TFTP option 150 for VoIP Phone in dhcpd.conf on Linux

  Since I'm not able to reply to the archived posts from earlier this
year when people were asking how to do this, here is a quick config for
anyone doing a websearch now or in the future. This is an example of how
to use a linux dhcpd DHCP server to hand out ip address leases and
specify the TFTP option 150 for VoIP phones in the dhcpd.conf config

# /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;

# Define Custom Options
option option-150 code 150 = ip-address;

# Global Config

option ip-forwarding off;
option nis-domain               "domain.local";
option domain-name              "domain.local";
default-lease-time 21600;
max-lease-time 43200;

subnet netmask {

	option routers; 	   	#
Default Gateway
	option subnet-mask;
	option broadcast-address;
	option domain-name-servers;
	option nntp-server;
	option time-offset		-18000;			#
Eastern Standard Time
	option option-150;
# TFTP Custom Option
# TFTP Boot

	range dynamic-bootp;
