First of all voip was cutting edge in 2000/2001 today it is fairly common. For example you may have noticed your cable company offers telephone service, that is voip based. The reason this may burst your bubble is a company providing the service you describe would need at aleast $500k-$1m of angel funding just to get started. this is assuming your equity partners know how to design and build out the system because consultants in this field are NOT cheap. to give you an idea some of the weekend contract work i do outside my normal job is $8k a weekend.
First of all there is the facilities aspect. basically at some point that voip based call is going to have to be dumped into the PSTN cloud. I have worked with several companies that will give you less that $.01/min for calls with month to month contracts and will accept raw VoIP calls and place them onto the PTSN though their network. but if you are doing international calls for example by far the cheapest way to go would be to have facilities in the US and in Europe, contract Qwest or verizon to lease bandwidth across the atlantic and transfer calls from the US across your pipe to your facility in europe and place calls onto the cloud there. the savings come from not getting nailed by tariffs and such when calls leave the US because they are data at this point. the reason it would cost so much is you have to build at a somewhat decent backbone, have the servers that can convert VoIP to TDM and your local and LD costs for termination at the sites.
Now there is a cheaper way and that is to not own your network, either by co locating a few servers and partnering with a well funded up an coming VoIP LD company, so you would take the initial request for the call then dump it onto their network to set up and transport, that would make you more of an advertising company though since you are really getting people to pay you for a service you have basically just outsourced (BTW don't expect good international rates in this scenario). However although the technology to do is rather simple and quite mature now adays, it is not cheap. no matter what IP pbx company you go with to try and do this expect to pay boatloads ($50-$100k) for it if you are building out for any level of volume (100+ simutainous calls)
hope that give you a little bit of an idea. it is by no means all encompasing but remember VoIP is just set up messages with a data stream so it is all about network, bandwidth and latency (don't even think about bouncing VoIP calls off satilites to get around internation bandwidth prices unless you want conversations to end up like nextel direct connect calls, beep... person A talks, long pause, person b respons, long pause etc...)
