This can be changed in the administration of CCM System Settings business. You can check to see if values ​​have changed. Also, make sure that these packages are not seen in any other part of the network.

HiYes - as I mentioned before, your CCM port must be configured to trust DSCP 'qos trust dscp' not trust COS.COS is a marking in the dot1q or ISL header of a packet - as the CallManager is not on a trunked port like phones are, it can NOT mark COS on packets.Also you wouldn't normally have 'switchport voice vlan' on the port to CallManager as it is an access port in that VLAN.RegardsAaronPlease take the time to rate helpful posts...

HiAlso if you are sniffing at the downstream (phone) end it would be worth verifying that you have both enabled qos and set the port trust state on the port the CM is attached to to 'trust DSCP'.RegardsAaronPlease rate helpful posts...
