Caller ID operation
Caller ID overview
How caller ID history (call log) works
The telephone stores caller ID information about the last 50 incoming calls
in the telephone base. Entries are stored in reverse chronological order. The
telephone deletes the oldest entry when the log is full to make room for new
calls. This information is common to all handsets, so changes made in any
handset are reflected in all other handsets. If you answer a call before the
information appears on the screen, it does not show in the caller ID history.
Review the caller ID history to find out who called, to easily return the call, or
to copy the caller's name and number into your directory.
XX NEW CALL(S) appears if there are
new caller ID history entries (including
missed and unreviewed calls). CALL LOG
EMPTY appears if there are no records in
the caller ID history.
NOTES:
• Only one handset can review the caller ID history at a time. If another handset attempts to
enter the caller ID history, it shows NOT AVAILABLE AT THIS TIME.
• Each entry may have up to 24 digits for the telephone number and 15 characters for the
name. If the telephone number has more than 15 digits, only the last 15 digits appear.
• The caller ID information might not be available for every incoming call. The callers might
intentionally block their names and/or telephone numbers.
Memory match
If the incoming telephone number is an exact match with a telephone
number in your directory, the name that appears on the screen matches the
corresponding name in your directory.
For example, if Christine Smith calls, her name appears as Chris if this is how
you entered into your directory.
NOTE: The number shown by your caller ID is in the format sent by the telephone service
provider. The telephone service provider usually delivers ten-digit telephone numbers (area code
plus telephone number). If the telephone number of the caller does not exactly match a number
in your directory, the name appears as it is delivered by the telephone service provider. For
example, if the telephone service provider includes the area code and the directory number does
not, the name appears as delivered by the telephone service provider.
