Free, unless you want to make calls to phone numbers from Skype.
As long as you are making skype to skype calls and not skype to "real" phone numbers then it is completely free no matter where in the world the other person is.
That number is from a network called Skype. Skype is a site where you can chat with your family and friends with webcam. People without Skype get confused about these numbers because only Skype users know its a Skype number. I know because I have Skype myself.
You can have a Skype account for free, and talk with other Skype users for free. If you want to use Skype to call regular phone lines, there is a cost for that - but no monthly fee.
Use Skype, Skype allows you to call US 1-800 numbers

People can purchase subscriptions and credit to make phone calls to actual phone numbers and to have voice mail on their Skype.
No Skype calls can go on for as long as needed. There is not cutoff or anything like that unless you are calling a mobile number. Then it cuts off when you run out of credits.
Yes, numbers are unlimited.
A lot of things can be rich but for the consumers it is free. Markets buy skype and sell the cameras but skype is a free communication device. The skype inventors get the money the market pays them. Hope I helped. :)
"If you have a Skype account, you can gain credit just by purchasing. You can use your credit card or PayPal account to purchase credits on Skype and use those credit to make phone calls to telephone numbers all over the world."
