The ISDN Switchoff-what does this mean for your business?


The Impact of the ISDN BT Switch-Off

In 2015, BT announced that their Integrated Services Digital Network (ISDN) and  Public Switched Telephone Network (PSTN) lines will be switched off by 2025.


PSTN is considered traditional telephony : it allows calls

to be made over copper and fiber telephone lines using analogue signaling. However, PSTN and ISDN are aging technologies, becoming harder to maintain.


In the last decade, broadband services have increased in reliability and quality and the PSTN has evolved to support this change to an almost completely digital network. As a consequence, traditional fixed line telephony using analogue services for calls have become obsolete.


Now, it’s all in the cloud. Cloud-based services eliminate the need for phone lines and provide the communications that supports your hybrid working.
