I was able to get a Cisco 6851 3PCC phone set up, and I thought I would share what I did in case anybody else is interested.
Start from an unedited Cisco basefile in Endpoint Manager. For reference, I used Endpoint Manager 14.0.2.188. You want to edit the basefile for the SPA504 model of phone, because it will set up the phone with the right number of lines. There are no entries in Endpoint Manager for any of the 3PCC phones, and I was told that no new Cisco phones would be added to it. That means that when you provision a 6851 3PCC phone, you will choose the SPA504 model in the provisioner.
I’m not sure if you’ll be able to cut and paste what’s below directly into Endpoint Manager. I had to backslash in front of the double underscore variable names. You’ll also need to download the firmware referenced in the Upgrade_Rule line below if you want to do the firmware upgrade. I was able to download it with my Cisco account, YMMV.

Delete these entries. These can be removed from the basefile rather than just clearing the entry in the option. These settings don’t exist on the 6851.

In addition to the basefile edits above, create a 6851-3PCC.xml file that you will put in the /tftpboot folder. I changed a spa504G.cfg file to make this. Don’t forget to modify the IP address below to the IP of your PBX.
