Microsoft's NetMeeting is an Internet videoconferencing package. It can be used over the
local LAN, the Internet, ISDN, or over 14.4kbps+ modems. NetMeeting supports the
International Telecommunications Union (ITU) H.323 standard for audio and video
conferencing and can thus interoperate with other H.323 compliant software packages.
H.323 itself is a family of standards that define the transmission of audio and video. It
includes H.263 video, G.711 and G.723 audio codecs. NetMeeting also supports the
IETF's RTP/RTCP protocol which provides time stamping and synchronization control
for the audio flow.
