Provisioning Server Discovery Methods

After the phone has established network settings, it must discover a provisioning server to obtain software updates and configuration settings using one of the following methods:
  • Static You can manually configure the server address from the phone menu or Web Configuration Utility, or you can provision a server address using device.prov.serverName and corresponding device parameters.
  • DHCP A DHCP option provides the address or URL between the provisioning server and phone.
  • DHCP INFORM The phone makes an explicit request for a DHCP option. Note the phone request can be answered by a server that is not the primary DHCP server. For more information, see RFC 3361and RFC 3925.
  • Quick Setup This feature takes you directly to a screen to enter the provisioning server address and information. This is simpler than navigating the phone menu to configure provisioning parameters. For more information, see Using Quick Setup with Polycom Phones: Technical Bulletin 45460 at Polycom Engineering Advisories and Technical Notifications.
  • ZTP If the phone does not discover a provisioning server address automatically using DHCP and you are not using a static address, the phone contacts the Polycom Zero-Touch Provisioning (ZTP) server and requests initial configuration files, including the address of the service provider or enterprise provisioning server.
