China Tie Tong's Shandong Branch to Utilize Jinan Yinquan Technology Co., Ltd. Voice-over Internet Protocol Products for Trans-Regional Operations

HENDERSON, Nev. -- China Tie Tong's Shandong Branch, has turned to Jinan Yinquan Technology Co., Ltd., a wholly owned subsidiary of China VoIP & Digital Telecom Inc. (OTCBB:CVDT) to help launch its entry into the trans-regional VoIP call center market. According to China VoIP, China Tie Tong's Shandong Branch will use Jinan's proprietary Voice-over Internet Protocol (VoIP) products to equip the new ventures.

"The traditional method of setting up a call center telecom system is to utilize time-division multiplexing (TDM) which is a method of putting multiple data streams in a single signal," said Li Kunwu, President and CEO of China VoIP & Digital Telecom Inc., "Unfortunately, this is restricted by transmission resources which can only be used in a local area. Our VoIP call center solution will not only reduce costs but provide much greater function capacity."

"The strong functions and advanced technology of our system enables businesses to lower the cost of establishing a call center while greatly increasing its working efficiency and enlarging the business scale for the enterprise," said Kunwu. "The fact that one of China's leading telecom providers has selected our system to launch its call center initiative is further validation of the strength of our technology."

Jinan Yinquan now 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.
