A calling party announcement apparatus that provides the identity of the caller
in synthesized human speech. The invention captures the Incoming Caller Line Identification
(ICLID) signal sent by the telephone company. The invention announces the calling
party's identity to the called party through a built-in speaker and over the telephone
receiver. The called party can elect to accept or reject the call before the telephone
company central office has connected the two parties together. The invention makes
it possible to screen incoming telephone calls without the aid of a special Caller
ID telephone set or auxiliary Caller ID display terminal. The invention is installed
in the customer premises, such as a residence or office, between the telephone
line demarcation point and the telephone sets. The invention is compatible with
any standard telephone set and subscriber trunks provisioned with the Caller ID
enhanced customer feature. One of the most important features of the invention
is its ability to deliver a vocalized announcement of the caller's identity over
a standard telephone set's receiver without the call having actually been declared
answered by the telephone company, and without the caller having been cut through.
The call is not considered "answered" nor is it billed by the telephone company
unless the called party or a telephone answering device, such as an answering machine,
accepts the call.
