Uploading a New Background Image to Call Manager – Step by Step
NOTE: This is an example for the 8841 series phone
- Download the Background Image and Thumbnail and get them in the appropriate size (paint works well)
- Background: 800x480x24
- Thumbnail: 139×109
- Open the CLI of Call Manager and view the “List.xml” file which provides the phone with a list of available background image

- Copy and Paste the output into a text file
- Add a line at the bottom including your new background image (follow the standard of the others)
- Save the file as “List.xml”
- Be sure it is not a TXT file
- Upload the List.xml file to the Call Manager nodes running the Cisco TFTP service (be sure to use the appropriate directory)
- In this example: Directory – Desktops/800x480x24

- Upload the Thumbnail image and Background image in the same directory

- Restart the TFTP service on all nodes running TFTP
- Verify the background image is now selectable
