Abstract
Call spoofing in a Voice over Internet Protocol (IP) system may be detected and/or prevented. A device may receive a call request to initiate a VoIP call. The device may analyze marker information in the call request to determine whether the call request is valid. The device may also analyze the call request, based on call pattern information of a quantity of other calls, to determine whether the call request is suspicious; and complete the call based on the determination of whether the call request is valid and the determination of whether the call request is suspicious.
