VoIP, Internet Telephony Traffic

[rms <rms () telekom yu>]

Hi, List users,

Is it possible to detect VoIP/IP telephony traffic using Snort?

What are the main characteristic on which one could base the rules?

I don't want to listen but just to detect which computers on my network are 
using this type of traffic...

Is it better to scan the boxes looking for particular open ports? If so - 
which ones?

Hope this is not too off topic.

TIA

R.Soskic
