so, access the tool’s Network Configuration page (see The Web Configuration Tool on
page 7).
Upgrade the Phone’s Firmware
The phone uses TFTP to download firmware from a TFTP server, or HTTP to download
firmware from the HTTP server. You can use either the phone or the Web Configuration Tool
(see The Web Configuration Tool on page 7) to perform a firmware upgrade. If you use the
Web Configuration Tool, access the tool’s Firmware Update page.
If you use the Web Configuration Tool, the phone’s original configuration is preserved;
therefore, the phone will function as it did prior to upgrade, without the need to reconfigure
settings.
If you use the options available on the phone, previous configurations may not be saved and
restored; therefore, you may have to manually reload a previously saved configuration file or
manually reconfigure phone parameters.

To view the current firmware version:
1. Press Superkey.
2. Press the Line 2 key. Both the main and boot firmware versions appear on the display.
3. Press Superkey to return to the default display.
Note: You also view firmware versions on the Web Configuration Tool home page (see The
Web Configuration Tool on page 7).
