[Serusers] rtpproxy/nathelper configuration issues. i think.

[Andres]

Eric,

I think you should just try out the example RTP config in the nathelper 
directory.  It is this one:

# main routing logic

route{

        # compulsory processing of Route header fields and adding RR
        loose_route();

        # ATA's are symmetric but don't advertise it -- force use of rport
        if (search("User-Agent: Cisco ATA.*")) {
                setflag(1); # remember this is ATA
                force_rport();
                fix_nated_contact();
        };

        /* registration (uses rewritten contacts) */
        if (method=="REGISTER") {
                save("location");
                break;
        };

        if (method=="INVITE") {
                record_route();
                if (isflagset(1)) { # ATA ?
                        force_rtp_proxy();
                };
                /* set up reply processing */
                t_on_reply("1");
        };

        if (method == "INVITE" || method == "CANCEL") {
                if (!lookup("location")) {
                        sl_send_reply("404", "Not Found");
                        break;
                };
        };

        /* set up reply processing and forward statefuly */
        t_relay();
}

# all incoming replies for t_onrepli-ed transactions enter here
onreply_route[1] {
        if (status=~"2[0-9][0-9]" && search("Server: Cisco ATA.*"))
                fix_nated_contact();
                force_rtp_proxy();
}
