Phone Provisioning

l PnP: PnP feature allows IP 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 IP phones. When the IP
phone requests an IP address using the DHCP protocol, the resulting response may contain option 66 (for IPv4)/op-
tion 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 phone user interface or web user interface.
