Hi Burney,
Yes, it's just a copy
Customizing and Modifying Configuration Files
You can modify configuration files (for example, edit the xml files) and add customized files (for example, custom ring tones, call back tones, phone backgrounds) to the TFTP directory. You can modify files and add customized files to the TFTP directory in Cisco IPT Platform Administration, from the TFTP Server File Upload page. Refer to Cisco IP Telephony Platform Administration Guide for information about how to upload files to the TFTP folder on a Cisco Unified CallManager server.
You can obtain a copy of the Ringlist.xml and List.xml files from the system using the following admin command-line interface (CLI) "file" commands:
admin:file
file list*
file view*
file search*
file get*
file dump*
file tail*
file delete*
