Audio / Video chat (VoIP) Share Link with Jitsi Meet
Like this plugin here: http://forums.miranda-im.org/showthread.php?16437-MeBeam-plugin + the Option to enter an own Jitsi Meet Server.
It should generate link like http://meet.jit.si/MirandaIMSomethingRandom1234
Jitsi Meet is a great online audio/videochat platform which use webrtc and for the conference the XMPP Muc (in the background). It also supports multi audio/videoconferences.
