I am trying to change the locale in IPPhones 7911 under CUCM 8.0.2.
There are several 7911 already in spanish but when i have tried to add new phones but it does not update the locale from english to spanish, those new phones are new.
The firmware installed in all phones is SCCP11.9-0-2SR1S, I have tried to change to 9-3-1 or 8-2-2 but always via web from IPPhones I see "error updating locale" and remain in english.
In cisco the firmware for version 7 is in .exe or .zip and CUCM does not recognise that extension and cannot to upgrade from OS,
Does anybody know how to change the locale? or why I receive this error?
