The PCM files for the rings must meet the following requirements for proper playback on the phones:
• Raw PCM (no header)
• 8000 samples per second
• 8 bits per sample
• Mu-law compression
• Maximum ring size = 16080 samples
• Minimum ring size = 240 samples
• Number of samples in the ring = multiple of 240.
• Ring start and end at zero crossing.
To create PCM files for custom phone rings, use any standard audio editing package that supports these file
format requirements.
Custom Background Images
You can provide users with a choice of background images (or wallpaper) for the LCD screen on their phones.
Users can select a background image by choosing Applications > Settings > Wallpaper on the phone.
The image choices that users see come from PNG images and an XML file (called List.xml) that are stored
on the TFTP server that the phone uses. By storing your own PNG files and editing the XML file on the TFTP
server, you can designate the background images from which users can choose. In this way, you can provide
custom images, such as your company logo.
The dimensions for the PNG and List.xml images must be within 800x480x24.
Note
All file names are case sensitive. If you use list.xml for the file name, the phone will not apply your
Attention
changes.
You can disable the option for users to select a background image by unchecking the Enable End User Access
to Phone Background Image Setting check box from the Common Phone Profile Configuration window in
Cisco Unified Communications Manager Administration (Device > Device Settings > Common Phone
Profile). When this check box is unchecked, the wallpaper menu does not display on the phone.
