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 call is missed and unreviewed.

incoming caller ID

 

The time and date of the call, 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 34 for more information.

Caller ID information appears on the screen as long as the telephone rings, for 15 seconds after the caller hangs up, or after the call is answered at another telephone on the same line.

If you subscribe to caller ID service, this telephone automatically resets the time and date each time new call information is received. You can also set the time and date yourself (see Set date and time on page 17).

NOTE: If you select COMBINED in REPEATED CALLS (see Feature summary on page 15) and a caller has called more than once, the REP icon appears with the caller ID entry.
