I encountered such a problem in the process of doing the project：
Send the event in judging the current state of the MediaFlowState, if the state is equal to MediaFlowState.Active, began to send a message,
I'm in our test server, as long as the implementation of the event, it will automatically trigger for the MediaFlowState.Active state,
But when i run it in another server machine, Lync can manually clickpopup message window, or for a period of time (when the Lync messageform will automatically minimized to the taskbar), the state will be updated for MediaFlowState.Active, the message to send.
Why is it so? I want to make it automatically trigger
