Custom Wallpaper Picture Limitations

Adjusting the wallpaper is only compatible with all color-screen phones and expansion modules.

Some smaller or larger pictures may be scaled to fit the screen. The wallpaper picture format must meet the following requirements:

Adding Custom Wallpaper Via URL Download

A Yealink device can download an image from a URL to the phone inventory and then display it as the active wallpaper using two different configuration parameters:

wallpaper_upload.url

This first parameter sets the URL that the phone will use to download the file. The value of this parameter is limited to 511 characters. 

Depending on if you're going to display this downloaded photo on the phone, expansion module, or both determines the use of the second configuration parameter(s): 

phone_setting.backgrounds
expansion_module.backgrounds

This configuration chooses the photo from the available inventory of photos on the phone to display as the wallpaper. The value of these parameters must be the exact name and file extension of the downloaded image.

Example use:

wallpaper_upload.url="https://i.imgur.com/zpJwMzd.jpg"
phone_setting.backgrounds="zpJwMzd.jpg"

In this case the phone would download the image zpJwMzd.jpg hosted at https://i.imgur.com/zpJwMzd.jpg and then display it on the phone.
