Administrator Options Firmware Update Features
The IP phone uses a TFTP, FTP, HTTP, or HTTPS server (depending on the
protocol configured on the IP phone) to download configuration files and
firmware.
You can download the firmware stored on the configuration server in one of three
ways:
• Manual firmware update using the Aastra Web UI (TFTP only).
• Manual update of firmware and configuration files (by restarting the phone
via the IP phone UI or the Aastra Web UI).
• Automatic update of firmware, configuration files, or both at a specific time
in a 24-hour period (via the Aastra Web UI or configuration files)
