Nope, you can't do that, because the transport stream is defined as src/dst port dinamically by the VoIP control channel, be it H.323/SIP/MGCP/Skinny/whateva. The only feasible way is to set ToS/DSCP into the VoIP endpoints/applications. I've seen many devices allowing you to set up speciffic ToS for the RTP stream. Well, of course you could you some sort of l7 classification, but that is speciffic to your needs. > Thank you [ cut ] Regards, Nickola
