Cisco 8831 not registering with CUCM 10.5 (Internal Phone Error)

[shawn13872]

Running CUCM 10.5,  and just purchased a 8831 phone. The keypad is stuck with the Cisco Logo and CUCM shows the following " Inactive Load Failure Reason Internal Phone Error"

 Any ideas on how to resolve this issue:

New 8831 phones doesn't work with old firmware below 10.3 , you must have got a sticker on the phone box which says do not downgrade the firmware.

Try to force the load -SIP8831.10.3-ISR2-2 from phone config page and factory reset the phone.

Our system is 11.5.1.11900-26

do we still need to install cmterm-8831-sip.9-3-3-TO-10-3-1-v2.cop.sgn?

Hi Darin,

Yes, it still need to be installed as it is a phone intermediate firmware upgrade.

It has nothing to do with the CUCM version you are on.
