Abstract
A method, a communication device, and a computer program product for identifying a live phone call. The method includes receiving, at a first communication device, an activation of a verification mode for a phone call. The method includes receiving, from a second communication device on the phone call, first audio data associated with the phone call. The method further includes determining, via a processor of the first communication device, if the first audio data contains machine originated audio, and in response to determining that the first audio data does not contain machine originated audio, generating and outputting an alert that the phone call is live.
