title: Twilio Client to Client call - reject/ignore
body: <p>My <code>Twilio</code> Client js application allows agents to call each other within the browser. The call is working and after accepting the call both agents can then end the call via <code>Twilio.Device.disconnectAll()</code>. This fires the disconnect callback on both sides allowing updates to the UI.</p>
  
  <p>Cancelling the call from the caller side correctly raises the cancelled event on the dialled side again allowing UI updates.</p>
  
  <p>However I am having trouble updating the UI on the caller side if the dialled agent does not wish to take the call. I have tried the <code>Device.disconnectAll()</code> and the <code>Connection.reject()</code>, <code>ignore()</code> and <code>disconnect()</code> methods but it raises no events/callback on either side and the call continues to ring.</p>
  
  <p>I presume I am missing a step somewhere. Any advice would be much appreciated.   </p>
