5055 SIP Phone User Guide (Rev. A)

Upgrading the firmware using the SIP Phone Menu Interface

You upgrade the SIP Phone by downloading the new firmware from the appropriate TFTP server (the TFTP server is programmed with the Network Configuration).

CAUTION: During this procedure, DO NOT remove power from the SIP Phone while firmware is downloading or the phone is rebooting. This may result in severe damage to your SIP Phone.

1.To restart the phone, press the Menu, and 0 keys in sequence.

2.When the display shows “Booting…”, press and hold the 2 key on the keypad. This upgrades the boot firmware of the SIP Phone.

3.When “UPGRADE FIRMWARE?” appears, release the key and press the YES softkey.

4.The phone now gives you the option of using the displayed TFTP IP address (this IP address is set in the Network Configuration Page), or entering one of your own.

5.Press the key. The firmware starts downloading.

6.When the new firmware has finished downloading, the SIP Phone reboots. This process may take a minute or two. It’s complete when the display shows a time and date on the top line of the display (default display). In some cases, upgrade of the boot firmware will automatically trigger upgrade of the Main firmware. If you need to force the upgrade of the Main firmware, press the Menu, and 0 keys in sequence, then hold the 1 key (the phone then requires you to select the TFTP IP address, and press the key). This process may take a minute or two, and is complete when the display shows a time and date on the top line of the display (default display).

7.In some cases it may be necessary to reset the settings of the SIP Phone to factory defaults (note: this procedure will erase all your settings then replace them by the factory defaults). To do this

Press the Menu key.

Press * on the keypad.

Press # on the keypad.

Press and hold the 3 key on the keypad until “USE FACTORY DEFAULTS?” is displayed.

Press the YES softkey. The settings are reset, and the phone reboots.

When the time and date are displayed, you must reprogram the SIP Phone or reload a saved configuration file (see Changing Passwords, Setting Up User Profiles, Creating/Modifying a SIP Account and Modifying the Network Configuration in this section). Saved configuration files do not restore passwords, so you will have to re-enter your passwords manually.
