Hi,

Last night we have upgraded our CUCM version from 11.5 to 12.5. After the upgrade we notice some of the phone keep registering / unregister. As per checked in the Phone it show error : 

[10:22:18pm 27/11/22] Error updating user locale
[10:22:19pm 27/11/22] Error updating network local

For the phone firmware we already uploaded in both subs & pub node.

Phone Model CP-8841

Was it a upgrade or migration ? 

check you inactive partition for locale installation, if there exit install the locale for version 12.5 and see if it solved your problem.. 

How frequent the phones unregister ?

Hi, Thank You for your reply. Right now all the IP Phone working well. We uploaded all the Firmware package into both Publisher & Subscriber node then the IP Phone can get valid Firmware after we upgrade the CUCM 12.5.
