The first call appears to be rejected by your PBX but I think the  
debug is missing info.  The "Cause i = 0x81B6 - Incoming calls are  
barred" should probably appear in a Disconnect or Release message  
from the PBX.

The second one is also rejected by the PBX. I would guess because of  
the Display IE but the second Release message is a bit confusing.

Is this H.323 or MGCP?

We have a PRI between are CCM and Nortel M1 pbx. Was working fine  
until we upgraded.
We upgraded are CCM from 3.3.4 to 4.1.3 . Now we can't make any  
calls. the D-channel is established.
but when I try to make a call from my IP phone it disconnects right  
away. when I call from Nortel to IP
it rings once then disconnects. I did a debug isdn q931 and see the  
Messages.
Any help is appreciated
