What is cvVoIPCallHistoryEarlyPackets?

This AbsoluteCounter32, in packets, counts voice packets that arrived too early to be stored in the jitter buffer during the call. Administrators use this to detect jitter-buffer sizing problems caused by unusually fast or bursty packet arrival, which can cause the same kind of audio artifacts as late packets. For example, a call showing many early packets alongside quality complaints might indicate the jitter buffer is undersized for the traffic pattern seen on that path.
