I am using kamailio+rtpproxy. while making a call from caller to callee through RTPProxy. Then why only callee able to listen caller voice . I use following script snippet. route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) { unforce_rtp_proxy("t"); } else if (is_method("INVITE")){ if (has_body("application/sdp")) { set_rtp_proxy_set("0"); rtpproxy_offer(); } } else if (is_method("ACK") && has_body("application/sdp")) { rtpproxy_answer(); } if (!has_totag()) add_rr_param(";nat=yes"); #!endif return; } By understanding ngrep RTPProxy has been attached to callee only. in short , In one to one call with Kamailio + RTPProxy. Only callee able to listen caller voice. While callee voice doesn't listen by caller. How can both party attached to RTPProxy.

Maybe you can share the relevant config snippets to see if we can spot something wrong there. Cheers, Daniel On 24.08.20 13:18, Amit Pal wrote: Dear Team , I am using Kamailio and RTPProxy for media.
