Hi George,
There are two cases you are referring at:
1) flags inheritance by the replies (set flag in INVITE and see it in
replies) - is this working?
2) flags inheritance by the CANCEL (set flag in INVITE and see it in
CANCEL req/reply) - this is know not to work as so far the CANCEL was a
different transaction then the INVITE, but starting with 1.3 it is the
same, so it should be fixed.
Regards,
Bogdan
