P2P chega à Telefonia ?
...
Digital troublemaker Jeff Pulver is at it again. This time, he's unleashed a way to use the Internet to let anyone use your phone to make a call.
And, conversely, you can place calls all over the world--often for free--by "borrowing" someone else's phone.
Bellster, as Pulver's new creation is called, smashes yet another telephone industry tradition. Until Bellster's release about a week ago, it was very difficult--if not impossible--to share a phone line with someone else without the phone company's consent. But now it's happening, thanks to voice over Internet Protocol, or VoIP, a burgeoning technology that lets Internet connections double as local phone lines. VoIP is the underlying plumbing in Bellster's system, which ultimately lets people call any type of phone.
...
Early concerns are the expense, possible law abuses and the limited number of potential users who have the required server savvy. Typically, commentators think highly of the idea but pan the cost and the required technical sophistication. "It is, unfortunately, not for mere mortals," Alec Saunders writes on his Web log. On Slashdot, a reader offers dialogue instead of traditional commentary: "RING. 'Hello?' 'Hi, is your server running?' 'Well, you'd better catch it!'"
...
Like most new technology, Bellster necessitates much assembly of expensive equipment, and the software has so far only managed to attract a few hundred users since its recent release.
The basic ingredients are a local landline or cell phone line, a personal computer loaded with phone software known as a soft phone, and a server storing software from an open-source PBX (private branch exchange) called Asterisk. A PBX is essential to direct phone traffic. Also required is a converter for connecting your phone line to the Internet.
Next, minutes of calling time are needed. Where do all these minutes come from? People donate them, largely from the package of unlimited calling they have. Initially, Bellster users can only make calls if they donate calls.
Once the pieces are in place, Bellster creates what Pulver calls a "telephone cooperative." The call begins on someone's computer using the soft phone. It's broken into bits of data that travel over the Internet to a Bellster member's computer in the vicinity of the call's destination. The call then jumps back onto the traditional phone network using the Bellster member's local or cell phone line, which completes the call.
