//	This header file makes it clearer to the TSY developer which functions are to be implemented
//	in the TSY and which are not. However these classes are not to be derived from in the TSY
//	but are inherited by base classes in the server. The TSY should derive from CPhoneBase,
//	CLineBase, CCallBase, CFaxBase, CPhoneFactoryBase and for extensions CSubSessionExtBase.
