(Via S+B)The most attractive new form of Internet telephony is also the most threatening to corporate security — for now.Unlike the growing number of VOIP networks offered by phone and cable companies, Skype is a peer-to-peer system. Skype is a "softphone" - a software-based telephone that uses a computer, cellphone, PDA, or any other equipment connected to the Web to deliver voice with simultaneous file transfer and instant messages over the Internet. This means that it creates ad hoc computer-to-computer links over the Internet whenever Skype users want to reach one another. With this approach, no central networks mediate or manage the connection. As Skype eliminates the middleman, calls between its users are free. The company generates revenue by selling services that allow subscribers to make calls to people who haven’t downloaded the software. Skype’s sound quality is better than typical telephone reception, primarily because it is not limited to the standard telephone transmission spectrum of 300 Hz to 3 kHz, a relatively narrow bandwidth. Since its debut, Skype has signed up 35 million users and, at any one time, well over 3 million people are logged into its network. With all of this, Skype would seem to be on a smooth trajectory, but that’s not quite the case. Most corporate IT and telecom managers are trying to avoid Skype at all costs.
