Since the Telcos had ANI, the decision was made to make it available to authorized parties such as 911 service and state security services.

Caller ID lets you know who’s calling even before you pick up the phone. This service allows you to see the date, time, and phone number (and sometimes name) of direct-dialed local and long-distance calls before you answer the telephone. Caller ID reveals this information in a display window on your phone or on a unit that attaches to your telephone. The memory in the display unit is programmed to store the number, as well as the date and time of the call. This way, if you’re not home or don’t want to answer the phone, the stored numbers will permit you to see who has called. However, if the calling party’s number is blocked, their number will not be displayed or stored by the Caller ID device.
