Wireshark will give you a ladder diagram for a call. Pull down the
"Telephony" menu and select "VoIP calls". That will give you a list
of all VoIP calls represented in the packet dump.

Next, click on a call and then the "Flow" button. That will give you
a diagram very similar to the ladder diagram in your web page.

I'm often amazed at just how much Wireshark can do!
