Background Images
The list of available background images is specified in a file calledDesktops/WIDTHxHEIGHTxDEPTH/List.xml which the phone downloads from the provisioning server. The width, height and depth are determined by the capabilities of the phone's display. A maximum of 50 <ImageItem> entries can be specified.<CiscoIPPhoneImageList>
