I just ordered a couple of these voip blasters (two for $26 with shipping
and tax from Creative Labs).  It uses the h232 protocol so the ip_masq_h323 do the 
masquerading stuff.  For
outgoing calls all you need is the h323 masq stuff - incoming calls is where you need 
the port forwarding.
You can open the appropriate ports
and forward them to a single machine.  Port forwarding only works to one
destination so if you run several of these behind the same firewall you will have to 
use different ports for
each one.

The nice thing about these usb devices is that they have a digital signal
processor for clarity and echo elimination  and a ringer to ring the phone.
