Hi Gert.

I did come across that as a possibility to look at while debugging.

But the bearer cap (0x8890) and everything I see reported in debug isdn
q931 on all BRI/PRI interfaces on all devices indicates it has established
a 64k circuit.

Im starting to think its just not possible. Maybe the VIC doesnt properly
handle bearer caps beyond those used for voice?

I need some ISDN debugging tools. :-)
