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 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—95 pixels (width) X 34 pixels (height).
• Thumbnail image—23 pixels (width) X 8 pixels (height).
• Color palette—For best results, use the monochrome or black/white setting
when you create a PNG file.
Configuring a Custom Background Image
To configure custom background images for the Cisco Unified IP Phone, follow
these steps:
Procedure
Step 1 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 Images” section on page 6-6.
Step 2 Upload the new PNG files that you created to the following folder to the TFTP
server for each Cisco
Unified CallManager in the cluster. For more information,
see the “Software Upgrades” chapter in the Cisco
IP Telephony Platform
Administration Guide.
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 CallManager.
