TELECOMMUNICATIONS  TECHNOLOGY  PROMPTS COMPANY TO EXPAND MARKETING EFFORTS

and Liao Ning Province

                                     - - - -

HENDERSON,  NV, December 6, 2006 - - - As the result of rapid  acceptance of its
proprietary  NP Soft Switch IP telephone  system,  China VoIP & Digital  Telecom
Inc.  (OTCBB:CVDT)  through  its new  wholly  owned  subsidiary,  Jinan  Yinquan
Technology  Co., Ltd.,  has added two additional  cities in two new provinces to
the ongoing  marketing of the system. 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,  a technology  company  offering  VoIP  services in the People's
Republic of China, has been developing  telecommunications solutions for China's
burgeoning Internet industry for more than half a decade.

The  Company  said the  system,  which  provides  users to  access  high-quality
broadband  telephone  services in China by  converting  a  customers'  cable/dsl
router into a VoIP device, is now available in TaiYuan,  in Shan Xi Province and
ShenYeng in Liao Ning Province.  There are 33 million people in Shan Xi province
and 42 million in Liao Ning.  The  population  of  Shandong  is 90 million  with
approximately 10 million Internet users.

"This will bring to 19 the  number of cities and our first  outside of  Shandong
Province  where our system is  available,"  said Li Kunwu,  President and CEO of
China VoIP & Digital Telecom Inc. "We are extremely encouraged by the acceptance
of the NP Soft Switch IP telephone  system  which has prompted us to  accelerate
our  marketing  efforts to areas  outside  of our core  Shandong  Province  core
market.

"The estimated  number of Internet users in China is less than 10 percent of the
total  population  of 1.3 billion  people,"  said Kunwu.  "However,  that number
continues  to grow  exponentially  as the economy  booms and  affordable  access
becomes  more  readily  available.  Combine  this with the  growing  demand  for
quality,  affordable  phone  service and it  squarely  places our Company in the
enviable position to become a provider of telecommunications solutions using the
Internet."

Jinan Yinquan's proprietary NP Soft Switch IP phone system is based on real-time
Internet communications technology and related applications. It uses software to
simulate circuit  switching and as a result,  provides networks call control and
connection control networks.

"Less than 25 percent of China's  total  population  is  landline  subscribers,"
Kunwu added.  "This is due in part to availability and cost. But the convergence
of accessible,  economical  high-speed  Internet  service and an affordable VoIP
service such as our NP Soft Switch System  creates a very exciting  scenario for
the growth of our company."

Kunwu said the Company's  future plans call for the expansion  into all of China
with its current and future products and services.

the  Company's  8K filing of November  13, 2006 on the  Securities  and Exchange
