Procedure
Step 1
Create a PCM file for each custom ring (one ring per file). Ensure the PCM files comply with the format
guidelines that are listed in
PCM File Requirements for Custom Ring Types, on page 213
.
Step 2
Upload the new PCM files that you created to the Cisco TFTP server for each Cisco Unified Communications
Manager in your cluster. For more information, see the
“
Software Upgrades
”
chapter in
Cisco Unified
Communications Operating System Administration Guide
.
Step 3
Use a text editor to edit the Ringlist.xml file. See
Ringlist.xml File Format Requirements, on page 212
for
information about how to format this file and for a sample Ringlist.xml file.
Step 4
Save your modifications and close the Ringlist.xml file.
Step 5
To cache the new Ringlist.xml file, stop and start the TFTP service by using Cisco Unified Serviceability or
disable and reenable the
“
Enable Caching of Constant and Bin Files at Startup
”
TFTP service parameter (that
is found in the Advanced Service Parameters area.)
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
>
Preferences
>
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.
All file names are case sensitive. If you use list.xml for the file name, the phone will not apply your
changes.
Attention
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
Applications
>
Preferences
>
Wallpaper
option does not
display on the phone.
For more information, see the
“
Common Phone Profile Configuration
”
chapter in the
Cisco Unified
Communications Manager Administration Guide
.
List.xml File Format Requirements
The List.xml file defines an XML object that contains a list of background images. The List.xml file is stored
in the following subdirectory on the TFTP server:
