I’ve been working with the Cisco 8800 3PCC series phones lately, particularily the 8841 and the 8851. I didn’t realize when I had initially bought enterprise versions of these phones that the 3PCC version was basically (somewhat simplified) the Cisco SPA phone config on a newer model phone. I have been working with the Cisco SPA phones since 2012.
Since there is no 8800 series entries in Endpoint Manager, what I had to do is a workaround.
If you watch what files an 8800 phone looks for from the TFTP server on boot, it first looks for a file (8851 example) called 8851-3PCC.xml then a file called Cisco/CP-8851-3PCC/MAC.cfg
What I did was take one of the spa502.cfg files that Endpoint Manager creates in the tftpboot directory when the Cisco brand is installed and change the name to 8851-3PCC.xml. This tells the phone that it needs to look for a file called spaMAC.xml in the tftpboot folder, which is the file that Endpoint Manager creates when you provision a Cisco SPA phone.
After you add the Cisco brand to Endpoint Maanger, pick a model of Cisco SPA phone in endpoint manager that you aren’t using and edit the basefile according to what’s below. I picked the Cisco SPA508. When I provision the 8800 phones in endpoint manager now I have to choose SPA508 as the model.
Start from an unedited Cisco basefile in Endpoint Manager. For reference, I used Endpoint Manager 22.214.171.124.
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 8800 series.

Delete all the speed dial entries to allow users to set speed dials without having them overwritten.
Add these entries:
<Phone_Background ua=“na”>Download Picture</Phone_Background>
<XML_Directory_Service_URL group=“Phone/XML Service”>http://destination/phonebook/pbmenu.xml</XML_Directory_Service_URL>
<XML_Directory_Service_Name group=“Phone/XML Service”>FNG Directory</XML_Directory_Service_Name>
<Back_Light_Timer ua=“rw”>Always On</Back_Light_Timer>
Let me know if you have any changes to suggest, or a better way altogether to do this.
