Dear Daniel,

                    I am just changing my environment. 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.

Regards

Hello,

depending on the direction, you may have to use stream to uac function, I can see you use only stream to uas function.

Cheers,
Daniel

                rtpproxy_stop_stream2uas();

            };

                }else {

                t_on_reply("2");

        }

 if (is_method("ACK") && has_body("application/sdp")) {      

                                rtpproxy_answer();

}

#ON REPLY ROUTE

onreply_route[1]

{

    if (has_body("application/sdp"))  {   

                                set_rtp_proxy_set(0);

                                rtpproxy_answer();

                }

}

onreply_route[2]

{

    if (has_body("application/sdp")){

                rtpproxy_offer();

                }

}

Please guide what is wrong here.

Thanks

Hello,

that typically happens when you try to play to the callee before knowing where it expect the RTP (before getting response with sdp for INVITE). Maybe you can share the relevant config snippets to see if we can spot something wrong there.

Cheers,
Daniel

Dear Team ,

                    I am using  Kamailio and RTPProxy for media. I am trying to play caller/callee side  media by rtpproxy_stream2uas/ rtpproxy_stream2uac.

But I am getting error
