Hi, I am doing a similar thing but not yet succeed. As far as I know you could try originate with eavesdrop, or three_way app though not yet working for me. For your last question, I don't know from where you would call eavesdrop app: from dialplan or ESL app or some scripts. I don't know how to check the status such as ready, answered or busy etc of the originated session from a Java ESL app which I am using but I notice some one did that kind of checking by some scripts (JS or Lua ?) ( I couldn't find it for the moment) You can do a search and I am sure you will find it.

Taking a look at the eavesdrop application, I think this will do what I want. Quick question: instead of having calling prefixes to enable the app, could I call the eavesdrop application after getting busy/congestion and allow barge-in?
