The PSTN/ ISDN Cut-Off September 2023: What You Need To Know  

In a rapidly evolving digital landscape, it is essential for businesses to stay up to date with the latest advancements in technology. One significant change on the horizon is the impending ISDN and PSTN (Integrated Services Digital Network and Public Switched Telephone Network) cut-off, with BT no longer selling these lines as of September 2023.

The PSTN and ISDN Sunset

PSTN and ISDN were once ground breaking technologies and have been reliable communication solutions for businesses worldwide for decades. They have offered a range of services, including voice calls, data transfer, and video conferencing. However, as the telecommunications industry embraces more advanced and efficient alternatives, the time has come to bid farewell to ISDN and PSTN.

Why the Change?

The decision to discontinue ISDN and PSTN is driven by the need for faster, more flexible, and cost-effective communication systems. Internet-based alternatives such as Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) have emerged as popular replacements for ISDN and PSTN. These new technologies leverage the power of the internet to deliver voice and data communications with superior quality, scalability, and a host of additional features. Whilst the forced migration is expected to happen at the end of 2025, these old lines will no longer be for sale by BT from September 2023.

Here are a few benefits you can expect:
