<p>The INVITE from w.x.y.z:44308 -> a.b.c.d:6060 is not given.
That's the one that is needed in order to match the CANCEL, which
comes from w.x.y.z.</p>
<p>Can you provide it?<br>
</p>
Cheers,<br>

<p>Hello,</p>
<p>do you have a pcap with all messages for such call
(invite, replies, cancel)? It is important to see if the
transaction matching elements are properly set.</p>
<p>In general, the rule for cancel is to be sent in the
same way (with the same elements) as the invite, because
cancel is not a standalone transaction, it must match
the associated invite one.<br>
</p>
Cheers,<br>
Daniel
