Well the line is in our lab since ages, so i can't really tell you
what "exactly" has been ordered back then :-)
It's an EuroISDN-BRI without a MSN but an unbounded number of
DIDs(Fixed 7-digit Headnumber plus up to 5 digit extensions - which is
basically a standard BRI-line in Austria).

As the outbound calls work fine(headnumber+extensions are delivered) i
assume it's not exactly an configuration issue.
According to my colleagues the DID has always been sent(With proprietary PBX).

A few harder facts - my configuration:
This in old paste of a previous problem, but the configuration is
still the same. If i can provide you with more precise information,
please let me know what you need, a ISDN-trace is in the paste in my
previous mail.

I'll run a test on a different box with a Sangoma card tomorrow, i
just hoped someone could give me a jump-start with the information i
posted earlier.
