Parameter		Description	Quality
PacketLoss: NLR	Net packet Loss Ratio	The fraction of RTP data packets from the source lost since the beginning of reception.	The lower the better is the quality.
PacketLoss: JDR	Jitter buffer Discard Ratio
Jitter Buffer: JBA	Jitter Buffer Adaptive	3 = Adaptive Jitter buffer is used (Default setting Maxwell)
Jitter Buffer: JBN	Jitter Buffer Nominal	Current nominal jitter buffer delay in milliseconds.	The lower the better is the quality.
Jitter Buffer: JBM	Jitter 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: JBX	Jitter Buffer Abs Maximum	This 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)
