China's no. 2 telecommunications carrier, China United Telecommunications Corporation (China Unicom) has selected Cisco Systems as the lead supplier in a multimillion U.S. dollar Voice-over-Internet-Protocol (VoIP) communications network.

CHINA - The nationwide VoIP communications network will span more than 319 cities across 30 provinces in the PRC. When complete, the network will rank as the world's largest VoIP network.

Under a multiphase contract, Cisco Systems will supply IP core backbone and aggregation routers and switches as well as voice applications for the packet-based network. China Unicom's network will be based around five major hub, with Beijing the centre, and Shanghai, Chengdu, Shenzhen and Guangzhou as supporting hubs.

According to telecommunications research firm Probe Research, China's VoIP services are expected to account for 15 - 20 percent of all packet-based telephony traffic carried worldwide by the year 2005. This is more than 60 billion voice minutes of an estimated 570 billion minutes carried annually over packet networks. Currently around 7.7 billion minutes of voice traffic are transmitted via packet networks each year.

"With the deregulation of the PRC's telecom market and the close proximity of full entry of China into the World Trade Organisation, China Unicom has great expectations for our VoIP network to provide easier and cheaper access to residential and corporate customers for both domestic and international usage," said Mr. Liu Yunjie, General Engineer and Vice President of China Unicom.

"The exploding rise of packet-based telephony networks in China and indeed, across the Asia Pacific region, can be attributed to a number of factors such as the deregulation of telecom networks, the carriers' need to deploy services quickly and cost effectively, and the dramatic improvements in quality and reliability of carrying voice over networks today," said Frankie Sum, managing director of Cisco Systems (HK) Limited.

"Asia is a market that has seen a dramatic increase in the convergence of data, voice and video over a single network which results in significant cost-savings for the carriers, and at the same time, giving customers the same carrier-class quality of service they would get from public switched telephone networks," he added.

Cisco will provide IP backbone core routers and aggregation routers including AS5800s, AS5300s Voice Gateways, 7200 Gatekeeper, Catalyst series switches as well as pre-paid and post-paid voice applications for the national network.

Cisco's China ecosystem partner, Netspeak, will be assisting in the installation of the IP infrastructure.
