Is your business ready for ISDN Switch Off?

What is the BT ISDN Switch Off?

What is the BT ISDN Switch Off and why is it important not to ignore it? The BT ISDN Switch Off is here, and it has been announced in 2015. From 2020 you will no longer be able to purchase ISDN lines with a target date of 2025 for a switch off date. With over 2 million UK’s businesses still running their telecoms on traditional ISDN telephone lines, these businesses are now wondering what their options are. Read on to understand why this is so important and how to get prepared for ISDN Switch Off.

What’s the ISDN line?

Is your businesses still make calls through the ISDN (Integrated Services Digital Network)? ISDN was launched in 1986, marking a transition from land-line devices to digital, as it enables data and voice to be sent at the same time. At that moment, it was the ideal method for businesses that had to send data and voice simultaneously. But now, it is a perfect time for switching from ISDN to a modern, more reliable and affordable technology. We offer a wide range of solutions, and we are happy to explain how to future-proof your business with brand new telecoms.

Why are ISDN lines being phased out?

British Telecoms have shifted their focus from analogue systems to digital systems, and by 2025, they will focus on digital systems only. That means that by 2025, they would have entirely switched off the ISDN network, and migrate to digital voice services. British Telecoms do not supply ISDN services anymore, so new customers cannot request new ISDN collections (which started in 2020). For many years ISDN was a cutting edge technology; today, it has become outdated, and new technologies offer much more advantages than ISDN can offer.

The disadvantage of ISDN lines

ISDN lines are not flexible and can hardly be tailored to special business requirements. ISDN lines are expensive to maintain and have complicated hardware, as well as software. Also, it is expensive to maintain and involves setting up firewalls that could cost your business lots of money. ISDN lines are often out of your control, leaving you at the mercy of suppliers. You cannot quickly implement changes that suit your evolving business needs. Such instability could get you disconnected from your customers and other businesses. With our experience and expertise, we can help your business with a seamless transition from old fashioned ISDN telephony to modern VoIP phone system.

What is replacing ISDN lines?

In simple terms, ISDN is migrating from digital to internet-based services called SIP and VoIP. In 2025 all the calls will be carried over your broadband – the Internet connection. It is the best time to invest in your business telephone system, especially when you compare the disadvantages of the ISDN to the benefits of modern technology like VoIP. Anyone left with ISDN service in 2023 will have a very limited set of options as to what they can do with them. We do recommend you to migrate your telephone system to VoIP phone system as soon as you can.
