  • Patent number: 7133508
    Abstract: A subscriber's line is associated with a prepaid long distance account. When the subscriber attempts a long distance call, it is determined from the dialed digits whether the attempted call is a long distance call. If a long distance call is attempted, the subscriber's prepaid account is checked to determine whether it has any remaining credits. If no credits are remaining, the subscriber is so informed, and the call is disconnected. If the subscriber has credits remaining, the call is connected as long as credits are remaining in the prepaid account.

  • Patent number: 6931106
    Abstract: Systems and methods for using a voice-messaging system to place local and long distance telephone calls. In the invention, a voice-messaging system receives a toll-free call placed by a user and verifies that the user is a valid user of the voice-messaging system by accepting a pass code. The voice-messaging system then accepts the user's request to place a telephone call and the number to be called. Finally, the system places a call to the third party and connects the telephone call to the third-party telephone line if the third-party telephone line is available.
