I just moved my ooma hub behind my router and it still seems to work fine behind the NAT firewall in the router. On the following page it mentions about ports, etc that are used for outbound traffic. How does ooma get inbound calls? Can I improve performance by putting my ooma in DMZ or port forwarding those ports to it?

As long as your Ooma Telo is functioning properly, you shouldn't have to Port Forward the listed ports or put the Ooma Telo's Internet port MAC address in the router's DMZ.

I have had my Ooma Telo behind the Router, without Port Forwarding, or using the DMZ, for a long time and it works great.

Ooma uses an encrypted vpn to their server(s) in California.
Most home routers do not have an outbound firewall.
Any program on a PC can specify what ports it wants to be open for the return connection.
They are opened when the connection is set up and closed when the connection is torn down.
The same is true for the operating system running in the Ooma box.

Unless you have a commercial router (hint: it was extremely expensive) no port configuration is required.
DMZ won't hurt but it also won't help.
