CUCM v11 Cisco 8845 Device "Unable to obtain additional wallpapers from server"

[Georgios Sotiropoulos (OLD)]

Hello Community,

I have tried to upload some costum images to CUCM, while updating the List.xml in order to change the Wallpaper, mainly on Cisco 8845, however I receive the error on the display "Unable to obtain additional wallpapers from server".

I am bit worried if I use the correct dimensions for the images, as well as if the List.xml has the correct format.

First of all, you may see at the attachement List that there are 2 List.xml (is this right)?

Then, on the attachement "images" you may see the 2 new images that I have uploaded to CUCM.

Last but not least, I attach the 2 List.xml files that are included on the CUCM (as these are shown on my web-browser)

It would be great if someone could assist on the above,

Many thanks in advance!

Depending on phone model, you'll have a different directory and a different List.xml for each one

Hello Jaime,

Based on your experience, do you think that the List.xml files that I have attached are on a wrong format?

thanks,

Additionally, when I check the status messages of the phone I notice the error :

"[17:35:43 23/02/17] File not found : Desktops/800x480x24/List.xml"

Please also check attached "status_messages.png"

Any help is much appreciated.

Have you uploaded the files to ALL your TFTP servers?

Make sure there are no ITL issues.

[Georgios Sotiropoulos (OLD)]

Actually, currently there is only one TFTP, below are the full error messages on the phone

[17:22:13 24/02/17] Unknown reason:101

	[17:22:44 24/02/17] File not found : Desktops/800x480x24/List.xml

Moreover, when I ssh on the CUCM by show itl I see that the "The ITL file was verified successfully"

Do you think "Trust list update failed" may be the case?

[Jaime Valencia · Accepted solution]

Try deleting the certs from your phone and see if then it works.

[Georgios Sotiropoulos (OLD)]

There is no ITL signature on the device, if this is what you mean.

Is there an easy way to delete the CTL from the phone, or just factory reset?

[Georgios Sotiropoulos (OLD)]

Hi!

I have factory reset the device to download again the ITL file and now I am able to check the option on choosing the Wallpaper file.

However I get the error now "wallpaper cannot be set due to a problem loading the image"...

Hi Georgois

Please check if you are facing any of these issues

Example List.xml from Administration guide is wrong, it should be:

The main issue was that the phones had to be reset and make sure that the correct ITL file is in place.

Jaime thanks once more for your hints,
