Again for the benefit of the list: The incoming message is a Setup-Ack but it is missing valid information in the H323-Message-Body. The "DisplayIE" indicates it is coming from another Quintum, problem is Quintum's do not send SETUP-ACK over IP, they do send CallProceeding however. So logic tells me the GnuGK is in between the 2 GW's and it is GKRouting (Proxying) the messages between the two. Ways to prove this out: 1. Have termination GW send a call directly to your A800 (via Static Route) and remove the GnuGK completely. OR 2. Sniff (w/Ethereal) on both sides of the GnuGK to see what the term side Quintum actually sends and verify that the GnuGK is changing this. OR 3. Set the GnuGK to GKRouting=0 and retest that way. I will see about making sure more adequate checking is done to verify that H323-Message-Body is missing/mis-encoded. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
