Hi,<br><br>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,<br> <br> CSeq: 3 ACK<br><br>
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.<br><br>Thanks,<br><br>
