Hello,
if you want to rely on kamailio to memorize where to send the following register, the hash table is the right tool.
Cheers, Daniel

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!
