So should I have to give the same treatment to
method=="CANCEL" as
method=="BYE"?
i.e.:
if (client_nat_test("3")) {
setflag(7);
force_rport();
fix_nated_contact();
};

Hi Alberto!
The BYE message from the client has no 'rport' paramter in its Via:
header. Thus, ser sends the response to the IP:port in the via
header. As there is no port, ser assumes port 5060.
You can manually add the rport paramter by using force_rport().
Then, ser will add the port from which it received the message
(61133) and will use this prot for responses.
