[Users] different QoS tagging for voice and video RTP

I would like to tag my voice and video RTP with different QoS. If I'm using SER/OpenSER I can QoS tag RTP thru either the mediaproxy or rtpproxy. But that seem to currently tag both voice and video RTP with the same QoS. I can use iptables (on linux) to also tag a particular UDP port range with a particular DSCP value but again it seems difficult to differentiate voice and video RTP unless one tries to allocate voice RTP to one UDP range and video to another. Has anyone got any idea on how to achieve this? -- Dr. Rodney G.
