Could you please help me with a such problem.
I've uploaded png images on my CUCM TFTP server and can choose them from my desk phone menu.
I want to force all my phones(8941, 8845) to use my image, I don;t want to configure them one by one from the menu. And I can't do it.
I've configured Common phone profile with my image, checked/unchecked Enable End User Access to Phone Background Image Setting. I've tried to configure images also on the device page and it didn't work too.
What the problem it could be? Why I can choose image from the menu, but can't configured on device page or common phone profile?
