Microsoft NetMeeting
（重定向自NetMeeting）
Microsoft NetMeeting was a VoIP and multi-point videoconferencing client included in many versions of Microsoft Windows (from Windows 95 OSR2 to Windows XP). It used the H.323 protocol for videoconferencing, and was interoperable with OpenH323-based clients such as Ekiga, OpenH323, and Internet Locator Service (ILS) as reflector. It also used a slightly modified version of the T.120 Protocol for whiteboarding, application sharing (or by extension, desktop sharing), and file transfers.
