I determined that it was Setup-Ack based on additional trace I asked User-User to run (see msg below). This log was not sent to the User group but directly to me. Q931 Message type 0xd is "Setup-Ack", I determined that the term side is a Quintum based on the fact that the DisplayIE is "Tenor-Gateway". Like I've said the Quintum products don't send Setup-Ack. It looks to me as if somehow CallProc from term side Quintum is converted to Setup-Ack but DisplayIE is kept in the message. I am not familiar the "players" in this user group but perhaps someone who has written the GnuGK code can comment on this to verify what I am seeing. In any case the problem has been narrowed down and its just a matter of determining the correct course of action to resolve the reset.
