Chapter 6 Customizing the Cisco Unified IP Phones
Creating Custom Background Images
The following sections describe how you can customize the background images that are available at your
site by creating your own PNG files and editing the List.xml file:
• List.xml File Format Requirements, page 6-4.
• PNG File Requirements for Custom Background Images, page 6-5.
• Configuring a Custom Background Image, page 6-5
Note The XSI Screen Width Enhancement feature, when implemented on Cisco Unified IP Phones, enhances
the viewability of the Messages, Directories, and Services screens. These screens may appear in Normal
mode or in Wide mode, depending on how the phone is set up. For information, see
Cisco Unified IP
Phone Services Application Development Notes.
List.xml File Format Requirements
The List.xml file defines an XML object that contains a list of background images. The List.xml file is
stored in the following subdirectory on the TFTP server:
/Desktops/320x196x4
Tip If you are manually creating the directory structure and the List.xml file, you must ensure that the
directories and files can be accessed by the user\CCMService, which is used by the TFTP service.
For more information, see Software Upgrades in Cisco Unified Communications Operating System
Administration Guide.
The List.xml file can include up to 50 background images. The images are in the order that they appear
in the Background Images menu on the phone. For each image, the List.xml file contains one element
type, called ImageItem. The ImageItem element includes these two attributes:
• Image—Uniform resource identifier (URI) that specifies where the phone obtains the thumbnail
image that will appear on the Background Images menu on a phone.
• URL—URI that specifies where the phone obtains the full size image.
The following example shows a List.xml file that defines two images. The required Image and URL
attributes must be included for each image. The TFTP URI that is shown in the example is the only
supported method for linking to full size and thumbnail images. HTTP URL support is not provided.
List.xml Example
<CiscoIPPhoneImageList>
<ImageItem Image=”TFTP:Desktops/320x196x4/TN-Fountain.png”
URL=”TFTP:Desktops/320x196x4/Fountain.png”/>
<ImageItem Image=”TFTP:Desktops/320x196x4/TN-FullMoon.png”
URL=”TFTP:Desktops/320x196x4/FullMoon.png”/>
</CiscoIPPhoneImageList>
The Cisco Unified IP Phone firmware includes a default background image. This image is not defined
in the List.xml file. The default image is always the first image that appears in the Background Images
menu on the phone.
