Web telephone-calling company Skype on Wednesday unveiled new software with automatic click-to-call features designed to make shopping easier and that also encourages users to join group conversations.

Skype Chief Executive Niklas Zennstrom said in an interview that features in the new Skype 3.0 — available in a public test version starting on Wednesday — can help the company move beyond its dependence on communications revenue.

The company has said it expects $195 million in revenue, up 225 percent from $60 million it took in 2005.

“You are also going to see new services which are more targeted to e-commerce,” Zennstrom said.

Skype-calling software allows users to place free phone calls to other Skype users on computers. It also offers cut-rate prices for calls to conventional landline or mobile phone users from either computers or a new generation of Skype-ready phones now available worldwide.
