/mcp• DisplayName defines the name of the custom ring for the associated PCM file that will display on the Ring Type menu of the Cisco Unified IP Phone. • FileName specifies the name of the PCM file for the custom ring to associate with DisplayName. The DisplayName and FileName fields must not exceed 25 characters. Tip The following example shows a Ringlist.xml file that defines two phone ring types: <CiscoIPPhoneRinglist> <Ring> <DisplayName>Analog Synth 1</DisplayName> <FileName>Analog1.raw</FileName> </Ring> <Ring> <DisplayName>Analog Synth 2</DisplayName> <FileName>Analog2.raw</FileName> </Ring> </CiscoIPPhoneRinglist> You must include the required DisplayName and FileName for each phone ring type. The Ringlist.xml file can include up to 50 ring types. Tip Custom Backgrounds You can also use the TFTP server to upload new custom background images to the phones in your network. Phone users can select the images that you upload as their phone backgrounds. You can configure your system so that phone users can select from an assortment of images or you can assign a specific background image for all phone. If you want your phone users to be able to customize their phone backgrounds, then you must prepare and upload the following files to the TFTP server whenever you upload new images: • Full-size background image—Refer to your phone documentation for image specifications, including the image size (in pixels) and color-type, for your phone model. • A thumbnail image—This is only required if you want your phone users to be able to choose their own background image. Refer to your phone documentation for the thumbnail image specifications • An edited List.xml file—This file contains a listing of the background images from which phone users can select. You must add your new images to this file. If you want to assign a specific image for all phones then you need to upload the main background image only. In addition, you also must update the Common Phone Profile to direct the phones to use the image that you assign.
