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.
regards,
klaus
