Hi Pietro,

The TX9000 (and all CTS Codecs) will use the DSCP value configured on the Call Manager for TelePresence calls, and the default value for this is CS4. You can check this value on the codec by logging onto the GUI of the codec and clicking the "Telephony Settings" link on the left hand side.

If you need to change this setting you can do so by logging onto the CUCM GUI and navigating to System > Service Paramaters > Server: Select a server, Service: Cisco CallManager > DSCP For TelePresence Calls.

You will need to apply config or reboot the TX9000 for the changes to take affect.

Thanks,

Paul
