Firmware Upgrade
Automatic Update (auto-resync)
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,
and HTTP servers. An administrator can enable this feature using the Aastra Web
UI or using the configuration files (aastra.cfg and <mac>.cfg).
When configuring via the Aastra Web UI, the administrator sets the following
parameters:
Mode Time
The Mode parameter determines the type of update that the IP phone performs:
configuration file only, firmware only, or both.
The Time parameter sets the period of time for which the IP phone is
automatically updated.
When configuring via the configuration files, the following parameters must be
set:
• auto-resync mode
• auto-resync time
Note: The automatic update feature works with both encrypted and plain
text configuration files.
