Thought I'd share since I have to deal with replacing quite a few 7912's. Cisco has decided to remove a few devices on CUCM 11.5. Most of them on the list we don't use with the exception of the 7912. If you have these phone? Get them replaced before you upgrade and switchover. Once you switch versions to 11.5, CUCM will block the phone from registering. What I find awkward, is you can start the adding of a new 7912 but once you attempt to finish the add, a message pops up and blocks the addition. Would of been nice if Cisco just removed the 7912's from the list of devices. Below is the list. You can also look up the release notes for 11.5 which details out the change.
