Abstract
A verifying non-user outcall unit within a voice messaging system attempts to deliver a subscriber's message to a non-subscriber. During the delivery attempt, the verifying non-user outcall unit directs the recording of a signal returned after dialing a recipient's telephone number. The verifying non-user outcall unit analyzes the signal returned, and determines whether the delivery attempt is successful. If the delivery attempt is unsuccessful, the verifying non-user outcall unit stores the recorded signal and a nondelivery notification in the originating subscriber's mailbox. If the delivery attempt is successful, the verifying non-user outcall unit stores a voice signal recorded after the recipient telephone is answered and a delivery notification in the originating subscriber's mailbox.
