John,
This function can be used to check the direction of every message:
http://kamailio.org/docs/modules/4.0.x/modules/rr.html#idp223296
You might also need to append the record-route parameters to remember
the flags you have passed to the manage_rtpproxy() initially.
Based on the direction of the request and initial flags you can
determine what flags to use when calling manage_rtpproxy() for a given
in-dialog requests and reply.

Hope this helps.
Andrew
