Hello,
Just in case you need to download the current List.xml you can use the command below from the CUCM TFTP CLI.
In order to keep all images that all phones currently have you need to download the List.xml from the CUCM TFTP. You can go to the CLI of the TFTP server and run the command below.
file view activelog cm/tftpdata/Desktops/800x480x24/List.xml
Command example:
admin:file view activelog cm/tftpdata/Desktops/800x480x24/List.xml
<CiscoIPPhoneImageList>
<ImageItem Image="TFTP:Desktops/800x480x24/CiscoTH.png" URL="TFTP:Desktops/800x480x24/CiscoFull.png"/>
</CiscoIPPhoneImageList>
end of the file reached
options: q=quit, n=next, p=prev, b=begin, e=end (lines 1 - 3 of 3) :
admin:
Once you have the output you can copy/paste past the line below to add the new blank images to CUCM TFTP.
<CiscoIPPhoneImageList>
<ImageItem Image="TFTP:Desktops/800x480x24/BlankimageTH.png" URL="TFTP:Desktops/800x480x24/BlankimageFull.png"/>
<ImageItem Image="TFTP:Desktops/800x480x24/CiscoTH.png" URL="TFTP:Desktops/800x480x24/CiscoFull.png"/>
</CiscoIPPhoneImageList>
Now you can save and you can also change from .txt to .xml.
At this point you can upload the List.xml and the images TH and Full to ALL TFTP servers running active in your environment.
In order to find out which servers are running the TFTP service you can go to Cisco Unified Serviceability > Tools > Feature Services > Check if Cisco TFTP is running.
Remember to make the changes effective you must restart the Cisco TFTP service following the steps Cisco Unified Serviceability > Tools > Feature Services > Check if Cisco TFTP > Restart (steps must be done to all TFTP servers running)

Once you have done the steps above, please see below. This information is for you to make a default background image in the IP Phones.
On 8800 phones there is an option to make the a image set as default on all phones, by doing this it allow us to still keep all the current images in case other users have it other wall papers for use.

Background Image: Specifies the default wallpaper file. When a default wallpaper is set, the user can't change the phone wallpaper.
Go to Background Image > Paste Desktops/800x480x24/CiscoFull.png
Note. This feature applies to certain phones only.
Now that all images are up you can set up the blank image by default on all phones. In order to do this bulk you must follow the steps below.
Go to: Cisco Unified CM Administration > Bulk Administration > Phones > Update Phones > Filter by Phone Type > Next > Go to Background Image > Paste Desktops/800x480x24/CiscoFull.png > Run Immediately. This will take you to Job Scheduler and the job should successfully complete for all phones.
Please make sure you have a maintenance window for these phones for about 10 minutes since this step re-registers the phone as when you hit on Run immediately it resets all phones selected.
When the user checks the phone the default image will be the Blank you uploaded, however since we did not remove the rest of the images from the List.xml all phones will have access to all images, but again the default image will be set to blank.
Note. Attached I am leaving the blank images I used in my lab, in case you need them.
Thank you,
