      <br>
      The paragraph you refer to is this one :<br>
    </font><br>
    <pre class="newpage">      o  After having sent or received an answer to the first offer, the
         UAC MAY generate subsequent offers in requests based on rules
         specified for that method, but only if it has received answers
         to any previous offers, and has not sent any offers to which it
         hasn't gotten an answer.</pre>
    <font face="monospace"><br>
      So the 200 must contain the same SDP as the 180 because there is
      no SDP replied back between the 180 and 200 ?<br>
      <br>
      Regards,<br>
