Caller ID Features
Understanding the Caller ID service
Caller ID allows the caller’s phone number to be shown on the display
before you answer the call. In order to use this feature, you must first
subscribe to Caller ID service. The name of this service may vary
depending on your telephone company.
To use this feature, be sure to enter the area code (see page 17).
When you receive a call
The phone number appears on the display as shown in the following
example.
If your Caller ID service includes the caller name service or if the
phone number stored in the Phone Directory matches with the Caller
ID data phone number, the caller’s name also appears on the display
(up to 15 letters).
The caller’s name will appear by the name stored in the Phone
Directory if you receive a call from a phone number which is stored in
the Phone Directory.
When you answer the call, the Caller ID display changes to the
“TALK” display.
Notes
• The caller’s phone number and/or name will not appear in the following
cases:
—“UNKNOWN NUMBER/NAME/CALLER” (out of area) : when the call is
made through a telephone company which does not offer Caller ID service
(including international calls).
—“BLOCKED NUMBER/NAME/CALL” (private) : when the call is
“blocked”. For privacy reasons, many states allow callers the option to
prevent his or her telephone data from being displayed on the other
party’s Caller ID display.
• If the call is from an office which uses multiple lines, the displayed phone
number may not match the number you use to call the extension.
About the memory match function
The name stored in the Phone Directory will appear on the display and
the ringer sound will change to a higher tone from the second ring if
you receive a call from a phone number which is stored in the Phone
Directory on the cordless handset (see page 39).
Note
The memory match function does not work with “UNKNOWN NUMBER/
NAME/CALLER” or “BLOCKED NUMBER/NAME/CALL” calls; and it may
not work with calls made from an office which uses multiple lines because the
number does not always match the one you stored in this phone.
