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
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.
Tip
The PNG files for background images must meet the following requirements for proper display on the phone:
•
Full size image - 640 pixels (width) X 480 pixels (height).
•
Thumbnail image - 123 pixels (width) X 111 pixels (height).
If you are using a graphics program that supports a posterize feature for grayscale, set the number of tonal
levels per channel to 16, and the image posterizes to 16 shades of grayscale.
Tip
Phone Customization Tools
Third-party vendors provide tools that can be used to change aspects of the phone. These tools can be used
to customize ringtones and wallpaper for many of the Cisco IP Phones. For more information, see the third-party
vendor documentation and
Set Up Idle Display
You can specify an idle display (text only; text file size should not exceed 1M bytes) that appears on the phone
screen. The idle display is an XML service that the phone invokes when the phone is idle (not in use) for a
designated period and no feature menu is open.
For detailed instructions about creating and displaying the idle display, see
