Hello,
I am using the address table to keep the trusted IPs like this:
# check trusted IPs
$var(group) = get_source_group();
if ($var(group) == 32) { # use grp=32 as trusted indication
xlog("L_INFO", "Call from trusted peer - M=$rm RURI=$ru F=$fu T=$tu
IP=$si ID=$ci\n");
# do something stupid
} else {
if(!proxy_authorize("", "subscriber")) {
proxy_challenge("", "0");
exit;
}
# process the call
}
Something strange happens when the INVITE source IP comes from the
address listed with grp=0 - the call seems to get stuck and never gets
to digest challenge:

It looks as if something was wrong with script variables operation
because with any grp!=0 there is a comparison operation after the
"Found" line:

> DBG:core:comp_scriptvar: int 20 : 1 / 32
However I can give up an idea that I am doing something stupid, else
with 0 being default value much more people would have noticed this
problem before. Any ideas?
