developed a cost-effective solution to this problem with VoiceLink.


This converts PSTN calls to 4G VoLTE, ensuring analogue systems can continue to make voice calls. This solution creates a bridge between old and new technology and allows existing devices to continue working after the PSTN switch-off.
