#region About DirectPlay Voice
// Since the DirectPlay Voice API defines server and client interfaces,
// but not a peer interface, one of the peers must act as the server
// for voice communication; the logical choice is the session host, so
// for this sample, the session host creates a server object in addition
// to a client object. Note that in order to send and receive voice
// messages you must have a connected voice client object, even if you
// are acting as the voice server.
