Abstract Text:The present invention provides a system, method and apparatus for automatically classifying voice communications, such as voice messages and phone calls in prerecorded voicemails (one speaker) and two-way conversations, as either spam or legitimate signals in a communications system (e.g., SIP, IMS, UMA, etc.). More specifically, the present invention classifies a voice communication session by receiving one or more voice communication packets associated with the voice communication session, extracting one or more properties from the received voice communication packets and classifying the voice communication session based on the extracted properties. The present invention can also be implemented as a computer program embodied on a computer readable medium wherein each step is performed by one or more code segments.
