You can do direct SIP to SIP calls without using the PSTN - but like Skype, the other end needs something compatible. (And NAT is going to stop it working anyway)

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?

Would setting up the Asterisk machine as a DMZ machine (so everything by default goes to it) work?
I've seen it done using 'standard' software but not been able to achieve it at home - avoiding NAT problems by tunneling - something that should be taught in primary schools really! That open router would be nice - I bet you could stick ser on that and way you go..
