Here is is the relevant section of kamailio.cfg
$var(tempfU) = $fU;
#!ifdef WITH_IPAUTH
if((!is_method("REGISTER")) && allow_source_address() && $au == "")
{
# Loading $fU from database using IP
sql_pvquery("elxpbx", "SELECT name FROM sip WHERE host = '$si'
AND sippasswd IS NULL", "$var(tempfU)");
# source IP allowed
return;
}
The problem is that when host= somefqdn.com the above will fail since
$si will always be an IP address as far as I can tell. More often than
not host= is a fqdn and requiring it to always be an IP address is not
an option. Converting it to IP before storing it in the DB is also not
an option because it needs to be able to work of the IP address changes.
So how can the above be done to accomodate the possibility that host=
somefqdn.com or an IP address. Preferably in such a way that it can
scale to hundreds/thousands of rows in the database without slowing
things down or crashing.
