Upgrading the Firmware
The IP phone uses a TFTP, FTP, or HTTP server (depending on the protocol
configured on the IP phone) to download configuration files and firmware.
The configuration server should be ready and be able to accept connections. For
information on setting up the configuration server, see Chapter 1, the section,
“Configuration Server Requirement” on page1-20.
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 configuration files or the Aastra Web UI).

Manual Firmware Update (TFTP only)

Use the following procedure to activate a firmware download using TFTP.
Warning: Do not reset or turn off the phone until the download is
complete.
Note: This procedure allows you to download the <phone model.st> file
from a TFTP server even if your phone is configured to use HTTP or FTP.
