Hi Luca,

Thanks a lot for the reply. Is there any settings for ntop to enable that
VoIP analysis. I'm using the newest version v4.0. But I can't see the ntop
is analyzing the VoIP call. The only thing I saw is the skinny traffic
trend. We are using cisco phone systems.

So nProbe offers more feature for the VoIP traffic analysis, right?

Thanks.

Lou
