1. Ekiga or GnomeMeeting
Ekiga (formely known as GnomeMeeting) is an open source SoftPhone, Video Conferencing and Instant Messenger application over the Internet.
It supports HD sound quality and video up to DVD size and quality.
It is interoperable with many other standard compliant softwares, hardwares and service providers as it uses both the major telephony standards (SIP and H.323).
Vat is an audio conferencing application developed by the Network Research Group of Lawrence Berkeley National Laboratory. Source code and pre-compiled binaries are available via anonymous ftp. Vat-related questions and feedback are welcome and can be sent to the developers via vat@ee.lbl.gov.
Vic is a video conferencing application developed by the Network Research Group at the Lawrence Berkeley National Laboratory in collaboration with the University of California, Berkeley. Source code and pre-compiled binaries are available via anonymous ftp. Vic-related questions and feedback are welcome and can be sent to the developers via vic@ee.lbl.gov.
Wb is an remote conferencing application for shared drawing developed by the Network Research Group of Lawrence Berkeley National Laboratory. Pre-compiled binaries are available via anonymous ftp. Wb-related questions and feedback are welcome and can be sent to the developers via wb@ee.lbl.gov.
RAT. The Robust Audio Tool (RAT) is a an open-source audio conferencing and streaming application that allows users to particpate in audio conferences over the internet. These can be between two participants directly, or between a group of participants on a common multicast group.
WBD is a shared whiteboard compatible with the LBL whiteboard.
NTE is a shared text editor designed for use on the Mbone. It is not a word processor (it is not clear that word processing is a useful task to share) and it is not a whiteboard - if you want a whiteboard, wb from LBL is a much better whiteboard.
4. NeVot
NeVot. The audio media agent. It obtains audio samples from the workstation and sends them as packets on attached networks. It also receives packets and plays the audio samples on the workstation audio device. Each instance of NeVoT can handle one or more audio conferences. nevot has a Tk user interface. nevotd is a daemon, without any graphical user interface, but the same capabilities as nevot.
5. IVS
IVS (INRIA Videoconferencing System) is one of the first software videoconferencing tool for the Internet (first version was available on July 92). IVS is a software system to transmit audio and video data over the Internet using standard workstation. It includes PCM and ADPCM audio codecs, as well as a H.261 codec. Both audio and video codecs are software codecs. Hence, only minimal hardware upgrades are required to a machine commonly found on the desk of an engineer, namely a video camera and a frame grabber.
