	I really think you should read the documentation for Asterisk.  The
only requirement to connect a phone from outside your network is that
the IP address of the * server is accessible from the Internet.  You can
either have a public IP for your server or use a DMZ if you are behind a
NAT router.  You only have to configure the phones with the correct IP
address and they operate exactly the same as the internal phones.

	The only thing you should consider is using voice compression to save
bandwidth.  Maybe buy a few G.729 licenses or at least use G726-32.
