DHCP Server on CentOS 6.4

I am setting up an Asterisk server. It is a Dell T110II with 2 NICs. I am running CentOS 6.4. My goal is to have two seperate networks. One for the Internet-accessible LAN (eth0), and one for the private non-internet-accessible LAN for the VOIP phones.

eth0 - needs Internet access. Plugged into the existing data switch with other PCs, printers, etc.
     IP               10.79.10.1
     Subnet        255.255.0.0
     Gateway     10.79.0.1
     DNS            10.10.0.99

eth1 - no Internet access needed. Plugged into a stand-alone, seperate switch
     IP                192.168.0.1
     Subnet         255.255.255.0
     Gateway      none
     DNS             none

I have installed dhcp on the server in order for the SIP phones to pick up and address during boot. Here is the dhcpd.conf file...

     #
     # DHCP Server Configuration file.
     #   see /usr/share/doc/dhcp*/dhcpd.conf.sample
     #   see 'man 5 dhcpd.conf'
     #
     default-lease-time 259200;
     max-lease-time 518400;
     ddns-update-style none;
     authoritative;
     subnet 192.168.0.0 netmask 255.255.255.0 {
     range dynamic-bootp 192.168.1.10 192.168.1.99;
     option broadcast-address 192.168.0.255;

Here is my /etc/sysconfig/dhcpd file

     # Command line options here
     DHCPDARGS=eth1

My questions is...what am I missing? The phones are not picking up an IP address from DHCP.

Thanks
