Voip Capture

0

Hi,

I made this capture and i want to understand it:

Max delta = 35.92 ms at packet no. 83135 
Max jitter = 3.91 ms. Mean jitter = 1.03 ms.
Max skew = 26.09 ms.
Total RTP packets = 1436 (expected 1436) Lost RTP packets = -2872 (-200.00%) Sequence errors = 2872 
Duration 28.68 s (-17389 ms clock drift, corresponding to 3149 Hz (-60.63%),
what does it mean this?? why is -200.00%, and why sequence error? Cuz previously capture from another side, percent represent the amount of lost, but positive not negative like in this case. VoIP quality is good. So i just wanna know what this means.

It means that you spanned a vlan and you captured the media packets twice, once in ingress, once on egress.
