Hi this is a little example from my perl code that do that:

array random_be contains randomized IP addresses of next hops.
there also hash:
my %hunt_error=(
        NO_USER_RESPONSE => 1,
        NETWORK_OUT_OF_ORDER => 1,
        DESTINATION_OUT_OF_ORDER => 1,
        SYSTEM_SHUTDOWN => 1,
);

If error is defined in this array we hunt else drop call. I assume that these errors are internally generated from this FS instance or comes first remote hop. So I need to hunt over next hop. But if error comes from last server I drop call and do not hunt over rest of my SIP servers.

for (my $i=0;$i <= scalar(@random_be) ; $i++) {
        my $dst_gw = shift(@random_be);
        print "GW:[$dst_gw]\n";
        $bridge = "sofia/internal_out/$called\@$dst_gw";
        $session->execute('bridge',"$bridge");
        $berror = $session->getVariable("originate_disposition");
        if (defined($berror)){
                fprint("\tBridge Error - Check continue or not\n");
                if (!defined($hunt_error{$berror})){
                        fprint("\t HANGUP - ERROR NOT DEFINED");
                        $session->execute('export','continue_on_fail=false');
                        $session->hangup();
                        return (1);
                }
        } else { last; } ;  ### NO originate_disposition so successful bridge
}

Suppose this will help. Not in Lua but idea is the same.

Cheers

And what about variables are not available before the call setup (like
uuid), only during the call progress or after the hangup???
I would need to access the originate_disposition variable...

any other hint???
