Cisco 7912 registering to CUCM 14

[rmeuchel]

Does anyone know if a Cisco 7912 will register on CUCM 14? I know it's deprecated in an older version of CUCM. However, will placing and receiving basic calls still work (although it would not have security updates, bug fixes, etc.)? Or does the 7912 model type simply not exist if you try to add it to CUCM 14?

Thanks!

Existing phone if you are upgrading to 14 will show rejected and you will see a message on the login page.

Problem / Symptom

If you are running any of these phone models that have been deprecated, after you upgrade and switch over to the new release, registration will be blocked on the phone. If the phone remains powered on, the phone will make repeated registration attempts, which will create unnecessary network traffic as well as a load on the Cisco CallManager service.
