I am having a difficult time getting wallpaper to show up on the 8941 phones. I have a 8961 with the exact same setup in terms of tftp server. The 8961 shows all the wallpaper just fine but the 8941 does not. According to Cisco documentation, they both use the 640x480x24 and 123x111 size png files. Can anyone tell me why the 8941 will not show the wallpaper?
