Upgrading the Firmware
To upgrade the firmware using the Web Configuration Tool:
• Access the Configuring Network Settings and Updating Firmware sections of the
Administrator's Web Configuration Tool.
Note: The phone will compare its existing firmware with the firmware on the server. If both
versions are identical, the phone will not perform the upgrade procedure.
CAUTION: DO NOT remove power from the phone while the phone is upgrading flash memory.
This may result in severe damage to your phone.
Troubleshooting Tip: If your phone displays "SIP MAIN NOT FOUND", it is likely that your
system has experienced a power failure. The SIP Phone Boot firmware "borrows" Flash sectors
from the SIP Main area during firmware installation. At the end of a normal installation, the
sectors are restored without affecting SIP Main. However, if power is removed during Boot
installation, then SIP Main is erased and will have to be reinstalled on the phone.
Automating Firmware Upgrades
You can configure phones to poll the server for new versions of firmware. When the phone
detects a firmware upgrade, it downloads the new version and stores it in memory. When it is
next idle, the phone reboots with the new firmware.
To automate firmware upgrades, Administrators can set a Firmware Upgrade option and a polling
interval on the Firmware Update page of the Web Configuration Tool. For programming options,
refer to the online help supplied with the Web Configuration Tool.
To upgrade firmware on multiple phones, refer to the Mass Deployment topic in the Administrator
Tools section of the Web Configuration Tool Online Help.
SRTP Call Encryption Indicator
For information about the Call Encryption setting, see Call Encryption Indicator on page 7. Also
refer to the Configuring Protocols topic in the Administrator’s Web Configuration Tool Online
Help.
