Estimated reading: 2 minutes

Many companies wish to customize their phones with a wallpaper reflecting their visual identity. Thanks to PBXware, it is possible to push provisioning variables to the phones, thus making it easier to change the wallpaper.

The wallpaper image format must meet the following requirements:

Phone template	Format	Resolution
D713, D735, D765	.png	320×240
D375, D385, D785, D812, D815W	.png	480×272
D717	.png	426×240
D862, D865	.png	1280×720

TIP

Use an online image resizing tool to obtain the correct resolution, for example: https://www.img2go.com/fr/redimensionner-image

Host an image

To allow the image to be retrieved via an accessible URL, it is recommended to host your image on a platform like imgur.com

This will let you easily obtain the photo's URL in order to use it for provisioning.

Upload your image as follows:

Right-click on the image and then click the option Copy the image address.

Keep this link in your clipboard for the next step.

Edit the UAD

Go to PBXware, in your tenant, to the Settings > UAD section > Select your phone to provision:

Navigate to the bottom of the page to access General user agent auto-provisioning template :

Then copy and paste the following code, adjusting the URL of your image:

wallpaper_upload.url=https://i.imgur.com/votreimage.png phone_setting.backgrounds=votreimage.png

Here is the expected result:

Restart the phone remotely in Monitor > Check the phone > Force reboot :

TIP

You can restart several phones at the same time.
