[cisco-voip] Problems with incoming ISDN call / CME does not process the call -> any clou? q931 debug inside

[Brian Meade]

For the first one, you're getting a facility message instead of a setup
message which is strange.  Are you sure you caught the beginning of the
call?  I'm not aware of any ISDN switch-types that would use a Facility
message for initial call setup.
