Alright so I've tried searching and tried everything I could.

I have a IBM xServer 335 with Dual NICs running the newest version of TrixBox. So the phone was having a application load error and doesn't allow you to get into any of the menus. I finally got the phone to pull a IP via setting up a DHCP server on the IBM box. However then it would go and try to connect to the TFTP and just timeout. Even though DHCP was set with the option to give the phone the TFTP info.

Does anyone have any ideas?

It sounds like you have that set up correctly.. You should have tftp directory in your root menu. Inside - you should have the appropriate files for your phone.

SIPDEFAULT.CNF, SIP{macaddress}.cnf, your load files, dialplan, syncinfo, etc.

Once those files are there and configured correctly, you should have no problem loading your 7940.

The DHCP server (in the dashboard gui) will assign the necessary lease to the phones once set up correctly and the TFTP server will shoot the load info over and youre done.

Im presuming your phone already has a sipload. There are many variables with cisco, although once done correctly, it is easy from then on.

Hope this helps.

Is there a way to setup the DHCP to be on only the 2nd Nic? I want to setup the 1st one to connect to the network, then the phone to be on the 2nd NIC receiving a IP from the server, at least for the initial setup.

trixbox / routing / dhcp

Have a look at this thread.
http://www.trixbox.org/forums/trixbox-forums/help/tftp-server-dhc...
You need to make sure that you have a route via your second nic (probably eth1) to your local subnet. You need to configure your dhcp server to offer a range of ip addresses in your local subnet address space. If your routing is correct and your phones are on the local network you should then be OK.

I wrote a Cisco 79xx how to http://www.cat24.net/Cisco_Sip_Phones.html

The dhcpd.conf I used is

cat /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;

option voip-tftp-servers code 150 = ip-address;
option voip-tftp-servers 192.168.0.130;

subnet 192.168.0.0 netmask 255.255.255.0 {
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
option nis-domain "";
option domain-name "";
option domain-name-servers 192.168.0.1, 217.x.x.x;
option ntp-servers 192.168.0.130;
option tftp-server-name "192.168.0.130";
range dynamic-bootp 192.168.0.150 192.168.0.175;
default-lease-time 3600;
max-lease-time 7200;
}

Hey I've gotten the box to server a DHCP and the phone connects to the TFTP However the phone says TFTP file not found.

In TFTP I Have

sftp://192.168.1.100//tftpboot/797x_template.cnf.xml

sftp://192.168.1.100//tftpboot/snom.cnf
sftp://192.168.1.100//tftpboot/syncinfo.xml

The TFTP Log Lists This

So I noticed there's no SIPDefault.cnf and MGCDefault.cnf so I don't know where it's serving it from.

Alright so I got it up and working and everything. Now, the question is, is it possible to set it up to do outbound or inbound calls, either or.

I know with a setup where you have access to the router you can and firewall. However I'm doing this from my Dorm Room at College to learn more about it.
