BT has announced it will be starting the PSTN and ISDN switch off in 2020 (next year). The gradual phase-out of the older systems will start in 2020 and no new orders will be taken from this point, what’s more, all lines will be completely removed by 2025.

Wondering what to do next? Whatever your question, we’ve got the answers:


What is ISDN?

Integrated Services Digital Network, or ISDN, is the original high-speed internet service. ISDN internet service is basically a telephone-based network system that operates by a circuit switch, or dedicated line. It can transmit data and phone conversations digitally over normal telephone wires.


Do I have ISDN?

Unless you’re using a cloud based solution such as VoIP or SIP it’s likely you are operating via ISDN. You will be able to confirm this by calling us on 0808 231 5373


Do I need to wait until 2020 to switch from ISDN? 

Not at all, there are already millions of businesses using cloud telephony to their advantage. Monthly costs for some customers have been reduced by up to 30%. Paired with the flexibility and agility a cloud solution can offer, it makes perfect sense to switch now.


What other solutions do I have?
