[Users] AVPOPS module problem

[Alexandre Passito]

Hi,

I'm trying to implement a "black list" with avpops module, but I got
some errors:

This is my cfg file:

#

# simple quick-start config script

# -------------------------  request routing logic -------------------

# main routing logic

route{

	# initial sanity checks -- messages with
	# max_forwards==0, or excessively long requests
	if (!mf_process_maxfwd_header("10")) {
		sl_send_reply("483","Too Many Hops");
		break;
	};
	if ( msg:len > max_len ) {
		sl_send_reply("513", "Message too big");
		break;
	};

	# we record-route all messages -- to make sure that
	# subsequent messages will go through our proxy; that's
	# particularly good if upstream and downstream entities
	# use different transport protocol
	record_route();	
	# loose-route processing
	if (loose_route()) {
		t_relay();
		break;
	};

	# if the request is for other domain use UsrLoc
	# (in case, it does not work, use the following command
	# with proper names and addresses in it)
	if (uri==myself) {

		if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication
#			if (!www_authorize("iptel.org", "subscriber")) {
#				www_challenge("iptel.org", "0");
#				break;
#			};

			save("location");
			break;
		};

		# native SIP destinations are handled using our USRLOC DB
		if (!lookup("location")) {
			sl_send_reply("404", "Not Found");
			break;
		};
	};
	# forward to current uri now; use stateful forwarding; that
	# works reliably even if we forward from TCP to UDP

#Black-list!!!

        if (method=="INVITE" || method=="MESSAGE")
        {
                if ( avp_db_load("$to/username", "s:not_allow/preferences")
			&& avp_check("s:not_allow", "eq/$from/gi") )
                {
			sl_send_reply("403", "Forbidden - You are blocked!");
                        break;
		}
	}

	if (!t_relay()) {
		sl_reply_error();
	};
	lookup("aliases");
}


My "preference" table looks like:

uuid(str) username(str) domain(str,null) attribute(str) value(str) type(int)
"":"peter":"200.129.163.139":"not_allow":"paul at 200.129.163.212":"0"

I'm using openser in to a local network. Its ip is 200.129.163.178.

peter address is 200.129.163.139

paul address is 200.129.163.212



The result is that both UA call each one, despite peter blocks paul.

Any help?
