Hi,

   My name is Ionut and I am a new developer in VoIP dev team in 1&1. Maybe you 
can help me with the following problem. I have the following scenario: UAC 
sends invite to UAS via Kamailio proxy, UAS responds with 491. I am trying to 
catch the ACK from the UAC in siptrace module using TMCB_ACK_NEG_IN. I 
successfully trace this message but there's one more unwanted call to this 
callback. It gets called for an INVITE request which I don't want to trace 
since the callback is called ACK_NEG_IN. From my understanding, this call is 
issued right after the ACK is sent to the UAS, which, for me, doesn't seem to 
be correct, since the callback should trace in ACKs not outs. TM code that's 
calling this callback is in t_reply.c:2291. Is this a bug? I can fix this issue 
easily in my code by checking whether or not the current message is an ACK in 
siptrace but it would be great if we would work for a fix to this issue.


Regards,

Ionut
