thanks for fas reply. If I may user rtpengine as rtpproxy maybe you already use it or just know - does rtpengine provide ridge mode as rtpproxy between internal and external interfaces? At my instalne if I add rtpengine --ip=my.ext.net.addr/my.int.net.addr It shows that ip if wrong, but I neet proxy rtp between interfaces. Thanks. 2014-07-03 13:02 GMT+04:00 Dani Kamailio <dani.kamailio(a)gmail.com>om>:

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? 2014-07-03 23:46 GMT+04:00 Andrew Pogrebennyk <apogrebennyk(a)sipwise.com>om>:
