Hi,
I was running a very small SIPp load test: sipp -sf uac.xml -i [xxx] -p [yyy] [uas-ip]:[yyy] -t t1 -m 500 -l 100 -r 5
with packet capture running in the background: tcpdump -i andy -s0 -vvv -w uac.pcap
Then after the load test is done, I turned off the tcpdump and ran it through tshark: tshark -nr uac.pcap -q -z rtp,streams
I notice that the QoS measures are pretty out of wrack: - Packet loss is in the negatives - Max delta is 21 ms - Max Jitter is 20K ms - Mean Jitter is 3K ms
The instances I ran on are very powerful EC2 instances. It makes me wonder if my setup's performance is really shitty or there's something wrong with the way I measure QoS on a SIPp load test
