[Freeswitch-users] barge-in on active call

Hi, I am interested in having barge-in capabilities for active calls, essentially to have the ability to join a call that is in progress. 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? Kind regards, -- --truman
