To address the growing problem of telephone fraud, Sprint has introduced a customer protection program to its business customers, limiting their liability for toll fraud to the first $25,000.
Abstract
Sprint then assumes liability for the cost of fraudulent calls up to $1 million. The plan includes a range of preventive features. AT&T and MCI have introduced similar plans. Sprint's efforts have focused on fraud involving calling cards, PBX, and voice mail. It addressed card fraud by lengthening card numbers to 14 digits and implementing sophisticated network fraud detection systems. To address other fraud, it requires that participating businesses implement several security measures. They must use at least eight digits for each direct inward system access code, eliminate all external call-transfer capabilities for voice mail, install a security system on all remote maintenance ports for customer premises equipment, and delete all default passwords installed by manufacturers and vendors. Sprint uses sophisticated computer programs to monitor a business's telecommunications flow to detect fraud. Two major current scams are Amigo and call-sell operations, both of which are used to call people in other countries. Sprint is also working with its customers to develop programs to deal with another vulnerable area, cellular phones. Footnotes
