Hmm.. I'm having a hard time getting it to work.. Here is the configuration
I've got on my ser box.

No...All you need to do is to compile it and the run it.

 Do I need to do anything special with rtpproxy?

 Take a loot at the nathelper_rtp.cfg file under the modules/nathelper
 directory.   It contains the basics of what you need.

 The funcionality is basically determined by these lines:

         if (method=="INVITE") {
                 record_route();
                 if (isflagset(1)) { # ATA ?
                         force_rtp_proxy();
                 };
                 /* set up reply processing */
                 t_on_reply("1");
         };
 .
 .
 .
 onreply_route[1] {
         if (status=~"1[0-9][0-9]" && search("Server: Cisco
ATA.*"))
                 fix_nated_contact();
                 force_rtp_proxy();
 }

  Hmmm.. You wouldn't by chance have a
"scrubbed" version of your
 configuration file I could look at would you? It would be most helpful.

 Thanks for everything,
