  documents the current usage of the option in agreement with
  [RFC3942], which declares that any pre-existing usages of option
  numbers in the range 128 - 223 should be documented and the working
  group will try to officially assign those numbers to those options.

RFC Editor Note

  Please change the title of the document as follows:

  VoIP Configuration Server Address Option
  VoIP Configuration Server Address Option for DHCPv4

  Please add this to the end of the abstract:

  The option is defined for DHCPv4 and works only with
  IPv4 addresses.

  Please change this in Section 5:

  If this is a concern, then DHCP Authentication may be used.
  If this is a concern, then DHCP Authentication may be used, but
  even secure delivery of an address over DHCP does not protect
  the subsequent insecure download over TFTP.
