All calls made to or from your telephone are added to the Call Log
(unless your Call Log Active? Option is set to No).
The log displays the caller's name, caller's phone number, time and date of the
call, type of call (incoming, outgoing and unanswered), and call length
(expressed in hours/minutes/seconds) as available. 
If the phone loses power
or is reset, all Call Log entries will be lost, and are only available if your
Call Log had been previously archived and
restored.
