Grandstream GXP2130/40/60 Background Provisioning

[Michael Menor]

I know GS (Grandstream) phones are not very well supported in 3CX, but I was wondering if anyone has information on how to provision the logo (background) for the GXP2130, 2140, and 2160's. I checked the logo provisioning directory and found a few XML files labeled "gxp2XXX_screen" and "idle_screen.xml.gxpXXXX"

Any help would be greatly appreciated!
