VoIP Record Bytes
Many VoIP protocols allow for logical groupings of packets, such as encapsulating multiple RTP datagrams within a single RTCP packet. This column provides a byte count of such logical groupings records. Contrast with the Packet Bytes column, which gives a byte count of actual packets regardless of logical groupings. Note that record byte counts only track TCP or UDP data, whereas the Packet Byte count includes encapsulating header information.
