All You Need To Know About the BT ISDN Switch Off
As our lives change and our requirements become greater and more immediate, the need for legacy technology, and outdated systems, to be replaced, in order to keep up with our demands, has become more vital than ever. From the technology we use in our personal lives, be it smartphones, wearable technology such as watches, or even household appliances that use the internet to offer customers new features, right the way through to businesses who use networks, reliable internet connections, and a host of other modern technology to function on a daily basis.
This shift and change are happening everywhere but, in particular, it is going to become prominent across the telephone networks of the UK. Known as the ‘BT ISDN Switch Off’, this huge shift in the way people make phone calls will happen in 2025 and it is vital that, for business continuity, companies learn about it and make the necessary changes now to avoid having to play catch-up in a few years.
Here at Prestige Telecom Group, we are driven to ensure that, over the next few years, the millions of businesses that operate in the UK are made aware of these new VoIP-style systems and the urgent need for them to work with business telecoms experts now, so they are ready for when the big switch off happens in 2025. This drive has led us to create this page on our site which is a comprehensive look at this topic and aims to cover absolutely everything you could ever wish to know about the 2025 ISDN Switch Off, also known as the ‘BT Switch Off’ or ‘Copper Turn Off’.
On this page, which is split into sections, you’ll find all sorts of information, from the history of ISDNs, right the way through to the reasons behind it, and what you need to do now to make a success of the ISDN lines switch. Once you’ve gone through this content, you’ll feel confident about what to do next which, we hope, will be to pick up the phone to our expert sales team here at Prestige Telecom Group to talk about our business telecom solutions, business mobile broadband internet connections, virtual landlines, and VoIP systems – all of which can help you migrate to a fully-hosted cloud system.

From specific dates that you need to keep in your diary, right the way through to a history of ISDNs, how we came to use them, and why we need to replace them – we really will cover it all. But, to kick things off we thought we’d provide you with a summary of the ISDN switch off so that you have all the important information needed immediately to hand. As always, if you have more questions, feel free to get in touch with us and we’ll happily talk you through this pretty significant telephony event. Now though, let’s take a look at the plans.
The great BT Switch Off, as it is colloquially called, began way back in 2015 when this national institution made an announcement that they would be effectively turning off ISDN (Integrated Service Digital Network) and PSTN (Public Switched Telephone Network) lines and switching to digital lines, or internet lines. This means that from 2025 onwards, people won’t make calls using these analogue lines and instead switch networks to new IP technology, and SIP technologies, that are faster, clearer, and come with a host of new features.
Why Are BT Switching Off ISDN, Anyway?
The reason behind the switch off is simple, but fundamental to the smooth running of the nation’s telephony network. Essentially, it is happening because technology has become such a huge part of everyone’s lives that the traditional copper network that is used to make and receive phone calls can’t keep up with faster, slicker alternatives. ISDN and PSTN copper lines were introduced way back in 1986. To date, that is over three decades ago and, while regular maintenance and upgrades to the physical lines have been made by BT, the pace at which IP phone systems have become more developed, popular, and cost-effective has meant that no matter how much telephone system maintenance occurs, this outdated landline technology could never have kept up. The announcement in 2015 was BT acknowledging this and pledging to increase its investment in replacement products, such as VoIP services, which run on fibre optic connections and provide a greater experience for users, especially businesses.
Who Is Set To Benefit From The Switch Off?
From a selfish point of view, BT now has an opportunity to save money over time because they only have to manage one platform that has advanced functionalities and will be used way into the future, which will help keep costs down as systems become more popular, and cheaper. They also don’t have to spend vast sums on maintenance or deal with the hassle of travelling the country fixing old landlines that aren’t up to scratch. For companies, this switch presents an opportunity to become a genuinely remote organisation that isn’t tied down to an on-premise telephony network. A key problem with these traditional phone lines is that they are fixed to certain areas meaning people had to use them to make phone calls. Now though, because of the explosion in internet usage, people no longer have to rely on physical phone lines and can use business mobiles to make mobile calls from wherever they are in the world. The switch means they can take advantage of VoIP, virtual landlines, and other fibre products that allow them to make telephone calls.

What follows is a brief description of our main services, those that relate most heavily to the 2025 BT Switch Off.
Standing for Voice over Internet Protocol, VoIP will soon be the default way people and businesses communicate. This type of phone system frees you from an on-premise phone system that restricts your ability to work outside of the same four walls. Rather than speaking to someone over a standard phone line, on public telephone networks, VoIP allows you to communicate verbally with people over an internet connection, on a cloud network. Virtual phone lines that are held over an internet protocol (IP) lead to clearer call quality regardless of geography, as well as a range of other features such as automatic call routing, and brand-specific on-hold music.
Another great solution, that frees you from the office, a virtual landline is a business telecoms solution that makes it look, to customers, like you have a normal landline. However, this ‘office number’, once dialled, automatically redirects to the mobile phone or internet-connected device of a person in the business who has been assigned to answer it. The great thing about a virtual landline is that it can be answered from anywhere in the world while still appearing as if you have an office number. With a virtual landline, you can rest easy knowing that your customers only ever have to dial, and/or remember, one number the next time they need to contact your business.
Supplying teams with business mobiles ensure they can always be reached by you or their colleagues no matter where they are during business hours. As we head toward the big switch in 2025, the reliance on business mobiles will become even greater as businesses move away from traditional channels of communication, such as regular landlines, to more disparate forms of communication – devices that can be found in your pocket, not your desk. It’s important to ensure business mobiles are prevalent so that employees aren’t relying on their own devices which may be old and feature out-of-date technology. Business mobiles ensure people are taking advantage of the latest tech and remaining professional when on the phone.

Narrowband ISDN was an attempt to modernise the existing ISDN system by making it more digital, as opposed to its current analogue system. While well-intentioned, Narrowband Integrated Switch Digital Network (shortened to N-ISDN) did ultimately fail and become obsolete. It became so because it took far too long to agree upon a standardisation process, and, by the time it had been agreed, the technology that was initially put forward had become obsolete – a reminder of just how quick telephony solutions can change, improve, and adapt. The ‘narrowband’ refers to the use of communications, connections, and telecommunication tools across a narrower band of frequencies in any given communication channel, and is commonly used to carry voice data over a frequency set.
Known as an ISDN terminal adapter, it is a piece of technology that is used to stop a dial-up Integrated Services Digital Network line and instead connect it to a computer or LAN (Local Area Network). An ISDN adapter would be used by a business or consumer when they don’t have a dedicated ISDN telephone connection or sufficient computing equipment, they can sometimes be referred to as ISDN modems. The adapter transmits digital data directly from the computer to the specific ISDN line without having to switch between analogue and digital signals. This kind of equipment plugs directly into the serial port of your computer and acts like a modem.
Even in today’s world of superfast broadband, ISDN is still pretty quick. A typical line will run anything between 144 and 192 kbps (Kilobits Per Second), this can be increased by integers of 64kbps. It’s not that ISDN isn’t fast, it’s just the fact that broadband suppliers have advanced their technology to offer even quicker products, hence the ISDN Switch-off taking place in 2025. When it was first introduced, ISDN was the fastest connection solution out there and allowed businesses to take advantage of fast broadband, it surpassed dial-up and the more analogue rivals in no time at all.
An ISDN is an Integrated Services Digital Network that carries internet connectivity over specialist lines. A Digital Subscriber Line (DSL) is a connection that is ‘always-on’ and does not need to dial over the lines that it uses. The main difference between these two is that, with a DSL, a user can make calls while connected to the internet because the DSL does not need to dial out. This is unlike an ISDN, which does have to in order to create a connection and allow the data to flow through it. Another key difference is that DSLs use existing telephone lines and modems, whereas ISDN lines have to be installed and require adapters at both ends of the line. ISDNs must also be directly placed into the home business where it is being used.
Yes, ISDN, while being phased out and switched off in 2025, is still used today by plenty of people and businesses. ISDN is predominately used where broadband internet isn’t an option. Further, there are plenty of reasons why people choose to still use ISDN. For instance, it offers multiple digital services that operate through just one copper wire, it can connect devices and allow them to operate over one wire, and provides a higher data transfer rate. While plenty of providers and teams use it, time is ultimately going to see the use of ISDN end.
