Circuit City picks up AT&T Net phone plan

The retailer will sell CallVantage in many of its outlets and through its Web site.

Beginning Friday, consumer electronics retailer Circuit City will sell AT&T CallVantage Net phone services in many of its outlets and through its Web site, the two companies said on Wednesday. CallVantage is also available at Best Buy stores.

CallVantage is an example of a new type of telephone service in which the calls travel over the Internet, rather than over the heavily taxed and regulated traditional phone network. The AT&T service is being sold on as well as through co-marketing deals with cable companies such as Comcast and Cox Communications.
