Firmware Upgrade
There are two methods of firmware upgrade:
l
Manually, from the local system for a single phone via web user interface.
l
Automatically, from the provisioning server for a mass of phones.
Note
We recommend that IP phones running the latest firmware should not be downgraded to an earlier firmware version. The
new firmware is compatible with old configuration parameters, but not vice versa.
