Caller ID overview
How caller ID works
If you subscribe to caller ID service provided by
your telephone service provider, information about
each caller is displayed between the first and
second ring.
The time and date of the call, along with the
caller’s name and telephone number, are included
on the screen if they were sent by the caller’s
telephone service provider. Due to regional service
differences, the caller ID information might not
be available for every incoming call. In addition,
the callers might intentionally block their names
and/or telephone numbers. Other messages might
appear on the screen. Refer to
Caller ID special
messages on page 36 for more information.
Caller ID information appears on the screen as
long as the telephone rings, for 30 seconds after
the caller hangs up, or after the call is answered at
another telephone on the same line.
NOTE: If you select COMBINED in REPEATED
CALLS (see Feature summary on page 16) and
a caller has called more than once, the
REP icon
appears with the caller ID entry.
