Chapter 6 Customizing the Cisco Unified IP Phone Creating Custom Background Images Creating Custom Background Images You can provide users with a choice of background images for the LCD screen on their phones. Users can select a background image by choosing Settings > User Preferences > Background Images 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 used by the phone. 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. The following sections describe how you can customize the background images that are available at your site by creating your own PNG files and editing the List.xml file: • List.xml File Format Requirements, page 6-5. • PNG File Requirements for Custom Background Images, page 6-6. • Configuring a Background Image, page 6-7 List.xml File Format Requirements The List.xml file defines an XML object that contains a list of background images. The List.xml file is stored in the TFTP server. For more information, see the "Cisco TFTP" chapter in Cisco Unified CallManager System Guide, Release 5.0(1) and the "Software Upgrades" chapter in Cisco IP Telephony Platform Administration Guide. 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.
