An apparatus, system and method of providing auto-dimming and state transition signal functionality to a telephone system are provided. Generally, when the telephone system is in use, it will have an illuminated screen that may distract others. Because of this, when the telephone system is entering a state that does not require monitoring by the user, the illuminated screen may dim down to decrease the likelihood of distraction by others. However, since the user may want to know when the telephone system is no longer in that state, the telephone system may alert the user when it has transitioned out of that state.
