Optimized Voice Settings

By using the Admission Control check boxes, you can control client use of the
access categories. When you enable admission control for an access category,
clients associated to the access point must complete the WMM admission
control procedure before they can use that access category. However, access
points don’t support the admission control procedure in this release, so clients
cannot use the access category when you enable Admission Control.

Configuring Call Admission Control

Configuring Call Admission Control (CAC) on an access point involves the
following:

1. Configuring the radio.
2. Enabling admission control on an SSID.

Follow these steps to configure admission control on an access point’s radio.

For a list of Cisco IOS commands for configuring admission control by using
CLI, see the

Cisco IOS Command Reference for Cisco Aironet Access Points

and Bridges Guide

.

1. Click the Access Categories page of the radio you want to configure.

Figure 114 on page 473

shows an example of an Access Categories page.

2. Check Admission Control under Voice(CoS 6-7).
3. Enter the maximum percentage of the channel to be used for voice in the

Max Channel Capacity (%) field.

4. Enter the maximum percentage of the channel to use for roaming calls in

the Roam Channel Capacity (%) field.

The percentage of the channel used by roaming calls up to the value specified in
this field is deducted from the value you specified in the Max Channel Capacity
(%) field.

For example, suppose you have entered 75% in the Max Channel Capacity (%)
field and 6% in the Roam Channel Capacity (%). If roaming calls are using 5% of
the channel, a maximum of 70% of the channel can be used for voice.

IMPORTANT

The above rates work fine for Cisco phones. Third parties wireless phones can
have a different nominal rate or minimum PHY rate. You need to enable
additional nominal rates for these phones.
