According to reports in local media, the domain name system of China's leading VoIP service provider UUCall has recovered and its website reopened on February 4, 2010.

An insider said that after the DNS suspension of UUCall last year, the company relocated its domain name UUCall.com overseas. Currently, UUCall's official website is accessible.

Prior to this, the domain name services system of the website for UUCall broke and its services were closed on October 7, 2009. The sudden service closure reportedly affected 30 million registered users of this VoIP website. On that day, Hangzhou Youheng Network Technology Company, the operator of UUCall, reportedly received a notice from Zhejiang Communication Administration, stating that the company's operating of VoIP had violated China's regulations and should be closed for rectification.

Founded in 2004, UUCall has been developed into one of the largest VoIP brands in China. With the UUCall software, users can make low-cost calls on their computers to any telephone or mobile phone across the world.

With the rise of VoIP enterprises in 2005, the Chinese Ministry of Industry and Information Technology, which was then called Ministry of Information Industry, issued regulations to limit the entry of Chinese private capital into the operation of VoIP. This policy was mainly to protect the rights and interests of traditional telecom operators and showed worry about the communications quality and communications information security of Internet calls. However, with the rapid growth of Chinese netizens and the maturity of the VoIP technology, operating enterprises in this sector also developed.
