Is there anyway for us to upload the background image and xml file into CM8, and configure the URL in order for ip phone to have the specific background/wallpaper when first bootup

I had just deploy a CM8 and I found that when I have a internal call from extension to extension, the caller hear a short "du" tonewhen the call is offhook. Anyway to disable this tone?
