An open source alternative to Skype is Project Gizmo, at http://www.theregister.co.uk/2005/07/05/project_gizmo_voip/

“Whereas Skype has selectively licensed usage of an API that offers limited insight into a closed protocol, a closed ecosystem solely controlled by one organization, the SIP protocol is open.
