Re: [SR-Users] SIP-over-Websocket Load Balancing

Well, I do use them - so if you could explain in which table does Kamailio write the user's proto and which flags I can use - I'll make a test to see which scheme is preferable :) So, about script: 1.) Write to redis Please read http://kamailio.org/docs/modules/4.3.x/modules/ndb_redis.html this guide to understand how to connect redis to Kamailio It route[AUTH] you shall add write to redis command: if (is_method("REGISTER") || from_uri==myself) { # authenticate requests redis_cmd("protobase", "SET $fU $proto bar", "r"); # Here is the redis if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } You can find information about pseudo-variables on this http://www.kamailio.org/wiki/cookbooks/4.0.x/pseudovariables page 2. Rtpengine algorithm First of all, look through https://github.com/sipwise/rtpengine and http://kamailio.org/docs/modules/4.3.x/modules/rtpengine.html to understand what's the difference between rtpengine and rtpproxy In your NATMANAGE route change rtpproxy_manage(); or rtpengine_manage(); string to this: if(ds_is_from_list()) { xlog("L_NOTICE","====== selecting $tU proto\n"); redis_cmd("protobase", "GET $tU", "uproto"); xlog("L_NOTICE","===== $tU has proto $redis(uproto=>value)\n"); if ($redis(uproto=>value)=="ws") { xlog("L_NOTICE","===== $tU is a websocket user\n"); rtpengine_manage("direction=internal direction=external force trust-address replace-origin replace-session-connection ICE=force RTP/SAVPF"); } else { xlog("L_NOTICE","===== $tU is classy user\n"); rtpengine_manage("direction=internal direction=external force trust-address replace-origin replace-session-connection"); } } else { xlog("L_NOTICE","====== $fU proto is $proto "); if ($proto=="ws") { xlog("L_NOTICE","===== $fU is websocket user\n"); rtpengine_manage("direction=external direction=internal force trust-address replace-origin replace-session-connection ICE=force RTP/AVP"); } else { xlog("L_NOTICE","===== $fU is a classy user"); rtpengine_manage("direction=external direction=internal replace-origin replace-session-connection force trust-address RTP/AVP"); } } 2015-06-14 22:24 GMT+03:00 Juha Heinanen <jh(a)tutpro.com>om>: -- Alexandru Covalschi ABRISS-Solutions VoIP engineer and system administrator phone: +37367398493 web: http://abs-telecom.com/
