[Freeswitch-users] how to access session variables after hangup???

[ivdreg ivdreg]

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
