I was inquiring if you had installed the COP file on *all* of your servers, and not just the publisher/TFTP server (as per the release notes for the COP file).
To determine the firmware on the phone: If the phone has never registered the phone's webpage may still be active, so give it a try. In a browser, bring up http://<ip.address.of.phone> and go to the "Device Information" link. The current firmware will be listed there under "Version" (not App Load or Boot Load).
If the webpage is not active (CUCM disables this by default), you should be able to look on the phone itself. Settings > Applications > and then some menuing getting you to Device Information. I couldn't find the specific menu structure in the admin guides so either Cisco didn't document it or (for whatever reason) Cisco is not making that information available on the phone.
Regardless, we need to watch the phone attempt to register in the TFTP trace file and the Cisco CallManager trace file. Please gather those two trace files for the period around the registration and post them and we can look and figure out what is wrong. If you don't know how to pull trace files use the instructions at the link below. It is specific about how to gather the CallManager trace files, also check the box for the "Cisco Tftp" service while you are at it:
