Cisco 7975G Software Guide

Two parameters in Cisco Unified Communications Manager Administration affect whether wideband is
supported for this Cisco Unified Communications Manager server or 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 Phone models that are described in this administration guide and are registered to this
Cisco Unified Communications Manager will advertise G.722 to Cisco Unified Communications Manager.
For more information, see the Cisco Unified Communications Manager System Guide, “Cisco Unified
IP Phones” chapter.
•
Advertise G.722 Codec: From Cisco Unified Communications Manager Administration, choose Device
> Phone. The default value of this product-specific parameter is to use the value specified in the enterprise
parameter. If you want to override this on a per-phone basis, choose Enabled or Disabled in the advertises
G.722 Codec parameter on the Product Specific Configuration area of the Phone Configuration window.
Idle Display Setup
You can specify an idle display 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.
XML services that can be used as idle displays include company logos, product pictures, and stock quotes.
Configuration of the idle display requires these general steps:
1
Format 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, see the Cisco Unified Communications Manager Administration Guide or the Cisco Unified
Communications Manager Bulk Administration Guide for the following information:
•
Specify the URL of the idle display XML service:
◦
For a single phone: Idle field in 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)
•
Specify 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)
