[SR-Users] topos: how to hide one side only

[Dmitri Savolainen]

I just want to hide intra topology from client: no any record-route, via
and contact headers except   kamailio_external_ip address for client. But
full client  record-route, via and contact for media_server(b2bua). Seems
it is necessary  use remove_hf / insert_hf with htable/redis as data
storage
