The fast busy (reorder) usually is a telco problem, I think this indicates
the trunk group the call is supposed to be delivered to is out of service.
It seems to me the last time we had this problem, someone at the CO had
left a loopback plug where it didn't belong. I don't know about your
carrier, but we usually need to call three or four different departments
at the telco to get a PRI turned up.

Have you done a "set debug isdn" and "set console" to watch the D channel
messages? Does the session counter show any calls when you do a "show
isdn"? If the call is even getting to your equipment, you should see
messages on the D channels, if they are up.
