8800 Background Images

Jacob Webb · ‎10-07-2015

I created a custom background for all my 8841 and 8851 devices with my company logo, but since the background is white, it is very hard to read the numbers at the top of the screen and the speed dials. Is there a way to change the text color or does anyone know the dimensions of these areas so I can shade the image to make the text readable?

Unfortunately no, you will need to adjust your image to either be different color or border in the area where text overlaps with background color.

Jeepers - very little clear instruction on this - I have actually completed and 'Proofed' below for 8841 and 8851 on CUCM 11.5.1

Here is the simple version...

You will need two copies of every wallpaper - one for the wallpaper itself and one for a thumbnail

The File Parameters are ..
pixels='800x480', ColourDepth='24bit' - name it 'WallpaperA.png'
pixels='139x109', ColourDepth='24bit' - name it 'TN-WallpaperA.png' (annoyingly these arent a clean ratio of each other)

NB - Right-click the file in file explorer, then Properties, Details, Image details and confirm the colour depth and pixels

Now you need to create an XML to tie this data together. First reference is the Thumbnail, second to the wallpaper, like

Save this as List.xml (notice Big L)

So now you have

WallpaperA.png
TN-WallpaperA.png
List.xml

Goto your TFTP Server, eg https:///<ip of CallManager>/cmplatform/ - and upload the files above to folder Desktops/800x480x24 (notice big D and its 480 NOT 400)

Now restart the TFTP Service -
eg goto - https://<ip of CallManager>/ccmservice/ - Tools / ControlCentre - feature Service / CmServices / Cisco TFTP Select and Restart

Now see if the file is good

http://<ip of tftp server>:6970/Desktops/800x480x24/WallpaperA.png

Of Course once you are confortable with this you can expand the selection easily by updating your XML file to..

Then you would be uploading 9 files to the folder - Desktops/800x480x24

WallpaperA.png
TN-WallpaperA.png
WallpaperB.png
TN-WallpaperB.png
WallpaperC.png
TN-WallpaperC.png
WallpaperD.png
TN-WallpaperD.png
List.xml

If that makes sense

Easy Peasy !

Most common faults reasons for not working are...
Image issues - try not to use MSPaint to create the file - the colour depth needs to be right - double Check the file details or open with Gimp to check and ensure format good.
XML Issues - List.xml is not correct - careful when using notepad or MSWord - needs to be a standard XML File - browse to http://<ip of tftp server>:6970/Desktops/800x480x24/List.xml to ensure its a valid XML File
TFTP Issues - ensure of Restart TFTP service and reset the phone, are you happy the phone is pointing at the TFTP server in question?
