History
The first steps developing Call you Free Technology dated from 1995/1997. They were conducted by Claudio Rosemffet from the University of Belgrano (Argentina), Pablo Cuello from de University of Buenos Aires and Fernando Speranza from de University of El Salvador, with the main purpose to connect the companies of the Mercosur (Southern Common Market), a Regional Trade Agreement (RTA) among Brazil, Argentina, Uruguay and Paraguay, founded in 1991.
During that first stage, the results were not satisfactory at all due to the low bandwidth of the dial up internet connections, that could not provide more than 33 kbit/s. Since 2001, when ADSL technology became available in those countries, the second stage started achieving a good audio quality and getting better connectivity with no more audio breaks.
In June 2009 a new technology was introduced making the communication process through the Web even better and simpler.

Famous quotes containing the word history:
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
“We don’t know when our name came into being or how some distant ancestor acquired it. We don’t understand our name at all, we don’t know its history and yet we bear it with exalted fidelity, we merge with it, we like it, we are ridiculously proud of it as if we had thought it up ourselves in a moment of brilliant inspiration.”
—Milan Kundera (b. 1929)
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
