Custom Background Images

You can provide users with a choice of background images (or wallpaper) for the LCD screen on their phones.
Users can select a background image by choosing Applications > Preferences > Wallpaper on the phone.
The image choices that users see come from PNG images and an XML file (called List.xml) that are stored
on the TFTP server that the phone uses. By storing your own PNG files and editing the XML file on the TFTP
server, you can designate the background images from which users can choose. In this way, you can provide
custom images, such as your company logo.
Attention All file names are case sensitive. If you use list.xml for the file name, the phone will not apply your
changes.
You can disable the option for users to select a background image by unchecking the Enable End User Access
to Phone Background Image Setting check box from the Common Phone Profile Configuration window in
Cisco Unified Communications Manager Administration (Device > Device Settings > Common Phone
Profile). When this check box is unchecked, the Applications > Preferences > Wallpaper option does not
display on the phone.
For more information, see the "Common Phone Profile Configuration" chapter in the Cisco Unified
Communications Manager Administration Guide.
