  • Right-click the DHCP server and then select Set pre-defined options.
  • Click Add.
  • Set Name to IP Phone Boot Server.
  • Set Data Type to String.
  • Set Code to 156 and add a description, if desired.
  • Navigate to the scope options and add option 156.
  • Set the value of option 156 to: ftpservers=xxx.xxx.xxx.xxx, country=1, language=1, layer2tagging=1, vlanid=xx
