China VoIP & Digital Telecom, Inc. Subsidiary Launches Systemwide Upgrade and Expansion Program.

Jinan Yinquan Technology Co., Ltd. Plans to Increase Server Capacity and Add Equipment in New Cities and Provinces to Accommodate Growing Demand for Its VoIP Services

HENDERSON, Nev. -- Citing growing demand for its voice over Internet services, Jinan Yinquan Technology Co., Ltd., a wholly owned subsidiary of China VoIP & Digital Telecom Inc. (OTCBB:CVDT), today announced it has launched a major, systemwide expansion program. The Company said it plans to significantly increase server capacity, add equipment in cities and provinces that are targeted for expansion, increase the number of available phone numbers, replace certain equipment to increase speed and efficiency as well as add additional staff at current and future locations.

Jinan Yinquan, a technology company offering VoIP services in the People's Republic of China, has been developing telecommunication solutions for China's burgeoning Internet industry for more than half a decade.

"Our mission is to become the premier provider of VoIP services in the People's Republic of China," said Li Kunwu, President and CEO of China VoIP & Digital Telecom Inc. "To accomplish that goal we need to always be several steps ahead of our growth so that we will never be in a position that we cannot adequately service our subscriber base. Therefore, we are adding two new servers to our current infrastructure, creating additional capacity for five hundred thousand new users (500,000). This brings our total infrastructure to twenty-seven (27) servers. All of our new servers will be installed in China Tie Tong's equipment room, who provide us with the necessary access to bandwidth, network infrastructure and E1 interface. Expansion programs such as this will be virtually ongoing."

Jinan Yinquan's proprietary NP Soft Switch IP telephone system enables users to access Voice over the Internet Protocol (VoIP) services allowing customers to use the system to make telephone calls to anyone in the world at a much lower cost than standard telephone rates.

Jinan Yinquan currently services three provinces and 19 cities with Shandong Province its primary base of operations. Short- and long-term plans call for the expansion throughout China.

Jinan Yinquan recently announced a cooperative venture with one of China's premier licensed telecom providers, China Tie Tong, one of only six licensed providers in the country. This effort will allow the Company to rapidly deploy its VoIP technology throughout the world's most populous country.

The ability to increase telephone number capacity will be provided through China Tie Tong. In turn, Jinan Yinquan will route all calls through Tie Tong's extensive network and backbone.

China Tie Tong is one of the six largest basic telecom operators in China. The company, which has 31 provincial branches and 316 municipal branches, employs approximately 72,000 people. Its high-speed backbone optical transmission network consists of five fiber loops covering most of the cities in China's 31 provinces and a distance of 52,000 kilometers. During the period of 2001 to 2005, annual revenues have grown by 30 percent while fixed-line subscribers increased from 1.35 million to 16.4 million. By the end of 2005 the company had 2 million Internet subscribers and assets of 53.3 billion RMB. (For more information, go to www.chinatietong.com.)
