Dear Binan Yes, It’s my setting. route[nat_fixups] { #---- RTP Proxy handling ---# if (is_method("BYE|CANCEL")) { unforce_rtp_proxy(); } else if (is_method("INVITE")){ #---- Activates the RTP Proxy for the CALLEE ---# rtpproxy_offer(“cowf”,”202.55.233.194”); }; # catch and fix replies t_on_reply("2");} onreply_route[2] { #xlog("incoming reply\n"); #---- Handling of the SDP for the 200 or 183 reply ----# #---- If behind nat (flags 5 or 6) start RTP Proxy ----# #---- Activates the RTP Proxy for the CALLER ----# if ( is_method("INVITE") && (isflagset(5) || isbflagset(6)) && has_body("application/sdp") ){
rtpproxy_answer(“cowf”,”202.55.233.194”); } #---- If the CALLEE is behind NAT, fix the CONTACT HF ----# if (isbflagset(6)) { fix_nated_contact(); search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes'); } exit;} ThanksNick From: users-bounces at lists.opensips.org [mailto:users-bounces at lists.opensips.org] On Behalf Of Binan AL Halabi
