You need to look for firmware downloads on the support page of your
admin panel. Then download the firmware and install it manually. I just
did this at a small branch that has a 90G. On Monday, when people return
to work, we'll see what happens... Go...
I'm still waiting too... I'm having a lot of problems with the
instability of the 90G (poor call quality, unstable Wi-Fi, dropouts). I
won't fall for newly released hardware again... what a blunder.
