Cisco Unified Wireless IP Phone 7921G Series Deployment Guide 46
Application Button Priority
If the priority is low, then will only function when the keypad is unlocked and on
the home screen. Medium priority will allow the application button to function
when in any menu or XML screen and high priority will allow the application
button to function when in any state including keypad lock.
Out of Range Alert
An out of range alert can be configured to beep once or periodically to audibly
notify the user that they have traveled out of the coverage area.
Scan Mode
Scan mode allows for auto, continuous, and single AP options, where auto
primarily scans only when on call and single AP only at power on.
Restricted Data Rates
The restricted data rates feature utilizes the Traffic Stream Rate Set (TSRS)
information element from CCX v4, which can define a data range (upper and
lower) for the client to use (i.e. 12 - 24 Mbps). This can be beneficial for
environments that have legacy clients requiring lower data rates to be enabled on
the access point, but also preventing other clients from downshifting to lower rates,
which lowers overall throughput and capacity. When enabled the Cisco Unified
Wireless IP Phone 7921G will not transmit below 12 Mbps for 802.11a and 11
Mbps for 802.11b/g.
Power Off When Charging
Power off when charging feature will power off the phone when placed on AC
power.
Cisco Discover Protocol (CDP)
Enables or disables CDP.
Advertise G.722 Codec
G.722 capabilities can be configured on a phone by phone basis and optionally
override the system default.
Home Screen
By default the Cisco Unified Wireless IP Phone 7921G will show the traditional
screen with the four icons for directory, services, settings and line access.
FIPS Mode
The Federal Information Process Standards (FIPS) mode can optionally be enabled.
Auto Line Select
When enabled, indicates that the phone will shift the call focus to incoming calls on
all lines. When disabled, the phone will only shift the focus to incoming calls on
the currently used line.
Minimum Ring Volume
This parameter controls the minimum ring volume on the phone. This value is set
by the administrator, and can not be changed by an end user. The end user can
increase the ring volume, but may not decrease the ring volume below the level
defined. The minimum ring volume range is from 0 to 7, with 0 (silent) being the
default value.
