How Will The 2027 Landline Switchoff Affect My Businesses

  • ISDN is going – Everybody needs to move to a version of SIP or VoIP for their voice connectivity.

  • Implications of analogue lines – They are part of the WLR network and in line with the key dates, analogue will no longer be available after 2027

What is the ISDN Digital switch off?

The Openreach ISDN switch off announcement in 2015 made it clear that they would stop taking new ISDN orders in 2020, with a view to switching-off and deactivating its ISDN network completely in 2027. This means that all copper services currently used for voice will stop working from this point – ISDN, PSTN and Multi-line. The copper will remain but just for data services like FTTC, which is fibre from the green cabinet and copper to your premises.

The telephone network in the UK has been in use since 1876 and has become old, tired and increasingly costly to maintain or to fix when things break. It is being replaced with modern technology fit for the digital world we now live in.

Does this affect me?

If you have a phone system that was installed more than 3 years ago and you have the ability to take more than one call at a time, it’s likely that you will be using an ISDN line to communicate with the rest of the world.

Depending on your provider, there should be a reference to ISDN on your bill. Unfortunately, many telecoms companies make customer bills difficult to understand or they hide the information in different text. If it is unclear if you are using an ISDN or PSTN line then reply to the email and we will be able to tell you quickly whether you are using an ISDN line or not.

Currently there are 3,000,000 businesses still using ISDN lines. You might think because your are not with BT this doesn’t affect you but unless you are direct with Virgin you will be using a BT phone line. If you know you are in the cloud, using SIP lines or on a VOIP system the good news is your already set for the change. If VOIP cloud or SIP do not look familiar to you there is a strong chance you are on the old technology and need to start looking into moving over ASAP before prices increase.
