Add a Custom Background Image to an Edge IP 9840C Phone

The Edge IP 9840C phone has a 4.3-inch full-color graphic LCD that can display a custom background image such as a company image or logo. 

1. Make sure the image meets required specifications:
   Image Specifications: 480x272 BMP file
   Bit Depth: 24 bit
   Color Space Information: No
2. Save the image file to the folder location \\C$\inetpub\wwwroot\VIP\ (see Transfer files to and from Wave IP).
    
3. Create a custom XML file (Example: PHONEIMAGE_custom.xml) to apply the image to a given phone. (see Custom Configuration Files for Edge IP 9800 Series Phone). It will contain the following XML:

   <?xml version="1.0" encoding="UTF-8"?>
   <Settings>
       <Pui>
           <Display>
               <BackgroundImage>http://xx.xx.xx.xx/VIP/FILE_NAME.bmp</BackgroundImage>
           </Display>
       </Pui>
   </Settings>
   
   Replace xx.xx.xx.xx with the IP address of the Wave IP, and FILE_NAME.bmp with the name of the custom image file you saved in step #2.

4. The custom XML file should also be placed in  \\C$\inetpub\wwwroot\VIP\ (see Transfer files to and from Wave IP).
    
5. Trigger Wave to recognize the changed files and send the updated configuration information to th affected phones. This can be done in one of two ways:
   1. Restart Wave. This will take the system out of service, but is the simplest way if a large number of custom files were edited.
   2. If you just need to adjust a single phone or make a change during operating hours, make a change to the user's settings in Global Admin (see Login to User/Group Management). This will cause Wave to update the user's settings including the custom background image change.
