TOKYO -- AT&T and NEC Corporation (TSE: 6701; NASDAQ: NIPNY) announced today that the two companies have jointly implemented a Voice over Internet Protocol (VoIP) solution at OMRON Corporation (OMRON) in Japan. By establishing this VoIP network, OMRON expects to reduce costs by approximately half a million US$ 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 SIP server "UNIVERGE SV7000" and VoIP gateways at all locations.

AT&T works with OMRON on a global level, and has implemented an AT&T IP-VPN solution at 53 business locations in 19 European countries, 15 business locations in 9 countries in the Asia Pacific region, and has also been extended to the U.S. The network provides the foundation for the company's global, seamless business operations.

"We are honored to provide VoIP services to a global company like OMRON," said Norihiko Minato, President of AT&T Japan. "We continue to contribute to helping our customers achieve greater efficiency in business operations and grow by using the skills and technology we own on a global scale."

"We are very proud to take part in providing the VoIP network solution to OMRON," said Kazuo Tsuzuki, Associate Senior Vice President, NEC Corporation. "NEC is committed to working closely with its customers to increase their business efficiency and productivity with its IT/Network integrated solution, UNIVERGE, which we continue to promote globally."
