"Ezmax of South Korea will put on sale this May an MP3 player that allows users to make and receive telephone calls using VoIP (voice over Internet Protocol), the company said at the CeBIT trade show here. The EZMP4200P contains software so that when the device is linked to an Internet-connected PC via a USB 2.0 port, people can make local and international calls using a microphone that is included in the device's earphone cord, says Ezmax's director, Lee Sung Soo. When the device is connected to a desktop or notebook PC, it appears on screen as a removable disk icon. When the icon is double clicked, dialing software appears, enabling the user to make calls, he says."You've gotta love those Korean companies who come up with the craziest things, no matter how impractical. I can't see this being all that useful at the moment, but they'll learn from this and perhaps down the road we'll see VOIP merge into other devices.
