How caller ID works

L4
If you subscribe to caller ID service provided by
your local telephone company, information about
each caller is displayed between the first and
second ring.
Time of call
Caller's
name
Entry
number
The time and date of the call and the caller's
name and phone number are included in the
display if they were sent by the caller's telephone
company. The incoming line number of the call
also appears (L4 in the above example). Other
messages might appear on the screen. See
Display screen messages on page 52 for more
information.
Caller ID information appears on the screen
as long as the phone rings, or until the caller
hangs up, or until the call is answered at another
extension, or until the extension that answered
the call hangs up.
If you subscribe to caller ID service, this phone
automatically resets the time and date each time
new call information is received. You can set
the time and date yourself (see Time/date in
Appendix B of this document).
