Your phone monitors the duration of all calls through a local call timer. You
can view the call timer for the active call and for calls on hold.
In the figure below, the active call to Jack Jones has lasted for 21 minutes, 19
seconds. The calls to James and Jacklyn have lasted for 41 minutes, 21 seconds
and 41 minutes, 39 seconds respectively.

directories, and speed dial lists to display and dial numbers for you. You can also
redial numbers. For more information, see

Contacts on page 2-46 , Placing Calls Using Speed Dial on page 3-10 , and
