I find that on-prem CUCM is still used fairly substantially.. :). The thumbnail needs to be PNG and 139x109 (not 159x109). I’d also double check the spelling and casing of the directory in TFTP; Desktops/800x400
Your images must be in PNG format and the dimensions of the full sized image must be within 800 pixels by 480 pixels. Thumbnail images are 139 pixels (width) by 109 pixels (height). https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cuipph/8800-series/english/adminguide/P881_BK_C136782F_00_cisco-ip-phone-8800_series/P881_BK_C136782F_00_cisco-ip-phone-8811-8841_chapter_01010.html#concept_325325E245AAC3BF76989A0D4E66A47F Sent from my iPhone On Sep 23, 2019, at 20:43, Dana Tong <dana.t...@yellit.com.au> wrote: Hi all, Not sure if anyone is still using on-prem CUCM much these days but am trying to update some 8811 background and am getting a “Wallpaper cannot be set. Incompatible image size”. My image and thumbnail are: 800 x 480 x 24 bit Thumbnails are: 159 x 109 x 24 which match the existing backgrounds. Although there is some documentation that says they need to be 139 x 109 for the Thumbnails. I would have thought the original included images would be okay? But they are not displaying either. Anyone done this and know for certain what they should be?
