Upgrading the Firmware
8-6 41-001343-02 REV04 – 05.2014
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.
Reloading of Directory Files and Background Image During an Auto-Resync
During an auto-resync, the IP phones have the ability to initiate a comparison of its local directory files with those
located on the configuration server and automatically update the local directory files if changes are detected. For the
6739i, the background image is redownloaded and updated at this time as well.
If the auto-resync mode is set to” Configuration Files (1)” or “Both (3)”, either through the IP phone’s Web UI or configura-
tion files, when the phone reaches the configured auto-resync date/time, the phone will perform a comparison on the
directory files and trigger a reboot if differences are found. For the 6739i, in addition to the directory file comparison, the
background image will be redownloaded and updated. No reboot is necessary if the background image is the only file
that has changed.
If the auto-resync mode is set to “None (0)” or “Firmware Info (2)” and the phone reaches the configured auto-resync
date/time, the directory files will not be checked (and the background image for the 6739i will not be redown-
loaded/updated) .
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:
Irrespective of the auto-resync feature, if the phone receives a check-sync NOTIFY, the directory file comparison (and
background image update for the 6739i) will be performed and the applicable files will be automatically updated as
required.
Configuration Files
For specific parameters you can set in the configuration files for automatic update, see Appendix A, the section, “Configuration Server Settings” on
pageA-16.
Notes:
• If a user is accessing the Aastra Web UI, they are not informed of an auto-reboot.
• Any changes made using the Aastra 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 Aastra 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.
