I have a Cisco CP-8831 conference phone and CUCM 9.1. I have added and applied the firmware and related files to CUCM cluster and the system does recognize 8831. I add the phone and the phone is receiving all needed TFTP, CTL information. Phone is coming up "phone not registered" also says "Error DB Config". Active load sip8831.9-3-3-3. Can someone point me in the right direction to get this going?
