The ISDN shutdown in Germany, has sparked ‘panic among many firms that did not prepare early enough’ for the switch off.. Germany is one of the first countries scheduled to switch off their traditional analogue and ISDN trunk lines on 31st December 2018.

Businesses are urged to act ahead of the BT switch off in 2025, sooner rather than later. Although it may seem a long way off – on the contrary, now is a good time to get your business communications changed over to avoid rushed decisions closer to the deadline.

BT will also no longer accept any new orders or amendments to services applicable to any ISDN products as of 2020.


“Germany is one of the first countries to switch off traditional analogue and ISDN trunk lines and according to Klössner UK comms players would do themselves a big favour by acting now to offset potential customer issues ahead of the UK’s ISDN switch-off in 2025.”

“A number of German businesses that were not aware of this change and how it affects them are in a state of panic as they heavily rely on their ISDN service to function.” he stated.

“This can drive business owners to make quick decisions about something which could have a long-term costly impact on their sustainability. Educate your customers on the flexibility and efficiency of new functions from migrating to a SIP solution.” – Axel Klössner, COO and International Business Director at German vendor Auerswald


Here’s the good news. Swapping your lines from ISDN to SIP couldn’t be easier. Better yet, SIP trunks offer a much more flexible and lower cost alternative to ISDN for inbound and outbound voice calls for your business.
