No expert on these units so the following may or may not be applicable as a solution to your problem.   Does your unit have a backup battery (saves settings in case power goes out).  If it does, it may need replacing.  The user's manual states the the "answerer must be switched on".  If the battery does need replacing it could also mean that the settings for the answerer have been toggled off.  Just a thought.
