Ok. Thanks. I install 4.1.3 Kamailio and rtpengine as a daemon
rtpengine started as:
./rtpengine --ip=MY.PUB.IP.OF_Kam --listen-udp=127.0.0.1:7723 --listen-ng=
127.0.0.1:7724 --pidfile=/var/run/rtpengine.pid
Now I need to proxy rtp beween my clients and my asterisk then tow at the
public Net and this interfaces addede to dispatcher
At my configuration at kamailio i do this
modparam("rtpproxy-ng", "rtpproxy_sock", "udp:127.0.0.1:7724")
And for at routes to asterisk do this:
route[TOASTERISK] {
ds_mark_dst("P");
if(!ds_select_dst("1", "4")) {
sl_send_reply("500", "Service Unavailable");
xlog("L_INFO","[$fU@$si:$sp]{$rm} No destinations available
for $rd \n");
exit;
}
xlog("L_INFO","[$fU@$si:$sp]{$rm} From Outside World to Asterisk
Box $du\n");
rtpproxy_manage("cawei");
route(FINAL_RELAY);
exit;
}
route[FROMASTERISK] {
if(ds_is_from_list("1")){
rtpproxy_manage("cawie");
xlog("L_INFO","[$fU@$si:$sp]{$rm} Call from Media-Server
Cluster\n");
sql_pvquery("ca", "select received from location where
username='$tU'","$var(res)");
xlog("L_INFO","SQL query return {$var(res)} for {$tU}\n");
$du=$var(res);
return 1;
}
return -1;
}
route[FINAL_RELAY]
{
if (!t_relay()) {
sl_reply_error();
}
}
ar /var/log/syslog I see that rtpengine (as rtpproxy_offer) changing SDP c=
at incoming connections from address of client to Public IP of Kamailio,
and sucsessfully transfered this packet to asterisk and as rtpproxy_answer
stay with no changes this address, so client and asterisk know that they
must sent RTP packets tp kamailio for proxy rtp through kamailio.
I see only one warning
test rtpengine[3355]: Unknown flag encountered: 'symmetric'
after that i see at asterisk that it send RTP packets to kamailio (with
"via ICE"), but I see no incoming RTPpackets.
One thing make me confused me - rtpproxy_offer (at TOASTERISK route) adds
a=candidate with kamailio PUBLIC IP, I think that asterisk and client
things that kamailioo is STUN server (that is not write).
So I have 2 questions after this:
1. What about flag? Why rtpengine does not know it?
2. How send write stun from kamailio to client and asterisk?
