How to find and download list of SEP<MAC>.cnf.xml files from CUCM?

I am sure most of you are aware of Cisco IP Phone Registration Process, however i am going to post the Registration process in next post. As of now let’s see how to download XMLDefault.cnf.xml or SEP<MAC>.cnf.xml from Cisco Unified Communications Manager TFTP?

When you connect a new IP Phone which was never registered to Cisco Unified Communications Manager and auto-registration is enabled, it will use a file called as  XMLDefault.cnf.xml. Cisco IP phones  will download this XML file via TFTP, will learn the IP address and Port to send SCCP (Skinny Client Control Protocol) messages when attempting to register. The Cisco IP Phone will also learn firmware version that is required to function properly with the Cisco Unified Communications.

If you are connecting a Cisco IP Phone that was already registered in CUCM, then the phone contacts the TFTP server and requests TFTP Server to provide IP Phone’s configuration file. This time it will not look for XMLDefault.cnf.xml file. Since the IP Phone was already configured and registered earlier, it will look for the config file which is based on the unique Mac-Address. The file will be in the format SEP<mac_address>.cnf.xml which is created by CUCM and uploaded to TFTP Server whenever the administrator creates or modifies the Cisco IP Phone.

How to download the file “SEP<mac_address>.cnf.xml” from Cisco Unified Communications Manager?

    Rarely have I ever needed to do this, and generally it’s just to confirm that a setting is being deployed properly on a phone that didn’t seem to work properly.

    So my question is, what prompted this post and what other types of scenario’s do people need to download the config files?
