[cisco-voip] QoS Packet Marking with IPCC Express

[Carter, Bill]

The IPCC Express SRND discusses QoS markings for IPCCx to CallManager,
and IPCCx to Agent Desktop.  

The guide states QoS markings should be the following:
	CTI Messaging between IPCCx JTAPI and CallManager - CS3
	Messaging between IPCCx and Agent Desktop - CS3

I can not find anywhere if the servers mark the packets appropriately,
of if at the switch/router level class-maps and policy-maps are required
to mark the packets.
