ABSTRACT:
A toll call service center of the present invention is accessible by subscribers to a toll call service. One or more of the subscribers of the service have their own set of identifiers uniquely associated with a plurality of called stations desired to be accessed by the subscriber. The center comprises a voice command system having a storage for storing representations of the identifiers at storage locations uniquely identified with the subscriber. The command system also includes an announcing circuit and a processor operative under the control of a program stored therein. The processor is responsive to reception of an incoming call from a subscriber for controlling the announcing circuit to request the subscriber to speak an identifier associated with one of the plurality of called stations. A voice recognizer is responsive to receipt of the identifier for determining whether the identifier is valid. If the identifier is recognized as belonging to the subscriber, the processor controls an outdialer to dial the telephone number of the called station associated with the identifier.
