[Users] nathelper force_rtp_proxy onreply_route

hello, in SDP body sent out by the proxy the original media IP address is still present, the rtpproxy ip is added as a another line. is this the correct behavior ? should I add some flags to remove the original media IP ? for the invite this does not happen, the c= field is REWRITTEN with the ip received from the rtpproxy. message received by openser: ============================================ v=0. o=CiscoSystemsSIP-GW-UserAgent 4176 788 IN IP4 GW-IP-ADDRESS. s=SIP Call. c=IN IP4 GW-IP-ADDRESS. t=0 0. m=audio 17644 RTP/AVP 18. c=IN IP4 GW-IP-ADDRESS. a=rtpmap:18 G729/8000. a=fmtp:18 annexb=no. a=direction:passive. ============================================ message sent out by openser: ============================================ v=0. o=CiscoSystemsSIP-GW-UserAgent 4176 788 IN IP4 GW-IP-ADDRESS. s=SIP Call. c=IN IP4 GW-IP-ADDRESS. t=0 0. m=audio 35784 RTP/AVP 18. c=IN IP4 RTPPROXY-IP-ADDRESS. a=rtpmap:18 G729/8000. a=fmtp:18 annexb=no. a=direction:passive. a=nortpproxy:yes. ============================================ onreply_route block ============================================ if(status =~ "(183)|2[0-9][0-9]") { if(!force_rtp_proxy()) { log(3, "force_rtp_proxy FAILED"); }; }; ============================================ thanks Razvan Radu
