Broadband telephone company Vonage is expected to announce plans Tuesday for a Wi-Fi phone that could make calls through a customer's wireless home network or at wireless hotspots, USA Today reported Tuesday. Vonage says it would work like a cell phone, but would not cost the subscriber any additional fees to use the service.

Vonage expects to be able to offer the phone to its 400,000 subscribers at a cost of about $100 per device. According to CEO Jeffrey Citron, it's a feature that Vonage has been planning to add for quite a while. "Our customers are asking for it," he said. The phone should be available by June of this year.
