[c-nsp] Cisco 2600 and ISDN

Tue Sep 15 13:51:04 EDT 2009

I called the TAC but they won't help with this because they say they don't
support 2600's.

I have a central side 2600 with an ISDN BRI card in it, and a remote site
with a 2600 and ISDN BRI card in it.  I have the ISDN lines working, and I
have the remote site calling into the central site (I can see the calls on
the console) and RADIUS appears to be authenticating the call.  Then the
session drops with this:

Tue Sep 15 11:09:38 2009: DEBUG: Packet dump:

Can anyone detect any inconsistencies in the 2 router's configs below?

Thanks,
CJ
