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:
l
Zero Touch: Zero Touch feature guides you to configure network settings and the provisioning server address
via the phone user interface after startup.
l
PnP: PnP feature allows the phones to discover the provisioning server address by broadcasting the PnP
SUBSCRIBE message during startup.
l
DHCP: DHCP option can be used to provide the address or URL of the provisioning server to phones. When the
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.
l
Static: You can manually configure the server address via the phone user interface or web user interface.
