The ISDN Switch Off may seem complicated, but it’s simpler than you think. When you work with Lily, we’ll answer all your questions and solve any worries. 

For now, we’ve responded to your top 5 questions that’ll clear some confusion and prepare you for the digital transformation. 

  1. What is the ISDN Switch Off?

The ISDN Switch Off refers to BT Openreach’s nationwide phase out of ISDN and PSTN services. Residential and business properties will use newer technology, including hosted phone systems and fibre broadband

  1. What is the PSTN and ISDN?

The Public Switched Telephone Network (PSTN) is a communication network that uses copper lines to support phone calls. The Integrated Services Digital Network (ISDN) is a digital communications system that transfers speech and data over the PSTN. 

  1. Why is the ISDN Switch Off happening?

The ISDN and PSTN infrastructure has become obsolete and difficult to maintain. It no longer supports our digital world and lacks the flexibility, cost-savings and efficiency a fibre network provides. 

  1. What is the meaning of stop sell?

Stop sell refers to areas that can no longer buy or sell Wholesale Line Rental (WLR) products. These include analogue or ISDN phone lines. The final stop sell ended in September 2023. Businesses can continue to use WLR products until they’re withdrawn in 2025.

  1. What is the best replacement for my current phone system?  

A Voice over Internet Protocol (VoIP) phone system allows you to make calls over the internet. A hosted phone system offers a range of modern features that’ll boost productivity, cost savings and flexibility in the workplace.
