    Hello,<br>
    <br>
    the reply code indicates that the media type is not supported, thus
    there has been no gatewaying between webrtc and classic rtp. Just
    replacing rtpproxy with rtpengine is not enough, there are different
    parameters that have to be provided.<br>
    <br>
    Searching on web, I see that Carlos has published a config for it,
    see:<br>

          <div>Hi, <br>
            <br>
          </div>
          I have successfully setup rtpproxy-ng kamailio module and
          mediaproxy-ng package on my ubuntu box. As suggested here:<br>
          <a moz-do-not-send="true"

        </div>
        <div><br>
        </div>
        <div>I have kept rtpproxy-ng's configuration same as the
          rtpproxy module, but still not able to connect the webrtc
          calls to classic sip phones (and vice-versa). Below is the sip
          message that is traced:<br>
