Using a UC320 as a SIP gateway

This is a design question.

From what I have read, the UC320 does not have a built-in firewall.

If this is the case, it appears that I need a separate appliance to be my Internet firewall.

Is it standard practice to pass SIP through a separate firewall appliance, where this SIP trunk will terminate on my UC320?

My UC320 will be behind the firewall appliance:   Internet -> Internet Firewall -> UC320--Lan--pcs and phones.

The feature-guide talks about a basic firewall in the UC320 with basic port forwarding:

But It's a voip-device, probably without real security in mind. So I would never place it directly onto the internet without a dedicated firewall. My UC320 is sitting in the DMZ, but not with a SIP-trunk to the internet because I'm using the Mediatrix gateway for BRI.
