The Flow Chart (Call Flow) is a visualization mode in Snooper that shows a diagram of an SIP-based communication or call. Although it does not add information to what we already see in the messages, this kind of outline is helpful in examining the various steps of the call in a single view. We will see a couple of examples in this section.
- Launch Snooper, open a logfile, and go to messages, as we have seen in the previous section.
- Select a message on the left and then click on the Show Call Flow window option in the top-right menu, as shown in the following screenshot:
- In the first example, we have a conversation between a Lync client in the internal network and a Skype user (federation), as shown in the following screenshot:
- The second example is a call from a Lync client to a mobile phone, as shown in the following screenshot:
In the post Lync Media Conferencing/Audio call flow of Sip and SDP at http://digitalbamboo.wordpress.com/2013/08/17/lync-media-conferencingaudio-call-flow-of-sip-and-sdp/, we take an interesting deep dive on the call flow in Lync.
