To change these options, use Cisco Unified CallManager Administration.
For an available Cisco Unified CallManager server, an option on the CallManager
Configuration menu will show the Cisco Unified CallManager server IP address
or name and one of the following states:
• Active—Cisco Unified CallManager server from which the phone is
currently receiving call-processing services.
• Standby—Cisco Unified CallManager server to which the phone switches if
the current server becomes unavailable.
• Blank—No current connection to this Cisco Unified CallManager server.
An option may also display one of more of the following designations or options:
• SRST designation—Indicates a Survivable Remote Site Telephony router
capable of providing Cisco Unified CallManager functionality with a limited
feature set. This router assumes control of call processing if all other
Cisco Unified CallManager servers become unreachable. The SRST
Cisco Unified CallManager always appears last in the list of servers, even if
it is active.
You configure an SRST router address in the Cisco Unified CallManager
Administration SRST Reference Configuration page (choose System >
SRST). You configure an SRST reference in the Device Pool Configuration
page (choose System > Device Pool).
• TFTP designation—Indicates that the phone was unable to register with a
Cisco Unified CallManager listed in its configuration file and it registered
with the TFTP server instead.

connection to the Cisco Unified CallManager is authenticated. For more
information about authentication, refer to Cisco Unified CallManager
Security Guide.
