* Description: 
*       Class that does processing for Phone Engine messages that are common
*       for all GSM states. Most of the GSM states are intressed of these 
*       messages but due to the class architecture they don't have any single
*       state class to be put into. This class exists to minimize duplicate
*       code so that not every GSM class need to implement these same handlings
*       for the same messages.
