<p>Ahh, I read first the initial email and already I responded to
it, so ignore that one -- anyhow, there should be good hints for
someone facing similar situation.</p>

<div>There was a code change in a recent version of PJSIP that
resulted in the second Via header not including the src port
that the request originated from. Effectively this meant that
the Via header was not an exact match for the invite, which
caused the transaction to not match. Through some
configuration changes in PJSIP I was able to work around this.</div>

<div>Trying to debug an issue with canceling an invite. I
have two different types of clients. On one client,
canceling an invite works correctly. With the other
client, it t_check_trans fails.</div>
<div><br>
</div>
<div>Both clients show the same request/responses:</div>
<div><br>
</div>
<div>On Client A:</div>
<div>-> INVITE</div>
<div><- 183</div>
<div>-> PRACK</div>
<div><- 200</div>
<div>-> UPDATE (from successful STUN binding)</div>
<div><- 200</div>
<div>-> CANCEL</div>
<div><- 200</div>
<div><br>
</div>
<div>
<div>On Client B:</div>
<div>-> INVITE</div>
<div><- 183</div>
<div>-> PRACK</div>
<div><- 200</div>
<div>-> UPDATE (from successful STUN binding)</div>
<div><- 200</div>
<div>-> CANCEL</div>
<div><- 481 (this is sent from my kamailio script
when t_check_trans fails)</div>
</div>
<div><br>
</div>
<div>I can't see much that's different between the leading
requests/responses of each. They seem to be virtually
identical (with the exception of IP addresses and tag
values, of course). This makes sense, since they're both
based on PJSIP (albeit different versions of PJSIP, but
not off by much)<br>
</div>
<div><br>
</div>
<div>Is there anything in particular I should be looking
out for that might be obvious? I could provide more
detailed logs and traces if required.</div>
