Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5

Chapter 6 Customizing the Cisco Unified IP Phone
Configuring Wideband Codec
Configuring Wideband Codec
If Cisco Unified Communications Manager has been configured to use G.722 (G.722 is enabled by
default for the Cisco Unified IP Phone) and if the far endpoint supports G.722, the call can connect using
the G.722 codec in place of G.711. This situation occurs regardless of whether the user has enabled a
wideband headset or wideband handset, but if either the headset or handset is enabled, the user may
notice greater audio sensitivity during the call. Greater sensitivity means improved audio clarity but also
means that more background noise can be heard by the far endpoint—noise such as rustling papers or
nearby conversations. Even without a wideband headset or handset, some users may prefer the additional
sensitivity of G.722. Other users may be distracted by the additional sensitivity of G.722.
The following 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 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, chapter Cisco Unified IP Phones, section
Codec Usage.
• 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 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.
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, refer to Creating Idle URL
Graphics on Cisco Unified IP Phone at this URL:
http://www.cisco.com/warp/public/788/AVVID/idle-url.html
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)
