1. An apparatus comprising:

  • a network processor capturing substantially all packets on at least one link of a packet network in real-time to thereby capture multiple communications transmitted via packets on said at least one link, each communication having corresponding signaling packets and at least one corresponding packet media stream; and

    a host system communicating with the network processor to filter the captured packets to thereby separate the signaling packets from the packet media streams, analyze the separated signaling packets to identify the communications, obtain respective packet media streams corresponding to captured communications from the separated packet media streams in accordance with a trigger applied to the identified communications, produce flow information records for the obtained packet media streams, and analyze the flow information records.
