What Is ISDN?

ISDN is a common form of data transmission established in the 90s that sends information over copper wire systems. It is used by many millions of businesses across the UK. Often found in small businesses, ISDN sends digital messages through a landline using an adaptor or converter. Messages can then be transmitted to customers and clients through the internet. While it has been phased out in most private homes in favor of mobile technology and broadband, ISDN likely remains the primary method of making phone calls for your business.

The ISDN switch-off is going to happen in 2025. British Telecoms (BT), the UK’s largest telecommunications provider, will cease to operate all its legacy services. This means the infrastructure that used to enable old-fashioned landlines systems will no longer be operational. The result of the ISDN switch-off is that anyone currently using phone call data through ISDN will no longer be able to do so. The technology will become completely obsolete.

You have two main alternatives:

SIP

SIP uses virtual phone lines rather than physical lines like ISDN. It is the best alternative solution if you have an on-premises phone system.

This is mostly down to the flexibility it gives you, the speed in which you can add/remove lines, the quality of the calls, and the lower call costs.

You may not even have to change your existing phone system as most systems are compatible with SIP.

If you have ISDN lines and don’t want to commit or retain an on-premises phone system, then a Hosted IP phone system would be the best solution.

Hosted VoIP
