Description and Usage GuidelinesDefaultField Type
or Choices
Field Name
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.
• Normal—Detection of a Unified CM connection failure
occurs at the standard system rate. Choose this value for
faster recognition of a Unified CM connection failure.
• Delayed—Detection of a Unified CM connection failover
occurs approximately four times slower than Normal.
Choose this value if you prefer failover to be delayed
slightly to give the connection the opportunity to
reestablish
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.

Connection Failure
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.

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.
