How caller ID works
If you subscribe to caller ID service provided by your
telephone service provider, information about each caller
will start to be displayed between the first and second
ring.
The time and date of the call, the caller’s name and
telephone number are included on the screen if sent
by the caller’s telephone service provider. The incoming
line of the call also appears on screen (L2 in the above
example). If two calls come in at the same time, the
screen displays information about both calls:
In certain circumstances, there may be up to a 6-second
delay before the screen displays both caller's information.
Other messages may appear on screen. See
Display
screen messages on page 57 for more information.
Caller ID information will remain on the screen for about
30 seconds after the telephone stops ringing or until the
call is answered.
If you subscribe to caller ID service, this telephone
automatically resets the time and date each time new call
information is received. You can set the time and date
yourself if desired. (See
Set the time and date on page
22.)
NOTES:
Caller ID features work only if both you and the caller are in areas
offering caller ID service, and if both telephone companies use
compatible equipment.
If caller ID information is received while you are programming the
memory, the call information will be stored in call history without
appearing on screen. 1.
