title: Recognize call answer event in Asterisk AMI
body: <p>Which event shall I use to recognize the end of conversation with employee?</p>
  
  <p>There are some events: Unlink, Hangup, Dial (Subevent: End)</p>
  
  <p>As I understood, Unlink event (without following Bridge event) suits best, but it can be fired a lot of times during conversation.
  Dial (Subevent: End) and Hangup doesnt fire when call is transferred to another employee.</p>
