ISDN lines replace traditional analogue lines, delivering clearer and sharper calls and faster data connectivity to your business.  Each ISDN channel, lets voice or data traffic travel over its digital connection, allowing you to do more, such as have concurrent calls or a dedicated internet or fax line and a phone line.


ISDN2 lines are ideal for business with 2 to 8 employees, as you can add or remove channels, in pairs, up to a maximum 8 channels to suit your business needs.

Each channel can be configured separately. This allows you to tailor your connection to your business, including having different phone numbers for various phones and devices, double up channels for a faster internet connection or allow simultaneous incoming and outgoing calls.

If you have a phone system your DDI’s will work as normal.
