For starters, you should probably define this only to a subset of the
phones. Look into defining classes, "nets", in the terminology of
dnsmasq. Those are basically just arbitrary groups of clients (e.g.: all
the SNOM phones). The 'net'[work] name parameter is an optional
parameter in many places. For now I'll just ignore it.

What version of dnsmasq do you use?

The man page for dnsmasq here claims:

       -O, --dhcp-option=[<network-id>,[<network-id>,]][vendor:[<vendor-
       class>],][<opt>|option:<opt-name>],[<value>[,<value>]]

  ...

         The  option  numbers  are  specified  in
         RFC2132 and subsequent RFCs. The set of option-names known by
         dnsmasq can be discovered by running "dnsmasq --help dhcp".

IIRC at least in some phones the protocol 'ftp' is not taken from DHCP.
Rather, it is defined in the phone. I also wonder how wise is it to
broadcast an authentication token in a protocol such as DHCP.

And last but not least, as part of recent race for feature bloat, latest
versions of dnsmasq also double for a tftpd.
