title: asterisk confbridge and answering machine detection
body: <p>I have an outbound conferencing system using asterisk. I call all the participants and connect them to music on hold. when the last participant answers I start the ConfBridge application.</p>
  
  <p>I want to know if the call to the last participant was answered by a human or voicemail, and I thought about using the AMD application. Is it possible to run this application after starting the ConfBridge app?</p>
