Hello Khaled, The only serious problem here is that you have a bogus trunk (as SIP implementation) :).
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.
