[Serusers] Configuring the SER proxy with RTPproxy

[Ehsan Karimi]

Dear All


i have a network , and all of nodes have valid ip addresses, i have
the ser 0.8.12 (i386/linux) with valid ip :


  My clients  ------------->  SER box (sip proxy) ------------->
carrier (Cisco Box )
  valid ip                           valid ip                         
           valid ip
  Windows messenger         version: 0.8.12                       IOS :12.2.4

The current config of my ser proxy is : 


fifo="/tmp/ser_fifo"
alias=panaisp.net

        if (!mf_process_maxfwd_header("10")) {
                log("LOG: Too many hops\n");
                sl_send_reply("483","Too Many Hops");

        setflag(1);
        setflag(2);
        acc_rad_request("");


        if (method=="INVITE") {
             record_route();
             if (!radius_www_authorize("panaisp.net")) {
                  www_challenge("panaisp.net", "0");
                  break;
             };
        } 


        if (uri==myself) {

                if (method=="REGISTER") {

                       if (!radius_www_authorize("panaisp.net")) {
                               www_challenge("panaisp.net", "0");
                               break;
                       };

                        save("location");
                        break;
                };

                if (lookup("location")) {
                        forward(uri:host, uri:port);
                        break;
                };
        };




if (uri=~"^sip:[0-9]*@") {

  if (uri=~"^sip:00" ) {
    strip(2);
  }

  if (uri=~"^sip:[2-9]") {
    prefix("82135011");
  } else {
    prefix("82135");
  }

  rewritehostport("63.243.143.8:5060");

};

forward(uri:host, uri:port);

}


I want to force the RTP traffic of my clients pass through the ser server .
Then i deside to use the RTP proxy + nathelper .

Please advise me that what change i must do in my current ser config  ???

Best Regards
