Hi All.

I implemented QOS on the LAN this weekend in our shop.  I configured 6 
closets running a slew of 3750's and four 6500 CAT switches (with a few 
6x48 blades).   I have one issue so far.  I'm sniffing one of the Call 
Manager interfaces on the switch and all packets coming into the 
CallManager seem to have the correct COS assigned.  All of the packets 
sourced by CallManager are COS = 0.  This makes it look like CallManager 
is changing these packets to 0.  Did I miss something on CallManager that 
I need to enable?   The clusterwide parameters (System - QOS) under 
Service Parameters is set to Normal Priority, EF, AF41 and CS3. 

Running CallManager 4.1.3sr5d

Thanks,
