Hi,

Those phones probably cannot connect successfully to tftp server to download the image list and the backgrounds.

This could also be caused by an error of secure connection to the TFTP. I suggest to delete security settings of those phones through Admin Settings Menu than Erase Security Settings.

HTH

Hi Ahmed,

Make sure that connectivity exists between those IP Phones and CUCM. 

You can also download tftp logs through Real time monitoring tool and see if you can see requests coming from those Ip Phones.

If you can, please post RTMT TFTP logs here so we can give a look

Thanks a lot
