Upgrading the Firmware
Using the Auto-Resync Feature
The auto-resync feature on the IP phones allows an administrator to enable the
phone to be updated automatically once a day at a specific time in a 24-hour
period if the files on the server have changed. This feature works with TFTP, FTP,
HTTP, and HTTPS servers. An administrator can enable this feature using the
Aastra Web UI or using the configuration files (aastra.cfg and <mac>.cfg).
An Administrator can enable Auto-Resync using the configuration files or the
Aastra Web UI. In the configuration files you set the following parameters:
• auto resync mode - Determines whether the configuration server
automatically updates the phone’s configuration files only, the firmware only,
both the firmware and configuration files, or disables automatic updates. This
parameter works with TFTP, FTP, HTTP, and HTTPS servers.
• auto resync time - Sets the time of day in a 24-hour period for the IP phone to
be automatically updated. This parameter works with TFTP, FTP, HTTP and
HTTPS servers.
• auto resync max delay - Specifies the maximum time, in minutes, the phone
waits past the scheduled time before starting a checksync.
• auto resync days - Specifies the amount of days that the phone waits between
checksync operations.
In the Aastra Web UI, you can set the following parameters at the path Advanced
Settings->Configuration Server->Auto-Resync:
•Mode
• Time (24 hours)
• Maximum Delay
•Days
Setting the “auto resync max delay” (Maximum Delay) and “auto resync days”
(Days) parameters can greatly reduce the load placed on the configuration server
when downloading configurations.
Note: The automatic update feature works with both encrypted and plain
text configuration files.
