HI
I have setup QoS on my LAN, however when i sniff my RTP stream from two 7912 phones i notices that they do not mark the packets with COS tag. How do i achieve this? SCCP seems to be fine but rtp is just like any other packet CoS is 0.
regards colin

Where is the point of sniffing ? Do you use SPAN/RSPAN feature ? Show config of the phone's switch port.
