Skype has announced its Skype for SIP capability that would make the link between its calls and corporate PBXs. Oberg was seeking cooperation to make interoperability easier for corporate customers. Skype has also issued Skype for Asterisk, which enables using Skype client software as softphones in businesses that use open-source Asterisk IP PBXs.

Oberg says the company is building a stable of channel partners who will sell Skype to businesses and also is developing a premium support service that businesses require in order to ensure uptime for their communications. That will include local tech support with staff that speaks the local language, he says.

The company is also working on a business control panel, software that will enable a business to buy Skype credit and distribute it among individual users within the business.
