There is not option available as of now...but
we do have an item on our roadmap to allow phone designer to modify the background of the
7915/7916 as well but it is not currently committed for a release.
I just wanted to bump this since it has been a few years. Do we still have no way to change the background color of the 7916? That blue is just ugly...
A previous Cisco poster indicated this was on the roadmap back in 2009. Fast forward 36 months....Is the BU looking at adding this feature or not?
