With this session we intend to demonstrate how Wireshark can be used to analyze VOIP exchanges.
We will present the different steps of an VOIP connexion with the help of Wireshark. We will use three profiles (SIP, RTP and VOIP) to highlight the most important elements and we'll detail the colors, columns, filters, buttons used in these profiles .
We’ll browse the different tools available in Wireshark ( Statistics, graphs, RTP analysis) to further analyze some examples, including some disfunctioning samples.
