Caller ID

Caller ID history

How caller ID history (call log) works

The telephone stores caller ID information about the last 50 incoming calls in the telephone base. Each entry may have up to 24 digits for the telephone number and 15 characters for the name. Entries are stored in reverse chronological order. The telephone deletes the oldest entry when the log is full to make room for new calls. If you answer a call before the information appears on the screen, it does not show in the caller ID history.

NOTE: The caller ID information might not be available for every incoming call. The callers might intentionally block their names and/or telephone numbers (see Reasons for missing caller ID information on page 33).

Memory match

If the incoming telephone number matches the last seven digits of 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 it into your directory.

Chris

888-722-7702

11:30PM 11/20

NOTE: The number shown by your caller ID is in the format sent by the telephone service provider. The telephone service provider usually delivers 10-digit telephone numbers (area code plus telephone number). If the telephone number of the caller does not 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.
