China Tie Tong to Offer China VoIP & Digital Telecom, Inc. Subsidiary Products in Markets Outside of China Tie Tong's Metropolitan Area Network ('MAN').

Cooperative Venture Provides Additional Sales Channels for Jinan Yinquan Technology Co., Ltd.'s VoIP Business -- Paves Way for Low-Cost Expansion for Tie Tong 

HENDERSON, Nev. -- As further evidence of the growing relationship between Jinan Yinquan Technology Co., Ltd., a wholly owned subsidiary of China VoIP & Digital Telecom Inc. (OTCBB:CVDT) and China Tie Tong, one of the six largest basic telecom operators in China, the two companies announced today that they plan to enter into another joint venture project. The plan calls for China Tie Tong to install Jinan Yinquan VoIP products where Tie Tong networks are not available.

"China Tie Tong will promote our VoIP telephones in areas without Tie Tong's Metropolitan Area Network (MAN)," said Li Kunwu, President and CEO of China VoIP & Digital Telecom Inc. "The beauty of our proprietary Soft Switch technology is that existing Internet users can be developed into VoIP landline users of Tie Tong, even if the MAN is not installed."

Kunwu said the cooperative venture will bring Jinan Yinquan yet another sales channel for its VoIP business and indicated that this represents a "win win" situation for both companies.

"While we get an additional sales channel for our VoIP products and since the 'fix' lines in the areas in question are mainly installed and serviced by other telecom companies, this joint effort will enable Tie Tong to penetrate these markets without the significant costs associated with developing a landline infrastructure," said Kunwu. "Not only is it keeping with Tie Tongs' diversification strategy but it provides both companies with the opportunity to offer more convenient and lower-cost services to our respective customers."

Jinan Yinquan currently services three provinces and 19 cities with Shandong Province its primary base of operations. The Company recently announced it will expand to both Shanghai and Beijing and plans further expansion throughout China.

The Company'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.

China Tie Tong has 31 provincial branches and 316 municipal branches. They employ 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)
