Abstract: A device, system and method for routing botnet calls to a botnet call-answer queue. A device, such as a call answering point (CAP) and/or a public-safety answering point (PSAP) router device, receives a call and determines an audio signature of the call. The device compares the audio signature of the call with one or more botnet audio signatures stored at a memory. In response to the audio signature of the call matching at least one of the one or more botnet audio signatures, the device: identifies the call as a botnet call that has been placed by a botnet; and cause the call to be routed to a botnet call-answer queue.
