• Be sure that voice and call control packets have the proper QoS markings and other protocols are not using the same
QoS markings.
• Select the Platinum QoS profile for the voice wireless LAN when using Cisco Unified Wireless LAN Controller
technology and set the 802.1p tag to 6.
• Enable Differentiated Services Code Point (DSCP) preservation on the Cisco IOS switch.
For more information about TCP and UDP ports used by the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G
and the Cisco Unified Communications Manager, refer to the Cisco Unified Communications Manager TCP and UDP Port

Configuring QoS in Cisco Unified Communications Manager
The SCCP DSCP values are configured in the Cisco Unified Communications Manager enterprise parameters. Cisco Unified
Communications Manager uses the default value of CS3 to have devices set the DSCP marking for SCCP packets as shown in
the Enterprise Parameters Configuration page.
Configuring QoS Policies for the Network
Configure QoS policies and settings for the following network devices.
Configuring Cisco Switch Ports
Configure the Cisco Unified Wireless LAN Controller and Cisco Access Point switch ports as well as any uplink switch ports.
