Most ISDN calls require at least some knowledge about what equipment is at the other end. Before you can receive or make such a call you need to first save an entry in your Destinations list.
Click on the + icon.
In the first menu selector, choose Dialing Shortcut or to receive an incoming call, Incoming Shortcut.
Now select the correct format for the device to which you wish to connect.
In the next box, enter a name that describes the shortcut. e.g. Receive ISDN Call.
For outgoing calls, enter the ISDN number(s) for the destination in the last box(es).
Adjust the other settings as required...
Click to save your new destination.
You can now connect by simply clicking it in your main Destinations list. For incoming calls you will then be presented with the number(s) for the ISDN user to dial.
* Note that by default, Link+ is Auto-Accept only. Contact us to change this for use with ISDN.
