Hi nkans, First thank you so musch for your help. I change your script a litter because I want forward all call that not call 6169xxxx to gateway and checking other call. If other call not in location, return 404 error. And I can't use "else" after "if" because it make script fail. That my script(only changed these codes):

if(uri=~"^sip:6169[0-9]*@[0-9|.]*") { if(!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; # I can't use else here forward(172.16.255.1,6050); break;

Best regards, Wangji

let me know whether it works. here is the corrected script.

# ----------- global configuration parameters ------------------------

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

            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

    # with proper names and addresses in it)

                    break;

    };

                            forward(172.16.255.1,6050);

            };

    # forward to current uri now; use stateful forwarding; that
    # works reliably even if we forward from TCP to UDP
    if (!t_relay()) {
            sl_reply_error();

}
