    <tt>Hi Nabeel,<br>
      <br>
      You mentioned getting some "failed to load module" errors - maybe
      your script id pointing to a different path rather than where your
      opensips is installed.<br>
      <br>
      The "unknown commnad" errors are side effects of modules not being
      loaded.<br>
      <br>
      Regards,<br>

                          <p>Dear OpenSIPS-users,</p>
                          <p><br>
                          </p>
                          <p>I'm studying about NAT traversal with
                            OpenSIPS, since last week. I also have found
                            the documentation about the software
                            MediaProxy (in <a moz-do-not-send="true"

                          <p><br>
                          </p>
                          <p>As long as I'm still getting 'kind of first
                            steps' knowledge base about NAT traversal,
                            I'm not interested, at least for a while,
                            in MediaProxy software functionalities.</p>
                          <p>By the way, as a first contact with the NAT
                            traversal mechanism, I just would like
                            to let the INVITE from a caller reaches
                            the callee, with caller behind a NAT. For
                            this purpose I have 2 questions:</p>
                          <p><br>
                          </p>
                          <p>a) Am I free of using a kind of mediaproxy
                            software, whether I want to build a
                            prototype schema that will just creates and
                            sends an simple INVITE, from caller behind a
                            NAT, to a callee? That is, if I want just to
                            run a simple test of NAT traversal, I don't
                            have to worry about mediaproxies, have I?</p>
                          <p><br>
                          </p>
                          <p>b) How could be an example of
                            a simplest script code for that, considering
                            that there is only one proxy for all peers
                            and all of it is registered in such
                            proxy using the same domain?</p>
                          <p><br>

                          <p>Any hint will be very helpful!!</p>
