Description (partial)

When changing service parameter for DSCP (DSCP for Cisco Callmanager to device Interface) to CS5. The callmanager will not mark the packets towards gateway, even though we did the correct procedure to change the parameter.

Save/Apply/Reset, then go into each and every CUCM node and reset CCM services

For TCP connections it does mark the packets with the correct DSCP value
