It works as I expected:

- The CANCEL arrives to Kamailio (1.5) with Totag (bug in UAC).

- Kamailio does t_relay() for the CANCEL without checking
loose-routing or Totag (CANCEL threatment is now above loose-routing
section).

- Kamailio replies 200 to the CANCEL and generates its own CANCEL (of
course with no Totag).
