Cisco Ip Phone 8800 Series Administration Guide For Cisco Unified Communications Manager - Cisco 8800 Series Administration Manual

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 the documentation for your particular Cisco Unified Communications Manager
release.
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 appears 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/800x480x24/TN-Fountain.png"
URL="TFTP:Desktops/800x480x24/Fountain.png"/>
<ImageItem Image="TFTP:Desktops/800x480x24/TN-FullMoon.png"
URL="TFTP:Desktops/800x480x24/FullMoon.png"/>
</CiscoIPPhoneImageList>
The phone firmware includes a default background image. The List.xml file does not define this image. The
default image is always the first image that appears in the Background Images menu on the phone.
Each background image requires two PNG files:
• Full size image: Version that appears on the on the phone.
• Thumbnail image: Version that displays on the Background Images screen from which users can select
an image. Must be 25% of the size of the full-size image.
Many graphics programs provide a feature that resizes a graphic. An easy way to create a thumbnail image
Tip
is to first create and save the full-size image, then use the sizing feature in the graphics program to create
a version of that image that is 25% of the original size. Save the thumbnail version by using a different
name.
The PNG files for background images must meet the following requirements for proper display on the phone:
• Full size image - 800 pixels (width) X 480 pixels (height).
• Thumbnail image - 139 pixels (width) X 109 pixels (height).
If you are using a graphics program that supports a posterize feature for grayscale, set the number of tonal
Tip
levels per channel to 16, and the image posterizes to 16 shades of grayscale.
