Abstract
An apparatus including a plurality of packet processors each included in one of a plurality of voice-over-internet-protocol (VoIP) network interfaces. Each of the plurality of packet processors is configured to cache a latest version of realtime transport control protocol (RTCP) report data by discarding an older version of the RTCP report data. The RTCP report data includes at least one of RTCP sender report data and RTCP receiver report data. The apparatus also includes a packet data switching matrix configured to switch packet data between ones of the plurality of VoIP network interfaces. A central processor of the apparatus is configured to generate a final session detail record upon the termination of a VoIP-session by selecting RTCP session-concluding report data from a plurality of RTCP final report data each cached by a corresponding one of the plurality of packet processors.
