ABSTRACT:
A telephone system and method is provided for delaying authorization validation queries until a dialed phone is answered. This way, authorization validation queries are avoided in cases where a requested phone line is busy or not answered. In a collect call scheme the system may even delay queries until a party agrees to accept the collect call billing charges. This way, query charges are avoided not only for busy signals and no-answers, but also in the event that the requested party declines to accept the charges. Because authorization validation queries typically take less than one half of a second, parties are not significantly affected by the delay.
