Hi,
I sent a proposal for the implementation some days ago, with some comments on issues, in:
http://www.ethereal.com/lists/ethereal-dev/200410/msg00146.html
but I have received no feedback. Right now it works for SIP and ISUP over MTP3.

What I sent has "protocol", "calling id", "called id", "status", "number of packets", "starting time" and "comments". It does not have the IP:port A and IP:port B -it does have an "initial speaker" - because that focuses on calls where only two parties are involved. If you have a SIP call with a couple of proxies it is hard to say which are the correct A and B to put there.

Te code I sent has a "Filter" button that ORs the data of one conversation to the generic display filter. This is because I think that it can be more useful to do the "analysis" stuff independent, you that you can use it for other protocols. So right now you can select a call, add it to the filter, do the same with two calls more, then apply the filter and see the calls in the main window.

That would also be easier if we separate the "conversation list" function from the "flow display" stuff.
