Change DSCP Values for 7960/7940 Call Control & Configuration?

[ADB100]

Is there anywhere is CCM 3.3(5) where you can edit the DSCP Values the 7960/7940 uses for Call Signalling, Configuration & Services? In the Network Settings Menu on the IP Phones it displays the values that are used (or at least displays 'default') but is there anywhere in CCM you can edit these or is this a CCM 4.x feature?

Cisco's latest AVVID/QoS guidelines specify Call Signalling should be DSCP 24 (CS3) and not what was previously recommended of DSCP 26 (AF31). I have monitored the packets and by default (with the latest Phone Firmware 7.1(2)) it still uses DSCP 26 for signalling.

Thanks
