[OpenSER-Users] nathelper without rtpproxy

[Nhadie Ramos]

Hi Dan,
My pstn gateway is on public IP, my SIP server is also on public IP.
most clients are behind NAT, using DSL routers, STUNS are configured on 
the PAP2's

This is a part of the config, what can i change to not use rtpproxy, i 
read somewhere to use fix_nated_sdp("3"),
 i tried that but callers cannot hear the other side

        if (nat_uac_test("19")) {
                if (method=="REGISTER" || !search("^Record-Route:")) {
                        log("LOG: Someone trying to register from 
private IP, rewriting\n");
                        fix_nated_contact();
                        if (method == "INVITE") {
                                fix_nated_sdp("1");
                        };
                        force_rport();
                        setflag(6);
                };
        };

if ((uri=~"^(sip:)?00*@([a-z]+\.)?mydomain\.com")
                        || (uri=~"^(sip:)?00*@202\.202\.202\.202")) {
                                if (isflagset(8)) {xlog("L_INFO", "Calls 
to PSTN\n");};
                                if (isflagset(6)) {route(1);};
                                strip(2);
                                if (isflagset(8)) {xlog("L_INFO", 
"Retail Server\n");};
                                prefix("12345#");
                                rewritehostport("203.203.203.203:5060");
                                consume_credentials();
                                t_relay_to_udp("203.203.203.203", "5060");
                                break;
}

route[1] {
        xlog("L_INFO", "User-Agent behind NAT\n");
        force_rtp_proxy();
        if (method=="INVITE") {
                t_on_reply("1");
        };
        append_hf("P-Behind-NAT: Yes\r\n");
        break;
}

onreply_route[1] {
        if (status =~ "(180)|(183)|2[0-9][0-9]") {
                fix_nated_contact();
                if (!(search("^Content-Length:\ 0"))) {
                        force_rtp_proxy();
                };
        };
}
