there was an application called sip-scenario written in perl, which
generated browsable static html files from a pcap file, all in a folder
that could be easily archived and sent over to others.

It is referenced from:

  - https://www.voip-info.org/wiki/view/SIP+Scenario

It is pointing to iptel.org, which seems to be down (I should ask the
guys behind it why). It was not written by iptel.org guys, they just
hosted a copy.

I should still have a copy somewhere myself as well, but, iirc, it
throws some errors with the last Perl. I used quite extensively at some
point, before sngrep. It created the diagram in an html page, allowing
to click on the arrows to view the text sip message in another frame
(a-la sipcapture). It was on my plan to try to fix it few years ago, but
no much time and lack of proper Perl knowledge kept me away, then sngrep
popped up, etc.

Should anyone be interested, maybe I should dig for it and push to a
github repo where people can grab/fix/contribute/fork.
