Adding a background image to your Cisco desk phone

As an admin, you can add a background image to your desk phones directly from the Zoom web portal using a URL. You can upload the wallpaper to a TFTP, HTTP, or HTTPS server. The image should be in a .jpg or .png file. The preferred dimension for the file is 800x480 pixels, however, you can upload an image that is not the preferred dimension and it will be resized to fit the screen. You can review the list of supported device models.
