What is it?

One of the problems with PC-based Internet telephony is the need for a headset, which many people find clumsy and cumbersome. Of course, you can get away with using your desktop speakers and a separate microphone if you want to deal with poor sound quality and plenty of echo.
ChinaRoby has come up with an alternative using the ubiquitous USB port to create USB-based multimedia VoIP handset phone. Simply connecting it to an available USB port of your PC, you will be able to start using it in no time. Its full duplex audio and echo cancellation have made it the ideal VoIP device for you.
