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();
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!
