We are installing NEC phones and would like to use LINUX as our DHCP server. It is working as far as giving the phones and IP etc. but I can't get it to send option 120 for the sip server.

In the dhcpd.conf file I have:

option option-120 code 120 - string; (at the top)

Then, in the lease area I have:

option option-120 AC:10:01:02;

The service starts fine but the phone says it can't find the server.

Any help would be appreciated! :-)

I found out what the issue was. I needed to add 01 before the Hex.

Like this 01:AC:10:01:02

Now, does anyone know how to add a second SIP server?

Got it!

Just continue adding. Like this:

01:AC:10:01:02:AC:10:01:03;

Thanks.
