NEW: small limitation due to Google policy changes: Ending a call: The FMC app can no longer directly end native (cellular) calls. As a work-around the FMC client now sends DTMF **49 to let the server hang up the call. This only if it has a data connection and is registered. If not then the user has to end the call manually by pressing the red button in the native call screen.
