Hi,
How does one determine which part of a SIP conversation an ACK packet is
responding to? I would have guessed that it would be in tne CSeq, but that
field just says, for example,
CSeq: 3 ACK
The only method I have come up with so far is looking at the source and
destination ports + the destination of the Request-LIne and try to determine
the most recent message it might be responding to.
Thanks,
Mark Price

What for do you need it? Inside openser.cfg or just manually SIP debugging?
Openser does not need to know to which transaction an ACK belongs. If
you need it, you can use the dialog module and see if it matches an
existing dialog. Just compare callid, totag, fromtag and cseq.

CSeq: 3 ACK
This ACK matches the INVITE transaction with same callid, totag, fromtag
and CSeq = 3.
