incoming_hih scenario is sending this header inside file
scenarios/incoming_hih/sipp_scenario00.xml
This means, the caller do not wish to rely his
history info information to the callee.
This has been implemented with commit
743e05b642adbd05c935ad794b2e60ee91fbb222.
Thanks to this, KCT now must check that the
History Info header is anonymized without
showing the real caller.
