title: Detecting an incoming call in Lync
body: <p>I'm trying to detect an incoming call in the Lync client . This is done by subscribing to ConversationManager.ConversationAdded event in the Lync client as described in <a href="https://stackoverflow.com/questions/7144519/integrating-lync-2010-with-an-external-program">this post</a></p>
  
  <p>However, by using this method I'm not able to detect incoming calls if a conversation window with the caller is already open before the caller is calling. 
  For instance if I'm chatting with a friend and therefore have a open conversation windows and this friend decides to call me, the ConversationAdded event is not triggered.</p>
  
  <p>How would I detect incoming calls when I already have an active conversation with the caller?</p>
  
  <p>Thanks, 
  Nicklas </p>
