Allow and Configure Firmware Updates
The firmware updates can be allowed at specified intervals. Updated firmware is
sent from a server to the phone by using a TFTP or HTTP. Security is less of an
issue with a firmware upgrade, because firmware does not contain personal
information.
To configure a firmware update:
Click Admin Login > advanced > Voice > Provisioning.
Under Firmware Upgrade in the Upgrade Enable field, choose yes.
Enter the parameters defined in the table:
Parameter
Upgrade Enable
Upgrade Error Retry
Delay
Downgrade Rev Limit
