      thank you, that did the trick! <br>
      I added a pre_aswer, a playback and finally a ring_ready in order

            <div bgcolor="#FFFFFF" text="#000000"> Hello,<br>
              <br>
              I have the following scenario<br>
              <ul>
                <li>Freeswitch is behind NAT with external profile with
                  ext_sip_ip and ext_rtp_ip</li>
                <li>Echo from an external SIP provider test inbound
                  works with audio</li>
                <li>Calling outbound to the same external SIP provider
                  works with audio</li>
                <li><b>Receiving a call from the external SIP provider
                    and bridging it to another number at the same
                    external SIP provider does not have audio</b></li>
                <li>Receiving a call from the external SIP provider and
                  bridging it to a local Patton PRI works with audio</li>
              </ul>
              <p>I also set up another (modified NAT) profile<br>
              </p>
              <ul>
                <li>like external profile - but with a different
                  ext_rtp_ip </li>
                <li>calling outbound to via NAT profile to another SIP
                  provider works with audio</li>
                <li><b>Receiving a call from the external SIP provider
                    (external profile) and bridging it to another
                    number&nbsp;</b><b>at the another external SIP provider </b><b><b>(nat</b><b><b>
                        profile)</b></b> does not have audio</b></li>
                <li>Tcpdump btw. does not show an attempt of Freeswitch
                  to issue any outbound RTP packet. I can see only SIP
                  messages towards the outbound SIP provider<b><br>
                  </b></li>
              </ul>
              <p>So I think, there is a problem with briding a natted
                external call&nbsp; to another natted external call, both
                with ext-rtp-ip. It tried this on an older Freeswitch (1
                year old) and with a more recent Freeswitch (1 month
                old), both behave the same. Same scenario with a
                non-natted Freeswitch works fine. <br>
                Btw. Freeswitch logs do show <br>
                &nbsp;&nbsp;&nbsp; RTCPpacket not written<br>
                right after bridginbg the call.<br>
              </p>
              <p>Question: Does anybody have a clue, what could cause
                the problem? Maybe there is any parameter in the
                profiles, that may help?<span class="HOEnZb"><font
