1. A method, comprising:
determining one or more instances that an outbound call placed by a mobile device, subscribed to a protected network, includes a destination number that was stored in a call history of the mobile device as one or more of a call received number and a called number;
determining whether a confirmation response was sent to the destination number in response to a previous call received at the mobile device from the destination number;
determining the destination number is a scam call suspect number, based on the one or more instances being less than a threshold number of instances and there being no confirmation response sent; and
forwarding a scam call notification to the mobile device during the outbound call and prior to connecting the call, based on the determination that the destination number is a scam call suspect number.
