Item Description
Host names or IP addresses, in prioritized order, of the Cisco Unified Communications
CUCM Server 1–5
Manager servers with which the phone can register. An item can also show the IP
address of an SRST router that is capable of providing limited Cisco Unified
Communications Manager functionality, if such a router is available.
For an available server, an item shows the Cisco Unified Communications Manager
server IP address and one of the following states:
• Active: Cisco Unified Communications Manager server from which the phone
• Standby: Cisco Unified Communications Manager server to which the phone
• Blank: No current connection to this Cisco Unified Communications Manager
An item may also include the Survivable Remote Site Telephony (SRST) designation,
which identifies an SRST router capable of providing Cisco Unified Communications
Manager functionality with a limited feature set. This router assumes control of call
processing if all other Cisco Unified Communications Manager servers become
unreachable. The SRST Cisco Unified Communications Manager always appears
last in the list of servers, even if it is active. You configure the SRST router address
in the Device Pool section in Cisco Unified Communications Manager Configuration
window.

Directories URL URL of the server from which the phone obtains directory information.
Messages URL URL of the server from which the phone obtains message services.

Alternate TFTP Indicates whether the phone is using an alternative TFTP server.
Forwarding Delay Indicates whether the internal switch begins forwarding packets between the PC port

delay is set to disabled, the internal switch begins forwarding packets immediately.
When forwarding delay is set to enabled, the internal switch waits eight seconds
before forwarding packets between the PC port and the SW port. You should set
forwarding delay to enabled when you connect both ports to switches for redundant
uplinks or when you daisy-chain phones together.
Idle URL URL that the phone displays when the phone is idle for the time that the Idle URL
Time field specifies and no menu is open.
