Abstract
An automated method for determining the validity of an incoming phone call including receiving an incoming phone call, activating a controller in response to receipt of the incoming phone call, wherein the controller generates a multi-digit code in response to the receipt of the incoming call, outputs an audible version of the multi-digit code to a caller for the incoming call, requests the caller to input the multi-digit code, compares the multi-digit code with a caller input, determines the call is invalid in response to a mismatch between the multi-digit code and the caller input, and terminates the phone call.
