Screensaver configuration for Mitel 485G phones

We recently migrated to RingEx from the cloud phone platform formerly known as Shoretel Sky and we have made the unwelcome discovery that the firmware that RingCentral upgrades us to shows us random pictures of architecture. For us, this is a big problem because we are architects and the work isn’t ours. It’s a bit like if you went into Nintendo’s offices and the phones were cycling between pictures of Crash Bandicoot, Sonic and Master Chief.

I’ve looked in the firmware and tried to find discussions online for how to change what is displayed in the screensaver and I haven’t yet turned up anything useful. I also emailed our rep, but he’s just emailed other people. There has to be a way, so any help finding that way would be appreciated.

So I have done some digging and apparently the 485G firmware is a variant of the Mitel 6900 firmware and I was able to turn up some documentation on that here:

It all centers around a Configuration File and a Configuration Server, none of which exist in any direct way with the implementation I’ve been given.

From similar queries in the past that I found someone had the idea that they should be able to upload files directory to the phones and replace the existing files there, but I haven’t seen anyone say they did it successfully and I’m not sure if the options to do that exist in the current firmware version.

But at least it should be theoretically possible from what I’ve found, but it could be potentially a very annoying process. I’m surprised at the total lack of branding ability in the platform. The ShoreTel Sky platform had the ability to have logos (via the background picture) on the phones pushed out centrally and I was expecting our ‘upgrade’ to have more capabilities not less. Not even less, but for the moment our office is showing off our competitors work!
