Call Admission Control (Cac) - Cisco 6861 Deployment Manual

Configure the RADIUS servers to be used for authentication and accounting.

Call Admission Control (CAC)

Load-based CAC that supports multiple streams is 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 one stream and the stream size is not customizable, therefore SRTP
and barge do not work if CAC is enabled.
If Admission Control for Voice or for Video is enabled on the Cisco Autonomous Access Point, the admission must be
unblocked on the SSID as well. In recent releases, the admission is unblocked by default.
