EarthLink will announce Tuesday that it is expanding its line-powered Internet-based phone service to eight more cities throughout the United States.

Beginning this month, customers in Atlanta, Chicago, Los Angeles, Miami, New York City, Philadelphia, San Diego and Washington, D.C., will be able sign up for Home Phone Service, EarthLink's voice over Internet Protocol phone service.

The service is competing in an already crowded market where cable operators, standalone VoIP providers such as Vonage and Skype, and Internet companies such as AOL, Yahoo and Google are all trying to get a piece of the telephony market.
