    <tt>Hi Riko,<br>
      <br>
      I understand, but my knowledge over rtpengine is not so good.
      Maybe you should ask over the rptengine project.<br>
      <br>
      Best regards,<br>

          <div>Hi Andrei,<br>
            <br>
          </div>
          <div>The opensips and rtpengine is interacting, for
            overwriting the SDP. We tested "JsSIP client with (opesips +
            rtpengine)" and it is working fine.<br>
            <br>
          </div>
          <div>Here, DTLS handshake is happening using rtpengine, and so
            SRTP is handling by rtpengine.<br>
            <br>
          </div>
          <div>But I don't want rtpengine to handle SRTP traffic. Only
            the "DTLS handshake" needs to be handled by RTPEngine and I
            just need the crypto method and the crypto keys from
            rtpengine to be sent to opensips.<br>
            Do you have any suggestion for fetching the crypto keys from
            rtpengine?<br>
          </div>
          <div><br>

          Thanks,<br>

                              There are no SDP answers created by
