Customizing the Cisco Unified IP Phone  
This chapter explains how you customize configuration files, phone ring sounds, background images,  
and idle display at your site. Ring sounds play when the phone receives a call. Background images  
appear on the phone screen. The idle display appears on the screen when the phone has not been used  
for a designated period.  
This chapter includes these topics:  
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 IP Telephony  
Platform 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 using the following admin  
command-line interface (CLI) “file” commands:  
admin:file  
file list*  
file view*  
file search*  
file get*  
file dump*  
file tail*  
file delete*

Configuring Wideband Codec  
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 packages that  
support these file format requirements.  
Configuring a Custom Phone Ring  
To create custom phone rings for the Cisco Unified IP Phone 7931G, 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  
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 an 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).  
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 7931G) and if the far endpoint supports G.722, the call connects  
using the G.722 codec in place of G.711. In this case, the user may notice greater audio sensitivity during  
the call. Greater sensitivity means improved audio clarity but also means that more background noise

Configuring the Idle Display  
can be heard by the far endpoint—noise such as rustling papers or nearby conversations. Even without  
a wideband headset, some users may prefer the additional sensitivity of G.722. Other users may be  
distracted by the additional sensitivity of G.722.  
Note  
The phone does not support wideband handset.  
The following parameters in Cisco Unified Communications Manager Administration affect whether  
wideband is supported for this Cisco Unified Communications Manager server and 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 Models 7931G, 7941G, 7941G-GE, 7961G, 7961G-GE,  
7970G, and 7971G-GE that are registered to this Cisco Unified Communications Manager will  
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 of this product-specific parameter is to use the value 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  
You can specify an idle display that appears on the phone 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 page, 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:

Automatically Disabling the Cisco Unified IP Phone Backlight  
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 page, 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, if the phone is registered with  
Cisco Unified Communications Manager, press the Application Menu button, then choose Settings >  
User Preferences > Audio Preferences and scroll to the Idle URL and the Idle URL Time parameters.  
By default, the Application Menu button is line button 24 (the top left line button).]  
Automatically Disabling the Cisco Unified IP Phone Backlight  
To conserve power and ensure the longevity of the phone screen backlight, you can set the backlight to  
turn off when it is not needed.  
You can configure settings in Cisco Unified Communications Manager Administration to turn off the  
backlight at a designated time on some days and all day on other days. For example, you may choose to  
turn off the backlight after business hours on weekdays and all day on Saturdays and Sundays.  
You can take any of these actions to turn on the backlight any time it is off:  
Press any button on the phone.  
The phone will take the action designated by that button in addition to turning on the backlight.  
Lift the handset.  
When you turn the backlight on, it remains on until the phone has remained idle for a designated length  
of time, then it turns off automatically.  
Table 6-1 explains the Cisco Unified Communications Manager Administration fields that control when  
the backlight turns on and off. You configure these fields in Cisco Unified Communications Manager  
Administration in the Product Specific Configuration page. (You access this page by choosing Device >  
Phone from Cisco Unified Communications Manager Administration.)  
You can view the backlight settings for a phone from the Power Save Configuration menu on the phone.  
For more information, see the “Power Save Configuration Menu” section on page 4-21.
