Going to put my Call manager and Unity units on a 4507. Need to make sure that the DSCP markings are correct. Also have a trunk port on this 4507 that the WAN router is connected to. On my 6509 hybrid I have trust qos dscp on the port for the WAN router and trust cos on the ports for Unity and CCM. Shouldn't I be able to trust DSCP on the ports for CCM and Unity too? For example, the default on the 4507 is QOS disabled gobal and that looks like it enables trust dscp on all interfaces.
R-VIS4507-1#sh qos interface gigabitEthernet 3/8
QoS is disabled globally
Port QoS is enabled
Administrative Port Trust State: 'untrusted'

4 31250000 disabled N/A 260
Note this looks like dscp trust is enabled on all ports. Am I good here?
WHine alert !!! What happened to the documentation page on CCO. I can't find anything good regarding config help lately. Like how to turn on the qos globaly on the 4507.
