If you have an ISDN line you will need to consider new options for your business telephone communications such as VoIP (Voice over Internet Protocol).

Telephone services no longer have to rely on the degrading copper infrastructure from the past and instead, services can be provided using VoIP where your data transmits over the internet
However, for your new VoIP system to work, you’ll need a good quality internet connection so that your VoIP solution can run seamlessly.

If you’ve currently got an ISDN line, you’ll have to upgrade your telephony before December 2025.
