I guess I am amongst VoIP addicts and other strange creatures here on the forum. So I assume I am save by revealing some of the tools I am using. (This is gonna come back and bite me)
that one looks interesting, its free and it seems like a good way to keep logs of calls made besides analyzing them...
I suppose it examines the voip traffic only on your LAN, ie. only internal calls, wonder if it works for remote calls also (when the called side is not on LAN), it picks my curiosity anyway, will get it and see if it will do something for me I suppose
