Which would seem to indicate I am out of B channels on my PRI. But... show isdn service gives me:
filet-rtr#sh is se PRI Channel Statistics: ISDN Se1/0:23, Channel [1-24] Configured Isdn Interface (dsl) 0 Channel State (0=Idle 1=Proposed 2=Busy 3=Reserved 4=Restart

I'm stumped. Can anyone out there help?
