Vonage

Vonage Holdings has helped to ring in a new era of communications. The company's computer telephony service enables customers to turn their high-speed Internet connections into long-distance phone lines for domestic or international calls. A leading provider of broadband Voice-over-Internet Protocol (VoIP) telephony services, the company has about 2.4 million subscriber lines in operation. Vonage primarily serves consumers in the US, but it also has a number of small business clients and it does business in Canada and the UK. The company markets its services directly and through such retail partners as Wal-Mart and Frys Electronics.
