Cisco 8821

Custom Phone Rings
The phone ships with three ring tones that are implemented in hardware: Sunshine, Chirp, Chirp1.
Cisco Unified Communications Manager also provides a default set of additional phone ring sounds that are
implemented in software as pulse code modulation (PCM) files. The PCM files, along with an XML file
(named Ringlist-wb.xml) that describes the ring list options that are available at your site, exist in the TFTP
directory on each Cisco Unified Communications Manager server.
All file names are case sensitive. If you use ringlist-wb.xml for the file name, the phone will not apply
your changes.
Attention
For more information, see the documentation for your particular Cisco Unified Communications Manager
release.
Set Up Custom Phone Rings
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 Custom Ring File Formats, on page 60.
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 documentation for your particular Cisco Unified
Communications Manager release.
Step 3
Use a text editor to edit the Ringlist-wb.xml file. See Custom Ring File Formats, on page 60 for information
about how to format this file and for a sample Ringlist.xml file.
Step 4
Save your modifications and close the Ringlist-wb.xml file.
Step 5
To cache the new Ringlist-wb.xml file, stop and start the TFTP service by using Cisco Unified Serviceability
or disable and reenable the “Enable Caching of Constant and Bin Files at Startup” TFTP service parameter,
located in the Advanced Service Parameters area.
Custom Ring File Formats
The Ringlist.xml file defines an XML object that contains a list of phone ring types. This file includes up to
50 ring types. Each ring type contains a pointer to the PCM file that is used for that ring type and the text that
appears on the Ring Type menu on a phone for that ring. The Cisco TFTP server for each Cisco Unified
Communications Manager contains this file.
The CiscoIPPhoneRinglist XML object uses the following simple tag set to describe the information:
<CiscoIPPhoneRingList>
<Ring>
<DisplayName/>
<FileName/>
