CER license count 10.x

[Kurt Warner]

I got an alert that CER was oversubscribed by 7 licenses. I promptly removed 8 test phones from systems and then forced a "sync now" in Cisco Prime license manager.  The number actually grew by 2 ??  I am the only person who adds/removes phones.  How are these calculated and how can I free up some licenses??

It is based on tracked phones and manual phones. So if someone has added manual phones that would do it , or exclude some IP range that’s registering to your UCM that you don’t want to deal with.

It loads all registered devices via SNMP and goes from there plus manual devices.
