Channel announcement and quite mode should be enabled.
In versions prior to 5.0, power constraint (TPC) was a configurable option. Power constraint should be left un-configured as
DTPC will be used by the Cisco Unified Wireless IP Phone 7925G to control the transmission power.

Call Admission Control Settings

To enable Call Admission Control (TSPEC), you must configure maximum bandwidth and roaming bandwidth percentages for
voice.
Maximum bandwidth default setting for voice is 75%, and 6% of that bandwidth is reserved for roaming clients.
Roaming clients are not limited to using the reserved roaming bandwidth, but is to reserve some bandwidth in case all other
bandwidth is utilized.
Will want to ensure load-based CAC is enabled, which is available in the 4.1 release for the Cisco Unified Wireless LAN
Controller, but not currently available on the autonomous access point platform.
Load-based CAC will account for non-TSPEC clients as well as other energy on the channel.
The AP1000 does not support load-based CAC as of release 4.1.185.0.
