Hi Eric, SIPp doesn't currently support many statistics on RTP packets (though it's something I might consider adding in the future). Until then, in your situation, what I'd probably do is to capture all the RTP packets with Wireshark/tcpdump, then write a small program using Python and scapy (or similar tools, like rubypcap or jNetPcap, if you prefer other languages) to retrieve the packets, separate them out into calls, process the streams to calculate packet loss/delay/ordering issues, and generate some sort of statistical report.
If you end up writing (or finding) a tool like that, do consider emailing the list to let others know - I think it's something that others would find useful, and I'd be happy to link to it from the SIPp docs. It might also be worth making a sample of your RTP capture available, so that anyone else on the list who knows of such a tool (or might want to write one) can see if it's suitable. Hope that helps, Rob On 2 February 2014 15:45, Eric Lenington <e...@telelero.com> wrote: > Hello, > > I'm relatively new to SIPp.
