+  <p>Note that a unique zrtp-hash is needed for each media stream, since the hash for each stream is computed from a different ZRTP Hello message (e.g., if a session includes both audio and video then the value of the &lt;zrtp-hash/&gt; element included in the &lt;description/&gt; element for the audio stream will be different from the value for the video stream).</p>
