If you change this parameter, the phone will reboot to make the change take effect.

Supported Provisioning Server Discovery Methods

After the phone has established network settings, it must discover a provisioning server to obtain software updates
and configuration settings.
The IP phone supports the following methods to discover the provisioning server address:
Zero Touch: Zero Touch feature guides you to configure network settings and the provisioning server address
l
via the phone user interface after startup.
PnP: PnP feature allows the phones to discover the provisioning server address by broadcasting the PnP
l
SUBSCRIBE message during startup.
DHCP: DHCP option can be used to provide the address or URL of the provisioning server to phones. When the
l
IP phone requests an IP address using the DHCP protocol, the resulting response may contain option 66 (for
IPv4)/option 59 (for IPv6) or the custom option (if configured) that contains the provisioning server address.
Static: You can manually configure the server address via the phone user interface or web user interface.
