This was on Nightline tonight along with a youtube of a tech asleep waiting for comcast to come on the line.
I'm looking at skype myself.
I'm open to suggestions.
It does seem you can use different protocols with it and one is stereo with good quality.
You can use voip person to person without using any company.
I've used comfortel for rebuilt Plantronics headsets and companders for land lines and been exceedingly pleased with their service.
They have voip sets too.http://www.comfortel.com/index.html
I have my own VOIP over IPV6 network that spans from here to Palestine and it is by far the most efficient I have ever built.
I plan to put it online for business soon.
As far as just making free long distance calls, one can also try talkster.com
as far as VOIP is concerned, anyone can make a better network than Vonage or Skype if one is willing to take the time to install what is needed in the home.
Linksys makes routers that are VOIP ready called ATA's.
They were originally made by Sipura but Linksys bought them about 2 years ago. An ATA is a module you hook up to your computer, a brodbad line and a regular phone to make long distance phone calls with.
It's what Vonage uses. In fact, Vonage also has a deal with Linksys implementing their software in the new linksys routers.
Anyhoo, the main reason why I do VOIP over IPV6 is long distance phone calls in HD. Video and audio..
If you want to experiment with your own VOIP get an ATA, (if you can find a Sipura, that is one great way to go.) and here are some links:
