Lisa Bock evaluates a SIP packet capture and evaluates some of the tools and charts for VoIP in CloudShark. Then, in Wireshark, Lisa compares SIP Statistics with SIP flows and flow sequence.
- [Instructor] When working with Wireshark…and voice over IP, we can take a look at SIP statistics…and some of the SIP flows.…Now I'm in CloudShark and I have a packet capture here.…Now within CloudShark there are some analysis tools.…I'll drop this down, and here you can see…voice over IP calls.…Now, here we can see some of the calls that we have,…and we'll tell the protocols…and what is happening in that specific conversations.…
But down below here in the lower left-hand corner,…I could go SIP Statistics,…and it gives me a nice graph as to what's happening…as far as the request method.…And different codes in the reply method…and some of the setup times.…So that's pretty handy…if you wanted to just do a spot check.…In addition, taking a look at graphs, I have a filter here…and in CloudShark I can do a quick SIP filter.…And you can do a graph…if you go Current Display Filter,…and that will give you a quick graph…of the display filter and so you can use it to compare…and save it to do an analysis later.…
