What’s a USB Phone?
The USB phone is a corded or cordless telephone that can be connected to a USB port on a PC. If you press the "List/Call" button, the display on the USB phone shows your Messenger contacts and whether they are online. If they are, you can simply press the talk button to speak to them for free using Yahoo! Messenger with Voice.
Where's the Contact Customer Care button? With so many improvements to Messenger since the version you're using (lots more features and reliability), we figured you're ready to move up. So get your upgrade and with the new version, rest assured if you have questions, you’ll find that friendly button on its help pages.
