Oberg says the main attraction of Skype for corporations is savings. Calls between Skype peers is free, as is video and conference calling among Skype clients. The company charges for connecting calls to the traditional public phone network.Business benefits would also include better productivity. He says Skype uses a permanent video call between two of its offices that is displayed on a screen near water coolers in both offices. "We are changing the water-cooler conversation. We are making it international," he says.

Skype can be embedded in third-party applications to enable, for example,click to call support for Microsoft Outlook directories.
