WebHuddle’s Web Conferencing and Desktop Sharing solution has integrated Teleconferencing / Conference Calling via Lypp.
WebHuddle is an open source Web Conferencing & Desktop Sharing solution that works on both Mac & Windows. It is both free to download and use. For a limited time WebHuddle is offering free Teleconferencing via Lypp as well. WebHuddle + Lypp works rather well even though it is in early beta.
