To create custom conference phone rings for the conference 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, on page 105 section.
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 Cisco Unified Communications Operating System
Administration Guide, “Software Upgrades” chapter.
Step 3
Use a text editor to edit the Ringlist-wb.xml file. See the Ringlist-wb.xml file format requirements, on
page 104 section for information about how to format this file and for a sample Ringlist-wb.xml file.
Step 4
Save your modifications and close the Ringlist-wb.xml file.
Step 5
Cache the new Ringlist-wb.xml file:
a) Log on to Cisco Unified Communications Manager Administration.
b) From the Navigation drop-down list at the top right of the window, select Cisco Unified Serviceability,
and then press Go.
c) Choose Tools > Control Center - Feature Services.
d) In the CM Services area, locate, stop, and start the Cisco TFTP service.
