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.
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 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.
Each background image requires two PNG files:
Full size image—Version that appears on the on the phone.
•
Thumbnail image—Version that appears on the Background Images screen
•
from which users can select an image. Must be 25% of the size of the full size
image.
