    <tt>Hi Eric,<br>
      <br>
      By traffic (coming back), you understand RTP or SIP traffic ?<br>
      <br>
      Could you post the INVITE message getting out of your server ? I
      suspect the INVITE has in SDP a private IP that is not reachable
      for the end device (where the call is sent).<br>
      <br>
      Regards,<br>

        <p>Yes, I see Request INVITE going to the device I am calling. I

        Not the OpenSIPs logs I'm looking for, but the actual SIP packet

                  <b>To:</b> Eric Freeman; OpenSIPS users mailling list<br>

              <div><tt>He Eric,<br>
                  <br>
                  In the script (generated by menuconfig), you have an
                  IF block with :<br>
                      append_hf("P-hint: outbound\r\n");<br>
                  <br>
                  That block is executed if one of your users is dialing
                  an external SIP domain. So, that is the place where
                  the calls will break out to public internet.
                  <br>
                  <br>
                  As your OpenSIPS has a private IP (not routable in
                  internet), you need to configure it to advertise the
                  public IP of your NAT via the set_advertise_address()
                  - see:<br>
                      <a moz-do-not-send="true"
                    class="moz-txt-link-freetext"
href="http://www.opensips.org/Documentation/Script-CoreFunctions-2-2#toc46">http://www.opensips.org/Documentation/Script-CoreFunctions-2-2#toc46</a><br>
                  <br>
                  Put there the public IP of your NAT. Also, be sure you
                  create in your router (running the NAT) a port
                  forwarding from the public IP port 5060 UDP to the
                  private IP of your OpenSIPS port 5060 UDP.<br>
                  <br>
