<tt>Hello Khaled,<br>
<br>
The only serious problem here is that you have a bogus trunk (as
SIP implementation) :).<br>
<br>
When the CANCEL is received by trunk (message #9) , it sends back
a 487 final reply for INVITE (message #11) - once it did that, not
other reply must be sent for the INVITE - but it sends also an 200
OK a bit later (see message #14) - which is completely wrong.<br>
<br>
Regards,<br>
</tt>
