I'm trying to use an 803 on an ISDN line that's point to point not point to multipoint, but I can't find out how to do it. If I use a standard type config (listed below) it doesn't connect, but then I didn't expect it to! Does anyone know what I need to change to make it work with a point to point line?
("Point to point" might be a UK term. It's the type of ISDN line you usually connect your phone system to, as opposed to "Point to multipoint", which is the usual domestic ISDN line.)
Any help much appreciated!
When I try to dial the debug output is:
