CYF is the abbreviation of CALL YOU FREE. Call You Free is a free web communication service originally developed to encourage communication in the internet community, the internauts.
However, several tentatives failed at the beginning and internauts took some time to approve the initiative because of hardware and bandwidth limitations by the time it was developed. Other developers released similar products but the distinctive features of Call You Free was that it used Click2Call Technology, that lets the caller place his webcall using a webphone within a browser. Remember that all the earliest transmissions of voice over internet protocol required separate software to establish the communication. We are talking about using only the internet browser. That was really a new concept.
Many complaints fall over CALL YOU FREE, specially from the open source community, because originally it was developed to run for Microsoft’s Internet Explorer (version 5 or higher), but today other developers joined the project to develop it for other internet browsers.
