Skype is to offer new features for businesses but it won't develop a specific voice-over-IP product for the workplace, Niklas Zennstrom, founder and chief executive of the company has said.

Skype already has some capabilities geared toward business users, such as a feature that lets multiple users share an account to pay for services.

Some of the partnerships Skype has, with companies like headset maker Plantronics and others, are also geared toward business users, Zennstrom said.

"We will continue to bring out features useful to business users. What we've not done is an enterprise-wide solution, and that's not our intention," he said.

About 30 percent of Skype's customers use the service for business, he said.

Questions about security have led some businesses to ban Skype, and some vendors even offer applications to block it. The company is trying to do a better job communicating about its security, Zennstrom said.

Some companies ban Skype because they don't understand that calls are encrypted and quite secure, according to Zennstrom. Oxford University in the U.K. banned it, but when Skype contacted the university and explained how the security behind it works, Oxford lifted the ban, he claimed.

Skype could become increasingly useful to business users who want to cut down on mobile phone calls. Skype already works on Windows Mobile devices, and the company continues to develop a Skype client compatible with Symbian, the operating system that fuels Nokia smartphones, Zennstrom said.

Only 4 percent of broadband subscribers in the U.S. are registered Skype users, the CEO said. He hopes the world will follow some of the Scandinavian countries, which tend to be early adopters and avid users of technologies like mobile telecommunications and broadband.

A fifth of broadband users in Finland are registered Skype users, and in Sweden 17 percent are registered Skype users, he said.
