发明名称 Apparatus and method for screening foreign incollect calls to domestic non-collect call telephone numbers to reduce fraud
摘要 An apparatus and method for automating the processing of foreign collect calls to U.S. telephone numbers. By automating the check of the U.S. telephone number against the pay telephone numbers and other non-billable numbers in U.S. databases, the amount of foreign operator effort required is reduced. The apparatus and method also reduces the losses to U.S. telephone companies due to foreign collect call processing errors and foreign collect calls fraudulently completed to pay telephones or other non-billable telephone numbers.
