Patent ID: 8599747

Claim:
A method of conducting a lawful intercept of real time media packet traffic with low latency and detection avoidance, comprising: directing real time media packet streams between a caller and callee through a media server, the media server being dedicated to the lawful intercept of real time media packet traffic; replicating the media packet streams within the media server, the replication resulting in original media packet streams and replicated media packet streams; forwarding, using the media server, the original media packet streams between the caller and the callee; modifying address and port information in packet headers of the replicated packet streams, without encapsulating packets of the replicated packet streams or modifying payload data of the replicated packet streams so as to reduce latency and avoid detection, wherein the modifications comprise: changing a source address to an address of the media server; changing a source port to a source port of the media server; changing a destination address to an address of a monitoring system; and changing a destination port to at least one monitoring port; and directing, based on the modified address and port information, the modified packet streams to the at least one monitoring port.
