liarliar.sourceforge.net gives you something, its still in development. When
I looked at it a while ago I couldn't get anything useful from it, but I only
spent like 5-10 minutes on it. 

At some stage I was thinking about hooking liarliar up to asterisk to see if
the concept would work. A friend of mine raised the point that some codecs 
won't give you the info you're after most likely over IP, so I never looked
further into it.
