(Nasdaq: WEBX), the leading provider of web communications services, today launched a new version of its award-winning WebEx Training Center service that allows companies to transform corporate training programs into strategic lines of business. With its new integrated e-commerce system, advanced tracking and reporting capabilities and automated resource planning, the latest WebEx Training Center service helps companies decrease the cost of delivering training and create new revenue opportunities through fee-based training programs.

"The market for live online e-learning is expanding as corporate customers look for integrated services that include multimedia communications, e-commerce, learner tracking, simulation labs and enterprise administration," said Josh Bersin, principal, Bersin and Associates, a noted authority on implementation and best-practices in corporate e-learning. "The new WebEx Training Center sets a new standard for integrated online training services."

WebEx Training Center’s new e-commerce capabilities enable training departments to allocate costs across the organization or convert programs into new business opportunities by delivering premium online training to customers and partners. The e-commerce system allows attendees to use employee or customer account numbers, credit card information and even training coupons for bundled or discounted training offers.

The new WebEx Training Center service supports continuous learning so trainers can develop programs that mix on-demand learning, interactive online classroom instruction and individual tutoring with remote access to centralized computer lab. The new integrated resource planning capabilities makes tracking and managing resources including trainers, online training materials, and physical resources simple and efficient.

"The new WebEx Training Center offers integrated e-commerce capabilities to help training organizations effectively align programs to measurable business objectives," said Min Zhu, president and CTO, WebEx Communications.
