Patent US 5,651,053

A Call Screening service assists a subscriber to the service to screen incoming calls. In response to an incoming call, the subscriber is given a special ring. When the subscriber answers the call, a caller who has placed the call is identified to the subscriber without connecting the subscriber to the caller. This is accomplished by prompting the caller to speak through the phone into a recording machine. The recording of the caller's name is played to the subscriber, who then has the option, still without being connected to the caller, to accept the call, refuse the call, or enable the caller to leave a recorded message for later access by the subscriber. This function is accomplished by pressing a key on a telephone keypad or by uttering a command. A special caller list can be created enabling preferred callers to reach the subscriber without being screened, and a refusal list can be generated for automatically blocking calls from disfavored callers. A new and effective way of terminating calls in mid-conversation is also provided.
