DescriptionQuality
PacketLoss: NLRNet packet Loss RatioThe fraction of RTP data packets from the source lost since the beginning of reception.The lower the better is the quality.
PacketLoss: JDRJitter buffer Discard Ratio

Jitter Buffer: JBAJitter Buffer Adaptive3 = Adaptive Jitter buffer is used (Default setting Maxwell)
Jitter Buffer: JBNJitter Buffer Nominal Current nominal jitter buffer delay in milliseconds.The lower the better is the quality.
Jitter Buffer: JBMJitter Buffer Max Current maximum jitter buffer delay in milliseconds (in this case, the adaptive jitter buffer is used).The lower the better is the quality.
Jitter Buffer: JBXJitter Buffer Abs MaximumThis delay is the absolute maximum in milliseconds that the adaptive jitter buffer can reach under worst-case conditions.
it is the Maximum default value of the Jitter buffer settings. (400 ms, default setting Maxwell)
QualityEst: MOSCQConversation QualityThe higher the better.
