[Serusers] Calls between UA´s behind same NAT using nathelper/rtpproxy

[Rafael J. Risco G.V.]

Hello
I am using avpops module to detect if source IP is the same as
destination IP and then comunicate both UAS directly but it doesn't
work, please see my configs:

----.
                if (!lookup("location")) {
                        log(1,"unable to locate user \n");
                        # handle user which was not found
                        route(4);
                        break;
                };

                ### Test if UAS are in the same NAT:
                # get the host part of the final uri (IP part) and
store it in AVP ID 13

                avp_write("$ruri/domain", "i:13");
                if (avp_check("i:13","eq/$src_ip/i")) {
                        log(1, "source IP is the same as destination IP\n");
                        route(3);
                        break;
                };
                avp_delete("i:13/g");
.

# -------------- Same NAT Call Routing (no force rtpproxy) ----

route[3]{
        log(1," route[3]: UAs are in the same nat, NO force_rtp_proxy ");
        if(!t_relay()){
                sl_reply_error();
        };
}
.
.
.
any idea?

thanks
