I've been through many topics on the boards here concerning the background images on supported phones but I haven't seen this particular issue yet.
First off, I have a 7971G-GE desk phone and an IPC soft phone I am testing with. I modified an existing List.xml file to use three sample images (and thumnbnails) of the correct size and placed them in the correct directory according to this document:
I thought something was wrong with my .XML file or images until I tested from the IPC phone. It works on the softphone, but it is still giving me the message "Selections Unavailable" on the desk phone even though both should use the same directory on the CUCM TFTP server. Both devices are registered to the publisher. Any troubleshooting ideas?
Try to do a factory reset on your desk phone.
1. Unplug power from the phone
2. Press # key
3. Plug power while pressing # key
4. Wait untill phone buttons start flashing.
5. Press your phone digits 123456789*0#
Now your phone will start upgrading firmware and factory reset procedure. This may take 5 mins.
After completing it, try to change the background again
