VOICE RECOGNIZING TELEPHONE CALL DENIAL SYSTEM ABSTRACT OF THE DISCLOSURE A call denial apparatus for denying a subscriber's access to a trunk. A voice recognizer is connected to the trunk, and receives a password spoken by the subscriber. The apparatus then receives digits dialed by the subscriber over the subscriber's line and carried by the trunk, matching them with one or a series of digits stored in a memory. In the event the password or subscriber's voice matches a predetermined password or voice, the digits which are dialed are passed over the trunk. However in the event that the password or voice does not match the predetermined password or voice, and in the event a predetermined one or group of digits are dialed which match a prohibited digit or group of digits stored in the memory, the trunk is split, and the subscriber is restricted from further access to the trunk. Thus only predetermined subscribers have full access to the trunk, and other subscribers have access only for limited services, or for no services. The voice recognition design allows different subscribers to have different classes of service, and for the first time does not tie trunk restriction to a subscriber's line, but to an actual subscriber.
