We’re all familiar with the copper wire telephone network: in use since 1876, it’s kept business communications’ going for years. But that’s all about to change.

In 2025, the Public Switched Telephone Network (PSTN) is being switched off by BT Openreach, which means everyone, including businesses, currently using PSTN-based services will need to move to another service before then.

The alternative? Voice over Internet Protocol (VoIP), a solution that transmits voice calls and data using an internet connection.

This is a major step towards the United Kingdom’s mass IP-network migration, with VoIP core networks set to replace all the legacy PSTN services in just a few years’ time.

Embrace the future of telephony by replacing your landline with VoIP before the Public Switch Telephone Network (PSTN) is switched off in 2025.
