Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Device Configuration Menu
Wideband Headset Indicates whether wideband is enabled
or disabled for the headset.
Default: Disabled
If Wideband Headset UI Control is
enabled, you or the user can use the
phone and choose
> User
Preferences > Audio Preferences >
Wideband Headset.
If Wideband Headset UI Control is
disabled, use Cisco Unified
Communications Manager
Administration > Device > Phone >
Phone Configuration to set this value.
If you allowed this option to be user
controllable (in the Wideband Headset
UI Control option), the user-configured
value takes precedence.
Enterprise
Advertise G.722
Codec
Enables/disables Cisco Unified IP
Phones to advertise the G.722 codec to
Cisco Unified Communications
Manager. If enabled (default), and if
each endpoint in the attempted call
supports G.722 in its capabilities set,
Cisco Unified Communications
Manager will choose G.722 for the call.
Note When a phone is registered
with a Cisco Unified
Communications Manager that
does not support this setting,
the default is “Disabled.”
Use Cisco Unified Communications
Manager Administration > System >
Enterprise Parameters.
Device Advertise
G.722 Codec
Allows you to override the Enterprise
Advertise G.722 Codec on a per-phone
basis.
The default is “Use System Default,”
which means the value configured for
the Enterprise Advertise G.722 Codec
parameter gets used.
Use Cisco Unified Communications
Manager Administration > Device >
Phone.
