BT 2025 ISDN SWITCH Off
Does this effect me ?
If you are curious to discover how BT’s ISDN line cease will impact your business, you are in the right place.
PSTN and ISDN really are old technologies now. PSTN is the same phone line most people have at home (unless you live in a relatively newly built house) whereby analogue voice data flows over circuit-switched copper phone lines.
Maintaining multiple legacy networks is very expensive for BT. By converging all services – voice, data, video, and even broadcasting – to the IP protocol, BT only has to maintain one network, not several.
In a nutshell, BT is moving its entire voice network to voice over IP (VoIP) with the PSTN now being switched off in January 2027 a change from the originally planned December 2025.
What should you do ?
Businesses haven't been able to buy any systems that use PSTN or ISDN since 2020.
January 2027 is less than 2 years away so if your current traditional telephony contract is up for renewal within the next 12 months or you wish to embrace the latest technology, now is the time to start exploring the benefits of VoIP and SIP technologies.
Is your internet connection good enough to deliver VoIP?
