Re: [SR-Users] routing SIP REGISTER with app_perl

Hello, I'm learning Kamailio. My ultimate goal is to be able to route SIP messages from User Agents to specific FS boxes. I'm starting with routing REGISTER messages. I used app_perl to randomly lookup one of the FS box's IP Address from postgres database, then I stored the IP in avp and then in hash. It seemed like overkill but it was the only way I could keep the FS IP address in memory between the first REGISTER and REGISTER with Auth. my app_perl script sets the IP as follows: my $sth = $dbh->prepare("SELECT ip_address FROM host_machine WHERE is_online = true ORDER BY random() LIMIT 1"); $sth->execute(); my $host_ip_address = $sth->fetchrow(); Kamailio::AVP::add(10, "sip:$host_ip_address:5060"); And here is my kamailio.cfg for REGISTERs route[REGISTRAR] { if (!is_method("REGISTER|PUBLISH")) return; if (is_present_hf("Authorization")) { add_path_received(); $avp(i:10) = $sht(a=>$ci::dest_server); avp_pushto("$du", "$avp(i:10)"); } else { perl_exec("random_server"); avp_pushto("$du", "$avp(i:10)"); $sht(a=>$ci::dest_server) = $avp(i:10); } t_relay(); exit; } "random_server" is the perl script to get the FS IP address... Seems crude but works... I'm sure there is probably a more elegant way to do what im trying so any advice and criticism is appreciated, thank you! /V _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
