* 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.
