VoiPong is a sniffer that picks up on all sorts of VoIP protocols, decodes the traffic, and saves them to .wav files. How cool is that ? Looking at the site’s news and the file dates, the latest version is a couple of years old, which makes it even more stupefying that I’ve missed this.

There’s a Live CD too, if that’s the sort of thing you’re into. I’ll probably play with this a bit and if it’s a lot of fun (as it seems to be), I’ll post about it.
