this is fine.

there is currently nat_flag and sip_natping_flag. sip_natping_flag is
used internally by usrloc and was not topic of this discussion.

my understanding was that if nat_flag has been selected from branch flag
range, then it will be automatically mapped to corresponding branch
specific message flag when lookup() is called so that it is possible to
check in branch route if contact of that branch is behind nat or not.
if that is true, then the same should be possible also for the new
flags (e.g. the proposed mediaproxy flag).
