PSTN Switch Off Explained: All You Need to Know About

As technology continues to advance at a rapid pace, traditional telecommunication networks are undergoing a significant transformation. One notable development is the Public Switched Telephone Network (PSTN) switch off, which includes the Integrated Services Digital Network (ISDN) switch off, particularly in the UK with the impending BT 2025 switch off.

The PSTN switch off refers to the phasing out of the traditional landline-based telephone networks, making way for more modern and efficient communication technologies.
