Abstract
A device includes a memory configured to store a first phone number indicated by a call invitation message. The device also includes one or more processors coupled to the memory and configured to receive, from a second device, the call invitation message associated with a call from the second device. The call invitation message indicates the first phone number as an originating phone number of the call. The one or more processors are configured to send, to the second device, a registry check request that includes the first phone number, and to receive, from the second device, a registry check response that indicates whether the first phone number is included in a registry associated with the second device. The one or more processors are configured to output a call spoofing indicator associated with the call and that is based on whether the first phone number is included in the registry.
