Customizing and Modifying Configuration Files
You can modify configuration files (for example, edit the xml files) and add customized files (for
example, custom ring tones, call back tones, phone backgrounds) to the TFTP directory. You can modify
files and add customized files to the TFTP directory in Cisco Unified Communications Operating
System Administration, from the TFTP Server File Upload window. Refer to Cisco Unified
Communications Operating System Administration Guide for information about how to upload files to
the TFTP folder on a Cisco Unified Communications Manager server.
You can obtain a copy of the Ringlist.xml and List.xml files from the system by using the following
admin command-line interface (CLI) “file” commands:
•

Creating Custom Background Images
PCM File Requirements for Custom Ring Types
The PCM files for the rings must meet the following requirements for proper playback on
Cisco Unified IP Phones:
•
•
•
•
•
•
•
•
•
Raw PCM (no header)
8000 samples per second
8 bits per sample
uLaw compression
Maximum ring size—16080 samples
Minimum ring size—240 samples
Number of samples in the ring is evenly divisible by 240.
Ring starts and ends at the zero crossing.
To create PCM files for custom phone rings, you can use any standard audio editing package that
supports these file format requirements.
Configuring a Custom Phone Ring
To create custom phone rings for the Cisco Unified IP Phone 7975G, follow these steps:
Procedure
Step 1
Step 2
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 the “PCM File Requirements for Custom Ring Types” section on page 6-3.
Place 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 the “Ringlist.xml File Format Requirements” section
on page 6-2 for information about how to format this file and for a sample Ringlist.xml file.
Step 4
Step 5
Save your modifications and close the Ringlist.xml file.
To cache the new Ringlist.xml file, stop and start the TFTP service by using Cisco Unified
Serviceability or disable and re-enable the Enable Caching of Constant and Bin Files at Startup TFTP
service parameter (located in the Advanced Service Parameters).
Creating Custom Background Images
You can provide users with a choice of background images for the LCD screen on their phones. Users
can select a background image by choosing Settings > User Preferences > Background Images 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 used by the phone. 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.

Chapter 6 Customizing the Cisco Unified IP Phone
Creating Custom Background Images
The following sections describe how you can customize the background images that are available at your
site by creating your own PNG files and editing the List.xml file:
•
•
•
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:
/Desktops/320x216x16
Tip
If you are manually creating the directory structure and the List.xml file, you must ensure that the
directories and files can be accessed by the user\CCMService, which is used by the TFTP service.
For more information, see the “Cisco TFTP” chapter in Cisco Unified Communications Manager System
Guide and the “Software Upgrades” chapter in Cisco Unified Communications Operating System
Administration Guide.
The List.xml file can include up to 50 background images. The images are in the order that they appear
in the Background Images menu on the phone. For each image, the List.xml file contains one element
type, called ImageItem. The ImageItem element includes these two attributes:
•
Image—Uniform resource identifier (URI) that specifies where the phone obtains the thumbnail
image that will appear on the Background Images menu on a Phone.
•
URL—URL that specifies where the phone obtains the full size image.
The following example shows a List.xml file that defines two images. The required Image and URL
attributes must be included for each image. The TFTP URI that is shown in the example is the only
supported method for linking to full size and thumbnail images. HTTP URL support is not provided.
List.xml Example
<CiscoIPPhoneImageList>
<ImageItem Image=”TFTP:Desktops/320x216x16/TN-Fountain.png”
URL=”TFTP:Desktops/320x216x16/Fountain.png”/>
<ImageItem Image=”TFTP:Desktops/320x216x16/TN-FullMoon.png”
URL=”TFTP:Desktops/320x216x16/FullMoon.png”/>
</CiscoIPPhoneImageList>
The Cisco Unified IP Phone firmware includes a default background image. This image is not defined
in the List.xml file. The default image is always the first image that appears in the Background Images
menu on the phone.
PNG File Requirements for Custom Background Images
Each background image requires two PNG files:
•
•
Full size image—Version that appears on the phone.
Thumbnail image—Version that displays on the Background Images screen from which users can
select an image. Must be 25% of the size of the full size image.

Chapter 6 Customizing the Cisco Unified IP Phone
Creating Custom Background Images
Tip
Many graphics programs provide a feature that will resize a graphic. An easy way to create a thumbnail
image is to first create and save the full size image, then use the sizing feature in the graphics program
to create a version of that image that is 25% of the original size. Save the thumbnail version by using a
different name.
The PNG files for background images must meet the following requirements for proper display on the
Cisco Unified IP Phone:
•
•
•
Full size image—320 pixels (width) X 212 pixels (height).
Thumbnail image—80 pixels (width) X 53 pixels (height).
Color palette—Includes up to 16-bit color (65535 colors). You can use more than 16-bit color, but
the phone will reduce the color palette to 16-bit before displaying the image. For best results, reduce
the color palette of an image to 16-bit when you create a PNG file.
Tip
If you are using a graphics program that supports a posterize feature for specifying the number
of tonal levels per color channel, set the number of tonal levels per channel to 40 (40 red X 40
green X 40 blue = 64000 colors). This is as close as you can posterize to 65535 colors without
exceeding the maximum.
Configuring a Custom Background Image
To create custom background images for the Cisco Unified IP Phone, follow these steps:
Procedure
Step 1
Step 2
Create two PNG files for each image (a full size version and a thumbnail version). Ensure the PNG files
comply with the format guidelines that are listed in the “PNG File Requirements for Custom Background
Upload the new PNG files that you created to the following subdirectory in the TFTP server for the Cisco
Unified Communications Manager:
/Desktops/320x216x16
Note
The file name and subdirectory parameters are case sensitive. Be sure to use the forward slash
“/” when you specify the subdirectory path.
To upload the files, choose Software Upgrades > Upload TFTP Server File in Cisco Unified
Communications Operating System Administration. For more information, see the “Software Upgrades”
chapter in Cisco Unified Communications Operating System Administration Guide.
Note
If the folder does not exist, the folder gets created and the files get uploaded to the folder.
Step 3
You must also copy the customized images and files to the other TFTP servers that the phone may contact
to obtain these files.

Configuring Wideband Codec
Note
Cisco recommends that you also store backup copies of custom image files in another location.
You can use these backup copies if the customized files are overwritten when you upgrade
Cisco Unified Communications Manager.
Step 4
Step 5
Use a text editor to edit the List.xml file. See the “List.xml File Format Requirements” section on
page 6-4 for the location of this file, formatting requirements, and a sample file.
Save your modifications and close the List.xml file.
Note
When you upgrade Cisco Unified Communications Manager, a default List.xml file will replace
your customized List.xml file. After you customize the List.xml file, make a copy of the file and
store it in another location. After upgrading Cisco Unified Communications Manager, replace
the default List.xml file with your stored copy.
Step 6
To cache the new List.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
(located in the Advanced Service Parameters).
Configuring Wideband Codec
If Cisco Unified Communications Manager has been configured to use G.722 (G.722 is enabled by
default for the Cisco Unified IP Phone 7975G) and if the far endpoint supports G.722, the call connects
by using the G.722 codec in place of G.711. This situation occurs regardless of whether the user has
enabled a wideband headset or wideband handset, but if either the headset or handset is enabled, the user
may notice greater audio sensitivity during the call. Greater sensitivity means improved audio clarity but
also means that more background noise can be heard by the far endpoint—noise such as rustling papers
or nearby conversations. Even without a wideband headset or handset, some users may prefer the
additional sensitivity of G.722. Other users may be distracted by the additional sensitivity of G.722.
The following parameters in Cisco Unified Communications Manager Administration affect whether
wideband is supported for this Cisco Unified Communications Manager server or a specific phone:
•
Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
System > Enterprise Parameters. The default value of this enterprise parameter is True, which
means that all Cisco Unified IP Phone Series that are registered to this Cisco Unified
Communications Manager advertise G.722 to Cisco Unified Communications Manager. If each
endpoint in the attempted call supports G.722 in its capabilities set, Cisco Unified Communications
Manager chooses that codec for the call.
•
Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
Device > Phone. The default value for this product-specific parameter is the value that is specified
in the enterprise parameter. If you want to override this on a per-phone basis, choose Enabled or
Disabled in the Advertise G.722 Codec parameter on the Product Specific Configuration area of the
Phone Configuration window.

Configuring the Idle Display
Configuring the Idle Display
You can specify an idle display that appears on the phone LCD screen. The idle display is an XML
service that the phone invokes when the phone has been idle (not in use) for a designated period and no
feature menu is open.
XML services that can be used as idle displays include company logos, product pictures, and stock
quotes.
Configuring the idle display consists of these general steps.
1. Formatting an image for display on the phone.
2. Configure Cisco Unified Communications Manager to display the image on the phone.
For detailed instructions about creating and displaying the idle display, refer to Creating Idle URL
Graphics on Cisco Unified IP Phone at this URL:
In addition, you can refer to Cisco Unified Communications Manager Administration Guide or to Cisco
Unified Communications Manager Bulk Administration Guide for the following information:
•
Specifying the URL of the idle display XML service:
–
For a single phone—Idle field on the Cisco Unified Communications Manager Phone
Configuration window
–
For multiple phones simultaneously—URL Idle field on the Cisco Unified Communications
Manager Enterprise Parameters Configuration window, or the Idle field in the Bulk
Administration Tool (BAT)
•
Specifying the length of time that the phone is not used before the idle display XML service is
invoked:
–
For a single phone—Idle Timer field on the Cisco Unified Communications Manager Phone
Configuration window
–
For multiple phones simultaneously—URL Idle Time field on the
Cisco Unified Communications Manager Enterprise Parameters Configuration window, or the
Idle Timer field in the Bulk Administration Tool (BAT)
From a phone, you can see settings for the idle display XML service URL and the length of time that the
phone is not used before this service is invoked. To see these settings, choose Settings > Device
Configuration and scroll to the Idle URL and the Idle URL Time parameters.
Automatically Disabling the Cisco Unified IP Phone
Touchscreen
To conserve power and ensure the longevity of the LCD screen on the phone, you can set the LCD to
turn off when it is not needed.
You can configure settings in Cisco Unified Communications Manager Administration to turn off the
display at a designated time on some days and all day on other days. For example, you may choose to
turn off the display after business hours on weekdays and all day on Saturdays and Sundays.
When the display is off, the LCD screen is dark and disabled, and the Display button lights. You can take
any of these actions to turn on the display any time it is off:
•
Press any button on the phone.
