Updating Firmware
The firmware update process can be initiated from the handset, by sending a SIP
notify with a check-sync event to the gateway, or by scheduling a firmware update.
Handset initiated firmware updates
A firmware update can be initiated from the handset using
Settings

. In the firmware update menu select the desired firmware
version and language. Use the right and left navigation keys to switch between the

the

menu is pincode protected.
Automatic indication of new firmware
By sending a SIP notify with event check-sync to the management SIP UA the
gateway will update to the newest software available in the firmware update path on
the firmware update server.
The following configuration is needed for firmware update.
Initiating firmware update by schedule
By default the Aastra MBU 400 system searches for a new firmware once every 24
hours (with a random time-offset). If new firmware is found, the handset will prompt
the user for a system update. Firmware updates can be scheduled on the Aastra MBU
400 gateway in the following ways.
• Define a time [HH:MM] for the MBU to search for an update. This will cause the
system to search for new firmware update every day at the specified time.
• Define a polling period; this will cause the MBU to search for new software every
after each specified time interval (or polling period), and if new software is found
to update the system.
