Packet

Packet number. For RTP/RTCP rows, this is the first packet in that row.

Message

There is one set of messages per signaling flow. If a call has multiple signaling flows (i.e. H.225/Q.931, and H.245), there will be multiple sets of messages. Each new message in the signaling flow increments the message index.

 

You can use the Message index and the Flow Index together to get an understanding of the sequence of events on multiple signaling channels for a single call.
