The Woodland Hills, Calif., company is currently offering three-months of its paid service at no charge. Prices range from free to $14.95 a month, which includes phone-to-computer calling in the United States, Canada and Puerto Rico. International calling starts at two cents a minute.
The service works on any broadband connection.
VoIP calling is growing in popularity as a cheaper alternative to traditional telephone service. Cable operators have started offering the service to compete against telephone companies that are moving toward selling TV subscriptions through broadband.
