  • Validation query based on a supervisory signal
    Patent number: 6430274
    Abstract: A telephone system and method is provided for delaying authorization validation queries until after a called party accepts a telephone call. Queries are avoided not only in cases where the called phone line is busy or not answering, but also in cases where the called party declines to accept the charges. Because authorization validation queries typically take less than half a second, parties are not significantly affected by the delay.
