If you do it with tapping it can in real time. The intention is to eventually
include a "dump to csv" button similar to the RTP analysis one, which would probably
serve for your purposes. What I'm afraid of is the "call status" thing. If you consider
a SIP call that has three dialogs, one of them with a change of media, the second 
closed and the third being transferred, choosing between "in progress", "completed",
or whichever states you have doesn't seem possible. And for H323 the number of
protocols involved is discouraging.
