AT&T and NEC have jointly implemented a Voice over Internet Protocol (VoIP) solution at Omron Corp in Japan. By establishing this VoIP network, Omron expects to reduce costs by approximately US$500,000 annually. The migration to VoIP began in November 2004, and after voice-switching testing and other preparations, over 10,000 telephones nationwide were switched in just two days. In this project, AT&T was responsible for project management, network design, equipment/line selection, test and operational support. NEC installed VoIP equipment, including Univerge SV7000 servers and VoIP gateways at all locations. AT&T works with Omron on a global level, and has implemented an AT&T Internet Protocol Virtual Private Network (IP VPN) solution at 53 business locations in 19 European countries, 15 business locations in 9 countries in the Asia Pacific region. The VPN solution also has been extended to the United States.
