Earthlink and Covad are working together on Line Poweed VoIP. Customers can use their existing phones and plug them into phone jacks as they would with any regular telephone service. The technology, called “line-powered voice,” puts all the intelligence and equipment for offering VoIP service in Covad’s central office, where all the gear to provide the DSL service is housed.

This approach differs from that of most other VoIP services, such as Vonage’s. Those services require a special adapter to be hooked to the phone and the broadband connection. “The line-powered service works just like a plain old telephone system,” said Jim Bagnato, director of voice services for EarthLink. “You simply plug your existing phone into the wall and it works. But the calls go over an IP network, so you’re also able to get all the IP features.”
