"Offering broadband phone service to our customers is a natural fit for Buy.com. Our customers are extremely tech savvy-they are interested in VoIP technology, and appreciate its unique features and great savings," said Keith Allen, Buy.com senior vice president of sales."

"Buy.com is a great Internet destination where online shoppers can quickly and easily purchase a wide variety of consumer products and services," said Cathy Martine, AT&T senior vice president of Internet Telephony. "This agreement is another step in making our service more widely and conveniently available to as many consumers as possible. We expect VoIP will be on many shopping lists especially with the holiday season approaching."

AT&T CallVantage Service is now available to consumers in more than 170 U.S. markets coast-to-coast and is currently being trialed overseas for use by remote workers of U.S. multinational corporations. All that's required to use AT&T CallVantage Service is a telephone adapter provided by AT&T and a broadband connection, which lets consumers talk over high-speed Internet connections instead of traditional circuit-switched phone networks.

AT&T CallVantage Service is different than traditional phone services because, through the use of IP-based networks, it can offer customers typical features such as call waiting, three-way calling, and call forwarding, as well as far more advanced features. Indeed, consumers will get unprecedented convenience, cost savings, and control with innovative features including:
* "Call Logs," to track incoming and outgoing calls;
* "Do Not Disturb," to receive calls only when wanted;
* "Locate Me," which rings up to five phones, all at once, or sequentially;
* "Voicemail with eFeatures," to listen to messages from any phone or PC and forward them to anyone on the Web;
* "Simple Reach(SM) Number," which enables AT&T CallVantage Service customers to add up to nine additional telephone numbers anywhere in the country where AT&T offers residential VoIP service for $4.99 each; and
* "Personal Conferencing," to set up meetings with up to nine additional callers.
