HI if I use engage_rtp_proxy(), I can use it only on initial INVITE and opensips should automatically rewritten also 200 OK and ACK with SDP, right? But when I am using this function, I can see from trace that only SDP for initial invite is rewritten, 200 ok with sdp is not changed. Must I do something else? Rtpproxy is not running in bridge mode. tnx miha
