* Description: 
* 		Class that does processing for Phone Engine messages that are common
*		for all VoIP 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 VoIP class need to implement these same handlings
*		for the same messages.
