question

It appears as though we cannot persist custom background images on Polycom VVX 410 desk phones. We can upload a new image to the phone directly, but upon reboot, the phone reverts back to the default image. Is there a setting somewhere to allow it to be persisted between reboots. The RingCentral default background is quite bad (and makes the line/extension text incredibly difficult to read) and we'd like to "brand" our phones.
