Discover how we can help you beat the BT ISDN Switch Off Date >

BT are switching off the PSTN and ISDN networks for good, starting with a cease of new supply by 2023 and moving to a full migration to IP before 2025. 

The BT switch off could affect thousands of businesses in the near future, especially those unaware of BT’s intention to phase out of technology. Traditional phone lines are a legacy technology with high maintenance costs and many drawbacks.

In Short, because of the BT ISDN Switch Off, during 2023 you will no longer be able to order any new traditional ISDN or PSTN services and by 2025 you must have totally upgraded to IP telephony to avoid interruption to your telephone services.

An amazing, professional, above and beyond service. We have recently moved over to Birmingham Telecom from another 3CX supplier. Where our old suppliers were terrible and misleading, Birmingham Telecom has been extremely helpful and forthcoming with any issues or charges that we would incur. Can highly recommend this company, massive thanks to Dan and Lee who have helped us out so much.

Our Company, The Phoenix Pattern & Tool Co Ltd, have been customers of Birmingham Telecom since they started out. They have replaced our phone system 3 times, recently bringing us into the 21st Century. The 3CX system that we have now is user friendly and the app enables working from home much more convenient. Special thanks to Andy for always getting the right product to suit us and Shaun for the time and effort put in with us during and after the installation, Dan and Lee for attention given quickly to any of our queries. A great job, I have no hesitation recommending Birmingham Telecom.

We have just signed to transfer over to Birmingham Telecom in the last week, the transition is not due to take place for a few weeks, but our phone and internet line was cut last week. This company setup an app-based phone system within a few hours getting us back up and running and receiving the calls. Amazing effort and great first impressions. Very positive, knowledgeable, and supportive staff.
