Firmware Upgrade<br />

The Firmware Upgrade page lets you enter a source URL <strong>for</strong> a software upgrade to the<br />

phone. Clicking the “Upgrade” button preserves the current phone configuration, while<br />

upgrading the software (this is the preferred option). In some cases, the firmware release<br />

notes will instruct you to choose the second option “Upgrade & Set factory Defaults”. This<br />

second option is required when differences between the software versions are so great, that<br />

the existing configuration cannot be preserved. When using the “Upgrade & Set factory<br />

Defaults” option, refer to the firmware release notes <strong>for</strong> instructions on how to restore you<br />

configuration from saved files.<br />
