The ISDN Switch off-how does this affect your business?

In 2025, BT will be switching off all of their ISDN and PSTN networks to replace them with IP voice services. However, since 2020, they have been gradually phasing out those services and already BT have ceased taking IDSN borders, so this is now forcing businesses to review their communications and find IP options for their telephony.

What is PSTN and ISDN?

Public Switched Telephone Network (PSTN) is the analogue voice communications that we would all have been used to and was a reliable method of making calls all over the world. Integrated Services Digital Network (ISDN) was its successor. This allowed digital transmission of voice, video using the PSTN network.

Systems are now out of date, so BT has decided to phase them out, and the running and maintenance costs of running these have become untenable. Whilst they have been updated over the years, the set up and design is exactly the same as the original phone lines which were originally implemented in the 1800’s. As technology has accelerated considerably, it is now about time for the telecoms systems to do the same.

In many respects, it’s still unclear for many businesses that this is even occurring, but change is coming, and all businesses need to embrace that it’s time for them to embrace new technology, otherwise pretty quickly, they’ll be left without a phone system.

The ideal choice is SIP and VoIP, but what are they?

Session Initiation Protocol (SIP) and Voice over Internet Protocol (VoIP) implementation means you can make voice and video calls using across mobile devices and computer with the use of the internet connection.

The greatest benefit of using SIP rather than ISDN us really the cost benefit that it provides businesses, as calls between users are free! VoIP telecommunications is often referred to as Cloud Communications, meaning that you are using all communications tools-calls, video conferencing, instant messaging, by entirely using the cloud.

What about the 5G Countdown

Cloud technology can help protect businesses against the ISDN switch off. However, and 5G cellular technology is also coming! This offered increased bandwidth an over a gigabyte per second in data rates and will match internet speeds of fibre connections.
