The company I work for has had their firewall team setup an interface on our sites Fortigate Firewall with two subnets (one for voice and one for data).  Our data network is 192.168.1.144 subnet 255.255.255.0, and our voice network is 172.20.120.128 subnet 255.255.255.240 with VLAN ID 10.  The gateways programmed onto this device is 192.168.1.145 and 172.20.120.129.

On the internal side of the Fortigate I have a stack of Dell 3348s.  I currently have the switch programmed to have an ip address of 192.168.1.146 using the default VLAN ID 1.  The switch is passing data happily.  I now need to program the switch to handle the voice traffic as well.  

I need to use VLAN ID 10 for the voice traffic.  What do I need to do?  I have listed a few steps but I'm not sure they're correct.  Anyone with this setup able to shed some light?

- Create VLAN 10 on 3348
- Assign VOIP server port on the switch to be in ACCESS mode for VLAN 10
- Place the port conencting the switch and Fortigate into TRUNK mode.

If I place the switch into trunking mode will I need to tell it to allow VLAN 1?  Does this setup seem right?

Just as a follow up, I answered my own question.  The process I listed is a pretty good approximation of the steps needed.  Thanks.
