How to Configure Custom Background Image for the Display on Voice Devices

The following are steps to set a custom background on supported voice devices from a customer HTTP server.

Supported Devices:

  • Poly CCX (portrait 720 x 1208, landscape 1024 x 600)
  • Poly Trio 8500 (720 x 1208)
  • Poly Trio 8800 (720 x 1208)
  • Poly Trio C60 (720 x 1208)
  • Poly VVX
    Screen size by phone:

    • VVX 300 and 400 series 220 × 108 pixels

    • VVX 500 series screens are 320 × 240

    • VVX 600 series screens are 480 × 272

    • VVX 1500 screens are 800 x 480

  1. Add the background image to desired path in your HTTP server.

  2. Update adequate policy with all the devices that share this background as explained below.

    bg.background.enabled = 1
    bg.color.selection = 2,1
    bg.color.bm.x.name = Full url of the background image file as in step 1
    bg.color.bm.x.em.name = Full URL of the background image file as in step 1
    Note: Optional parameter to be used if you want to configure background image to connected color expansion modules.

Example:

bg.background.enabled = 1  
bg.color.selection = 2,1  
bg.color.bm.1.name = http://<myhttpserver>/<mypath>/<backgroundfilename>  
bg.color.bm.1.em.name = http://<myhttpserver>/<mypath>/<em_backgroundfilename>

Notes:

  1. Poly phones support .bmp, .jpeg, .jfif, .jpg, .jpe, and .png image file formats; progressive/multi-scan JPEG images are not supported.
  2. The parameter bg.color.bm.x.name and bg.color.bm.x.em.name must have the exact name of the background image file as in step 1, or the phone will not be able to download the file from RPRM.
