You can do direct SIP to SIP calls without using the PSTN - but like

So I guess if you have ADSL then you'd need a router which could do
bridging or something along those lines so the Asterisk box is
potentially getting the internet IP address?

Or an ISP that will provide you with a routed netblock over your ADSL
line, allowing you to have a router on the ADSL line and behind it a
DMZ for your asterisk box (and perhaps other stuff too) and a firewall
doing NAT and protecting the main office network.

Ahh right, like 5 useable internet IP addresses?
