Hi! After a long search on maillinst, I'm trying to run SER with rtpproxy, for resolve problems with SIP UA (ata186) behind a nat, but I'm still get in trouble. I have setup ser.cfg to use rtpproxy, like this: ... if (method=="INVITE") { log(1,"INVITE\n"); fix_nated_sdp("1"); record_route(); force_rport(); setflag(1); force_rtp_proxy(); t_on_reply("1"); } ... onreply_route[1] { log(1, ">=====> reply 1\n"); if ((status=~"[12][0-9][0-9]")) { force_rtp_proxy(); } } ... But I get this error on syslog: 0(5463) ERROR: extract_mediaip: no `c=' in SDP I'm running rtpproxy, on linux shell without any parameters. Does anybody knows what this means that message, and how to solve, a ser.cfg for rtpproxy, and others tips will be helpfull... Regards. -- |o |o A prosperidade faz amigos.
