 * \class CMobilePhoneBookStore MPHBOOK.H "MMTSY/MULTIMODE/MPHBOOK.H"
 * \brief The CMobilePhoneBookStore class is one of the Multi mode TSY's sub-session extensions responsible
 * for handling Client-side calls from the Multi mode API.
 *
 * CMobilePhoneBookStore inherits from the CSubSessionExtBase class defined in et_phone.h (which in turn
 * inherits from various mixin classes (MSubSessionExtBaseTSY, MTelObjectTSY). This sub-session
 * extension class implements all the pure virtuals (functions) from the inherited classes
 * including ExtFunc(), CancelService(), ReqModeL() etc.
