   ========   ========    ==========================
   2005-06-23 w16355      CR - LIBgg36361
              Need additional logging capabilities.

   2004-09-21 w19069      CR - LIBff18839
                          Add accessory mute/unmute functionality for Atlas UL
              
   2004-02-26 w17860      LIBdd64152
                       OT: Interrupted audio when call waiting advice is signalled
                       - Added logging for HAPI signals
