I have a really strange issue. I´m deploying a new wallpaper on 8945 (SIP8941_8945.9-3-2-12) and 9971 (SIP9971.9-3-1-33) IP Phones. I´ve read that the firmware 9.3.1 for 9971 are more stable, so i already did the upgrade, but still the same. The wallpapers are available in the configuration and can be configured on both phones. Although when i press configure on 9971, the backgroung of wallpaper gets black, instead of white, which is the original colour, but when pressed view it shows correctly. I was wondering something about the file format, but the backgroung on 8945 are fine.
Can someone help me please, i don´t have a clue what´s happening?
CUCM version: 8.6
Thanks in advanced!!!!
