BT is switching off their PSTN & ISDN network in 2025

Have you heard BT is switching off their PSTN and ISDN network in 2025?

BT has boldly announced its intention to switch off their PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) network in 2025 in favour of VoIP (Voice over Internet Protocol) voice services. The phase-out will begin in 2020. At this point, BT will cease taking ISDN orders. UK businesses will be positioned to upgrade their business telephony systems and services to a mature VoIP telephony solution.

What is PSTN and ISDN?

PSTN is commonly referred to as a basic single analogue telephone line that is primarily used for making voice calls, connecting to fax machines, payment terminals and connecting to a router for internet connections such as ADSL2+ (Asymmetric Digital Subscriber line) and FTTC (Fibre To The Cabinet). PSTN technology is extremely old, used by millions of homes and small businesses throughout the UK who only need one telephone number, the ability to make or receive one concurrent telephone call and for UK broadband services mentioned. Generally speaking, PSTN lines do not require a PBX (Private Branch Exchange) known as a business telephone system and are gradually being phased out with the introduction FTTP (Fibre to the Premises) and hosted VoIP telephony services.

ISDN requires a PBX telephone system fitted and is often more expensive compared to a VoIP hosted phone system. ISDN carries voice and data services over copper PSTN lines in a digital format which provides better voice quality. In the UK, British Telecom (BT) provides ISDN2 as well as ISDN30. ISDN2 enables two concurrent telephone calls at the same time over one PSTN line but can be expanded up to 8 telephone lines. ISDN30 is used by businesses that require 10-30 lines or more. Both types of ISDN lines include the option of adding DDI (Direct Dialling In) numbers that are used with a PBX to provide staff with individual numbers that allow callers to bypass the operator and be directed straight to the required extension. As businesses gain access to better quality broadband services, ISDN lines will fast be phased out as organisations adopt a more cost-effective, efficient way of working with a proven hosted VoIP phone system that just works!

Why are PSTN and ISDN telephone lines being phased out?

Simply put, BT has acknowledged that these systems are out-of-date so they have decided not to invest any more time and money on outdated technology. The next step for businesses to take is to invest in a VoIP hosted system which will enhance business operations for now and well into the future.

Did you know?

As of 2017, over 2 million businesses still use an ISDN connection in the UK, all of which are affected by the upcoming switch off.

A 2017 survey has also shown that a quarter of the UK’s businesses are still unaware that the great BT switch off is even taking place.

With time running out. Businesses need to be made aware of the upcoming changes so they can take action and begin the necessary switch to a VoIP hosted solution today!
