We have a number of VVX600 that we have nicely branded with Corporate Colour and Background images but we have recently purchased a number of CX5500 for our larger meeting room unfortuantly we are unable to get the background image to apply.
Our config looks like this
bg.color.CX5500.selection="2,1"
bg.color.CX5500.bm.1.name="CX5500_photo.jpg"
We you log in to the web interface i can see the images is uploaded and is viewable in the ui but on the device we still have the default background.
Looks like this is resolved in the 1.1.2.1 update although there is no mention of it in the release notes
