New subject: Re [Serusers] RTPProxy only fails for Public to Private communication

7 Apr 2005

Hi Greger (Sorry forgot to copy the serusers mailing list the 1st time),

I made that change and my on_reply_route now looks like this:

 onreply_route[1] {

   if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") {
        fix_nated_contact();
        if (!search("^Content-Length:\ 0")) {
                force_rtp_proxy();
        };
     } else if (nat_uac_test("1")) {
           fix_nated_contact();
};
}

Unfortunately when I restarted rtpproxy, SER and reregistered my phones, I still had the
same message dump.

I assume this is where you get an error message. You haven't called
fix_nated_contact() for this message, and in fact I believe there may be an error in the
ONsip.org example where a line has been lost.

192. onreply_route[1] {

193.

194. if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") {

195. if (!search("^Content-Length:\ 0")) {

196. force_rtp_proxy();

197. };

198. } else if (nat_uac_test("1")) {

199. fix_nated_contact();

200. };

201. }

fix_nated_contact() should go in between line 194 and 195.  

Could you please confirm that this works?  I will look at the config file.

  Just as an extra : I have a sniff of the message for
when a public
 client (2092)rings a private client (2093)included at the bottom of
 this email. I cant see anything wrong with them but maybe it will
 shed more light on the matter.

 I changed the line modparam("nathelper", "rtpproxy_sock",
 "/var/run/rtpproxy.sock") to modparam("nathelper",
"rtpproxy_sock",
 "udp:localhost:22222") and started the rtpproxy as ./rtpproxy -s udp
 from the relevant directory and this resulted in a series of
 "rtpp_command: no response from rtpproxy" and rtpproxy temporarily
 disabled" errors. If I return to the original modparam and start it
 as ./rtpproxy then it works but like I said when the private client
 rings the public client, I get "ERROR: send_rtpp_command: cant read
 reply from a RTP Proxy".        

 Any further ideas? Has anyone on the mailing list experienced this? I
 am using the script given in the onsip getting started doc for 0.9.0.
 but am using ser 0.8.14.
