Default Description and Usage Guidelines
Normal Determines the sensitivity that the phone has for detecting a
connection failure to Cisco Unified Communications Manager
(Unified CM), which is the first step before device failover to
a backup Unified CM/SRST occurs.
The precise time difference between Normal and Delayed
connection failure detection depends on many variables that
are constantly changing.
This field only applies to the wired Ethernet connection.
Enabled Allows the phone to negotiate power using Link Level
Endpoint Discovery Protocol (LLDP) and Cisco Discovery
Protocol (CDP).
Power Negotiation should not be disabled when the phone is
connected to a switch that supports power negotiation. If
disabled, the switch could shut off power to the phone.
Disabled Controls whether the user hears dial tone when the Release
key is pressed.
Specifies the default wallpaper file. When a default wallpaper
is set, the user can't change the phone wallpaper.
Disabled Controls the user interface for off-hook dialing. When enabled,
the user cannot select a number from the recent calls list.
When enabled, this field provides a simplified window for the
user to place a call. The user does not see the call history
pop-up window that is displayed when the phone is taken
off-hook. The pop-up window display is considered useful, so
Simplified New Call UI is disabled by default.
