Yealink Settings Get Overwritten by Zoom (?)

[factor110]

Hello there. We have Yealink T46S desk phones (all on current firmware) with the label, display name, and wallpaper set up via Yealink's web interface. Seemingly randomly, the label and display name will go back to what it is named in Zoom's settings and the wallpaper will revert back to default (which is nothing). It seems to happen with all the phones, but not at the same time. And it happens repeatedly. I will change the settings back and within a few days, they revert again. I reached out to Yealink and they think it is caused by Zoom auto firmware update. Does this sound correct - would that cause these settings to revert back? I would prefer not to disable it updating the firmware. Or does anyone know why else this might be happening?

Incidentally, I have the same custom background image (i.e. wallpaper) set up in Zoom > General Settings > Background Image, but that does not seem to carry through to the phone for some reason.

Thanks for any insight!
