RECEIVING AND STORING
CALLS
Caller ID is a service provided by your
telephone company. When you subscribe
to this service, the telephone company
sends the caller's telephone number (and
name, if available) and the call's date and
time between the first and second rings.
The CID receives and displays this
information for each call and updates the
display with the current date and time.
