Abstract
In 1870, Alexander Graham Bell created the wired telephone but he never thought that his invention would take such a direction. A few years ago nobody could have imagined that it would be possible to use telecommunication systems without paying anything. With the Internet technologies, the long reign of the phone knowing little innovation during all those years underwent a veritable revolution with Internet and the VoIP.
The personal computer and the Internet 2.0 invention allowed multiple innovations in term of new technologies and for the communication industries. Voice over Internet protocol (VoIP) was the last innovation that offered different possibilities like video communication, voice and text/data capabilities over internet. This new process allows strong business opportunities and served the public interest.
New technologies like those developed by Niklas Zennstrom and Janus Friis who developed Kazaa and Skype, are based on the possibilities that offers the Internet. Skype developed by Skype technologies S. A capitalized on the VoIP trend and gave the possibility to discuss over Internet for free with using a peer-to-peer process (P2P).
