Thank you for the config. I modified it the best I could (noob that I am.)
however when the CM asks for an IP, I get the following:
Apr 2 15:45:37 localhost dhcpd: Listening on PF/eth0/00:0d:61:42:dd:ba/ABCD
Apr 2 15:45:37 localhost dhcpd: Sending on PF/eth0/00:0d:61:42:dd:ba/ABCD
Apr 2 15:45:37 localhost dhcpd: Sending on Socket/fallback/fallback-net
Apr 2 15:45:37 localhost dhcpd: dhcpd startup succeeded
Apr 2 15:46:14 localhost dhcpd: DHCPDISCOVER from 00:15:96:27:a1:8c via
10.105.100.1: network ABCD: no free leases
Router ip is 10.105.101.1
Dhcp server is 10.105.101.2
Tftp server is 10.105.101.2
Syslog server is 10.105.101.2
CM range is 10.105.100.5 10.105.100.100
Mta range is 10.105.100.101 10.105.100.200
Cpe range is 10.105.200.5 10.105.200.100
Any suggestions would be greatly appreciated.
Here's the edited dhcpd.conf :

Thanks, I think I can work with this. Two newbie questions
1. in 01:04:0a:00:00:02 01 = option 1 and 04:0a:00:00:02 = 10.0.0.2
correct ?
2. Is there a option 122 calculator or calculator to convert ip 10.0.0.2 to
04:0a:00:00:02
Thanks for any help
Horacio

Under your global options
option voip122 code 122 = string;
under your subnet options
option voip122 01:04:0a:00:00:02;
you may need an option 122 calculator to create the 122 value.
this example one is equal to option 1 primary server = 10.0.0.2
Hope this helps.
