<p>The INVITE from w.x.y.z:44308 -> a.b.c.d:6060 is not

<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
