VoIP provider Vonage will rely on digital tablet devices such as Apple's iPad to help it get back into profitability, according to company CEO Marc Lefar. The company has an app planned for the tablet and has the ability to video and messaging to its service. At the same time, Lefar mentioned that a software or phone company may want to partner with Vonage to access its technology, but did not say whether a partnership or acquisition are indeed being discussed.
