The controller also supports location queries for the clients that are not identified as voice clients on the
controller.
Voice over Remote Access Point
Voice traffic support is enhanced on split tunnel mode over a remote access point. The voice traffic management
for remote and local users are done on the controller. However, the sessions are created differently for both users.
For remote users, the sessions are created on the remote access point and for local users, the sessions are created
on the controller. This enhancement provides the following support for the voice traffic in the split tunnel over
remote access point:
 Voice traffic QoS is consistent for both local and remote users
 All voice ALGs work reliably in split tunnel mode when the PBX traffic is destined to flow through the
corporate network.
 Provides voice statistics and counters for remote voice clients in the split tunnel mode
The flag parameter in the show voice client-status command is updated to indicate remote users.

Battery Boost
Battery boost is an optional feature that can be enabled for any SSIDs that support voice traffic. This feature
converts all broadcast and multicast traffic to unicast before delivery to the client. Enabling battery boost on an
SSID allows you to set the DTIM interval from 10 - 100 (the previous allowed values were 1 or 2), equating to
1,000 - 10,000 milliseconds. This longer interval keeps associated wireless clients from activating their radios for
multicast indication and delivery, leaving them in power-save mode longer, and thus lengthening battery life. The
DTIM configuration is performed on the WLAN, so no configuration is necessary on the client.
An associated parameter available on some clients is the Listening Interval (LI). This defines the interval (in
number of beacons) after which the client must wake to read the Traffic Indication Map (TIM). The TIM
indicates whether there is buffered unicast traffic for each sleeping client. With battery boost enabled, the DTIM
is increased but multicast traffic is buffered and delivered as unicast. Increasing the LI can further increase
battery life, but can also decrease client responsiveness.
You can use the WebUI or CLI to enable the battery boost feature and set the DTIM interval in the SSID profile.
Using the WebUI
1. Navigate to the Configuration > AP Configuration page. Select either the AP Group tab or AP Specific tab.
 If you selected AP Group, click Edit by the AP group name for which you want to enable battery boost.
 If you selected AP Specific, select the name of the AP for which you want to enable battery boost.
2. Under Profiles, expand Wireless LAN, then select Virtual AP. In the Virtual AP list, select the appropriate
virtual AP instance.
