AT&T on Tuesday introduced a new service for automated fraud and spam call-blocking. They're calling it Call Protect, and the system works like an email spam filter—identifying numbers believed to be associated with fraud and either blocking them or flagging them with a warning.
Also like other spam filters, users will be able to whitelist specific numbers to rectify any false positives, and even set temporary call blocking for unconfirmed spam calls. These more granular controls will be accessible from the Call Protect companion app on iOS and Android devices.
