you are giving these as text strings, but the phone actually requires IP
addresses or numbers.
you can patch like this,

these ones have a whole bunch of clashes with other vendor options (see
http://www.iana.org/assignments/bootp-dhcp-parameters/) and they aren't
assigned or tentatively assigned, so I don't think they can be hard-
coded into our dhcpd by default.
