When enabling Call Admission Control on the Cisco Autonomous Access Point, the admission must be unblocked on the SSID

as well.

It is required to enable Call Admission Control on the SSID configuration, regardless of Admission Control being enabled for

Voice or Video.

Load-based CAC and support for multiple streams are not present on the Cisco Autonomous Access Points therefore it is not

recommended to enable CAC on Cisco Autonomous Access Points.

The Cisco Autonomous Access Point only allows for 1 stream and the stream size is not customizable, therefore SRTP and

barge will not work if CAC is enabled.

Also ensure that the PHY rate configured on the Cisco Unified IP Phone 9971is enabled as a nominal rate in the STREAM

configuration of the Cisco Autonomous Access Point.

It is recommended to use the defaults, where 5.5, 6.0, 11.0, 12.0 and 24.0 Mbps are enabled as nominal rates for 802.11b/g and

6.0, 12.0 and 24.0 Mbps enabled for 802.11a.

If enabling the STREAM feature either directly or via selecting Optimized Voice for the radio access category in the QoS

configuration section, ensure that only voice packets are being put into the voice queue. Signaling packets (SCCP) should be

put into a separate queue. This can be ensured by setting up a QoS policy mapping the DSCP to the correct queue.

For more information about Call Admission Control and QoS, refer to the Configuring QoS chapter in the Cisco IOS Software

Configuration Guide for Cisco Aironet Access Points at this URL:

In the Media settings, Unicast Video Redirect and Multicast Direct Enable should be enabled.
