I'm having a bit of trouble interpreting the jitter_ related data that I am getting out of XML CDR's in an attempt to measure how well a system is performing. For example, I place a G.711 call over a private LAN between two idle systems using PCMU, the originator being static in a continuous loop, and the destination being "echo", with jitterbuffer_ms=60:200:20 At the 'echo' end, I examine the call-stats section of the XML CDR (below), and I am not sure what to make of the jitter_ values -- for example max_variance of 7076.55, and a loss_rate of 116.67 -- as I haven't been able to determine from the source code thus far what they are measuring, and what units they are working in. Any pointers would be appreciated.
