DCHP point to tfpt server???

has anyone set up os x server DHCP to supply tftp information to an IP phone? I am new to IP telephony (although I have been using os x server since 10.3). If I understand correctly, the DHCP server will supply the tfpt server information and the IP phone will download the configuration files from there... I would like to continue using my os x server for DHCP... is this possible?
