About this task
Devices must have the correct firmware version installed for enrollment. By default, if a device is not claimed, Device Enrollment Services upgrades it to the minimum required version. If a device is claimed, automatic upgrades are disabled for customer accounts by default. To enable firmware upgrades, see Enabling or disabling device firmware upgrades.
Note:
Some phone versions, such as version 1.5 of the Avaya J100 Series IP Phones, do not support automatic firmware upgrades. You must manually upgrade the Avaya J100 Series IP Phones to version 2.0 and reset to the factory default settings.
