Cisco: 'UCM down, features disabled'
I came across a problem where a Cisco IP phone would slightly more than occasionally find itself unregistered with the CUCM. Below is what I would see:
Interesting problem for sure. What I found was there was this wireless print server attached to the phone in the PC port. Somehow, of which Im not sure at the moment, it would cause this phone to unregister with CUCM. When I took this little wireless print server off, all worked normal again without problem. I should have taken a picture of the wireless print server. Oh well.
