Configuring the Idle Display
Step 4 To cache the new DistinctiveRinglist.xml file, stop and start the TFTP service by using Cisco Unified
Serviceability or disable and re-enable the “Enable Caching of Constant and Bin Files at Startup” TFTP
service parameter (located in the Advanced Service Parameters).
Configuring the Idle Display
You can specify an idle display (text only; text-file size should not exceed 1M bytes) that appears on the
phone LCD screen. The idle display is an XML service that the phone invokes when the phone has been
idle (not in use) for a designated period and no feature menu is open.
For detailed instructions about creating and displaying the idle display, refer to Creating Idle URL
Graphics on Cisco Unified IP Phone at this URL:

In addition, you can refer to Cisco Unified Communications Manager Administration Guide or to Cisco
Unified Communications Manager Bulk Administration Guide for the following information:
• Specifying the URL of the idle display XML service:
–
For a single phone—Idle field on the Cisco Unified Communications Manager Phone
configuration window
–
For multiple phones simultaneously—URL Idle field on the Cisco Unified Communications
Manager Enterprise Parameters configuration window, or the Idle field in the Bulk
Administration Tool (BAT)
• Specifying the length of time that the phone is not used before the idle display XML service is
invoked:
–
For a single phone—Idle Timer field on the Cisco Unified Communications Manager Phone
configuration window
–
For multiple phones simultaneously—URL Idle Time field on the
Cisco
Unified Communications Manager Enterprise Parameters configuration window, or the
Idle Timer field in the Bulk Administration Tool (BAT)
From a phone, you can see settings for the idle display XML service URL and the length of time that the
phone is not used before this service is invoked. To see these settings, choose Administrator Settings
> Device Configuration and scroll to the Idle URL and the Idle URL Time parameters.
Automatically Disabling the Cisco Unified IP Phone Backlight
To conserve power and ensure the longevity of the phone screen backlight, you can set the backlight to
turn off when it is not needed.
You can configure settings in Cisco Unified Communications Manager Administration to turn off the
backlight at a designated time on some days and all day on other days. For example, you may choose to
turn off the backlight after business hours on weekdays and all day on Saturdays and Sundays.
You can take any of these actions to turn on the backlight any time it is off:
• Press any button on the phone.
The phone takes the action designated by that button in addition to turning on the backlight.
