Handset USB Phone:
Handsets feel so much like your standard home telephone that you'll forget you're calling over the Net, until you see the huge savings. These handsets provide a private, quiet alternative to PC microphone and speakers.
Wireless 2.4GHz VoIP Phone (dual mode):
A headset allows you to call while having both hands available to type, use other programs, take notes or move around while talking. This hands free aspect is a major benefit to using a headset.
A broadband phone is a device that allows you to make calls with a regular phone over high-speed Internet connections, such as Cable or DSL. The advantages are tremendous: no computer is necessary, superior sound and regular telephone experience. With broadband telephone services you can make and receive calls worldwide over your broadband Internet connection.
