I'm a bit new to VoIP and would like to setup a peer-to-peer system. I've got a couple of mates around the world (and two here in Australia) and would like to setup the PC to be able to receive and make calls to a VoIP phone via broadband. We all have cable/adsl which is always on through the use of a netgear router. Ideally i'd like to be able to plug my ip phone into my router and then my PC into the phone, so when someone calls me some software on my PC picks that up and forwards it to the phone. Maybe use something like email addresses or internet IP Addresses or even a domain name as the "phone number". I'd prefer not to have to setup a gateway server and have my friends call through that as i don't want to have to pay for bandwidth they use when they call and talk to each other!!!
It's basically just the next level up from using Netmeeting. I'd like the phone to ring and to use it like a normal phone. It doesn't need a connection to the PSTN network, as i only want it to be used for calling other friends with an IP Phone, eventually getting them all up and running!
Any suggestions or places to start looking?
