* 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.
