Chapter 6 Customizing the Cisco Unified IP Phone
Configuring the Idle Display
Note The Cisco Unified IP Phone 7931G does not support wideband handset.
The following parameters in Cisco Unified Communications Manager Administration affect whether
wideband is supported for this Cisco Unified Communications Manager server and a specific phone:
• Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
System > Enterprise Parameters. The default value of this enterprise parameter is True, which
means that all Cisco Unified IP Phones that are registered to this Cisco Unified Communications
Manager advertise G.722 to Cisco Unified Communications Manager. For more information, see the
Cisco Unified Communications Manager System Guide, Cisco Unified IP Phones.
• Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
Device > Phone. The default value for this product-specific parameter is the value that is specified
in the enterprise parameter. If you want to override this on a per-phone basis, choose Enabled or
Disabled in the Advertise G.722 Codec parameter on the Product Specific Configuration area of the
Phone Configuration window.
Configuring the Idle Display
You can specify an idle display that appears on the phone 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.
XML services that can be used as idle displays include company logos, product pictures, and stock
quotes.
Configuring the idle display consists of these general steps.
1. Formatting an image for display on the phone.
2. Configure Cisco Unified Communications Manager to display the image on the phone.
For detailed instructions about creating and displaying the idle display, see Creating Idle URL Graphics
on Cisco Unified IP Phone at this URL:

In addition, you can see the Cisco Unified Communications Manager Administration Guide or the 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 page, 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 page, or the Idle
Timer field in the Bulk Administration Tool (BAT)
