Can DHCP service support option 120?

Hi,all
Can DHCP server support option 120 via configure dhcpd.conf?

(DHCP version is dhcp-server-3.0.1rc13-28.20)
My dhcpd.conf is:
option SIP-Servers code 120 = ip-address;
option SIP-Servers access.sz.ngims.cmcc.com;
option domain-name “sz.ngims.cmcc.com”;
option domain-name-servers 2.1.37.100, 2.1.37.200;
option routers 2.1.1.254;
ddns-update-style none;
subnet 2.1.37.0 netmask 255.255.255.0 {
range 2.1.37.0 2.1.37.254;
}

Yes, ISC dhcpd can can support arbitrary options…

Thank you,ken_yap.
I am a fresh man in DHCP field.
The question is my DHCP server receive the DHCPINFORM, and not send any messages to DHCP client,why?

What is an INFORM supposed to do? I am only familiar with DISCOVER, REQUEST and RELEASE as well as the replies ACK and OFFER. Perhaps you need to refer to the RFCs to find out what the protocol is for INFORM.
