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 Mitel Web UI or using the configuration files (aas-
tra.cfg, <model>.cfg, and <mac>.cfg).
An Administrator can enable Auto-Resync using the configuration files or the Mitel 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 parame-
ter 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 Mitel 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.
Enabling Auto-Resync Using the Configuration Files
Use the following procedure to configure automatic updates of the IP phone firmware, configuration files, or both.
Note:
The automatic update feature works with both encrypted and plain text configuration files.
Configuration Files
For specific parameters you can set in the configuration files for automatic update, see Appendix A, the section, “Configuration Server Settings” on
pageA-15.
Notes:
• If a user is accessing the Mitel Web UI, they are not informed of an auto-reboot.
• Any changes made using the Mitel Web UI or the IP phone UI are not overwritten by an auto-resync update. Auto-
resync affects the configuration files only. However, the settings in the Mitel Web UI take precedence over the IP
phone UI and the configuration files.
• If the IP phone is in use (not idle) at the time of the resync check, the reboot occurs when the phone becomes idle.
• The resync time is based on the local time of the IP phone.
• The automatic update feature works with both encrypted and plain text configuration files.
