Caller ID history
How caller ID works
If you subscribe to caller ID service provided by
your local telephone company, information about
each caller will be displayed between the first and
second ring.
Information about the last 50 incoming calls is
stored in the call history. You can review the call
history to find out who has called, and to return
the call without dialing, or copy the number or the
number and name into the speed dial or one-touch
locations.
If you answer a call before the information appears
on the screen, it will not be saved in the call history.
