// This class is to simulate a conference call. There are two Voice Engines, one
// for local channels and the other for remote channels. There is a simulated
// reflector, which exchanges RTCP with local channels. For simplicity, it
// also uses the Voice Engine for remote channels. One can add streams by
// calling AddStream(), which creates a remote sender channel and a local
// receive channel. The remote sender channel plays a file as microphone in a
// looped fashion. Received streams are mixed and played.
