B. Toll fraud. Toll fraud is a type of VoIP attack where unauthorized individuals or entities gain access to a VoIP system and use it to make costly international or long-distance calls, often for financial gain. This can lead to substantial charges for the organization, as they are billed for the fraudulent calls.
