Configuring a Custom Phone Ring
To create custom phone rings for the Cisco Unified IP Phone, follow these steps:
Procedure
Step 1 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.
Step 2 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 the Cisco Unified Communications
Platform 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 Save your modifications and close the Ringlist.xml file.
Step 5 To cache the new Ringlist.xml file, stop and start the TFTP service by using
Cisco Unified Communications Manager 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).
