[OpenSIPS-Users] issue with trusted addresses listed with grp=0

[Andrew Pogrebennyk]

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:

> Jul  8 16:22:31 dev01 /usr/local/sbin/opensips[25047]: DBG:permissions:get_source_group: Found <1>
> Jul  8 16:22:31 dev01 /usr/local/sbin/opensips[25047]: 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?
