Introduction

This document describes the procedure to create a background image for a Cisco 7970 IP Phone in the Cisco CallManager Express environment.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco CallManager Express.

Components Used

The information in this document is based on Cisco CallManager Express Version 12.3(14)T2.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Create a Customized Background Image

Complete these steps to create a customized background image for a Cisco 7970 IP Phone on Cisco CallManager Express:

1. Use an image manipulation program of your choice to create two Portable Network Graphics (PNG) files for each image:

   • Full size image—320 pixels (width) by 212 pixels (height)

   • Thumbnail image—80 pixels (width) by 53 pixels (height)

   The size ratio of these two images is 4 to 1.

2. Use a text editor to edit the List.xml file.

   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—The uniform resource identifier (URI) that specifies where the phone obtains the thumbnail image that appears on the Background Images menu on a phone.

   • URL—The URI that specifies where the phone obtains the full size image.

   This example shows a List.xml file that defines one image. The required image and URL attributes must be included for each image. In this example, TN-velara.png is twenty-five percent of the original full size image of velara.png.

   <CiscoIPPhoneImageList>
   <ImageItem Image="TFTP:Desktops/320x212x12/TN-velara.png"
   URL="TFTP:Desktops/320x212x12/velara.png"/> 
   </CiscoIPPhoneImageList>

3. Place the new .png files and List.xml that you created in the tftp folder on the TFTP server.

   This is the folder name if you use the TFTP server that runs on Cisco CallManager:

   C:\Program Files\Cisco\TFTPPath

4. Use this command to move the List.xml and .png files to the Cisco CallManager Express Flash one-by-one:

   copy tftp flash:Desktops/320x212x12/

   Figure 1 demonstrates the transfer of List.xml from the TFTP server to the Cisco CallManager Express Flash:

   Figure 1—Transfer List.xml from the TFTP server to CallManager Express Flash

   

   After the loading process completes, the Desktops/320x212x12 directory on the Cisco CallManager Express Flash contains List.xml and all .png files as Figure 2 shows:

   Figure 2—Desktops/320x212x12 on the CallManager Express Flash

   

   Note: If the Desktops/320x212x12 directory is not found, you need to create a folder in that name using the mkdir command. Some flash file systems do not allow creating a directory with the mkdir command.

   CME-CUE#mkdir flash:Desktops/320x212x12
   

   Note: In that case you need to backup the flash content and format the flash using the format flash: command, and make a Class C Flash file system.

5. Add the appropriate tftp-server commands on the Cisco CallManager Express configuration to load List.xml and all .png files.

   Figure 3 shows List.xml, TN-velara.png, and velara.png:

   Figure 3—tftp-server Configuration

   

   Note: Use the debug tftp events command to find out which file the phone searches for when the backgound selection button is pressed on the IP phone.

6. Complete these steps to load a new background image on the Cisco 7970 IP Phone:

   1. Press Settings.

   2. Select User Preferences (choice 1).

   3. Select Background Images (choice 2).

   4. Download and display the reduced images as thumbnails.

   5. Select the image and press Save.

Delete a Background Image from the 7970 IP Phone

The background image is stored in the Flash memory of the IP phone. This cannot be deleted unless you perform a factory reset of the 7970 IP phone. Complete these steps in order to perform a factory reset of the IP phone. The phone must be on a network that supports DHCP.

1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.

2. While the phone powers up, and before the Speaker button flashes on and off, press #. Each line button flashes on and off in sequence.

3. Press 123456789*0#. You can press a key twice in a row, but if you press the keys out of sequence, the factory reset does not take place. Now the lights should change color from amber to red.

4. Press 1 in order to maintain the current network configuration settings for the phone when the phone resets.

The background image chosen by the user depends upon the images available in the TFTP folder. If you need to restrict the background images used by the user, remove the images from the TFTP folder.

Troubleshoot

Error: Selections Unavailable

When you try to change the background image in Settings > User Preferences > Background Images, the Selections Unavailable error message appears.

Solution

This issue can occur when the List.xml file is absent from the C:\Program Files\Cisco\TFTPPath\Desktops\320x212x12 folder on the TFTP server. Make sure the \Desktops\320x212x12 folder is present in the TFTP server and that the List.xml file is available under this directory.

Note: Make sure the TFTP server IP address configuration on the IP phone refers to the Cisco CallManager Express router.
