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.

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

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
