Probably because crappy audio is received better than audio out of synch from the video. Having the "bad international languge dub" effect on conferencing is distracting as hell. For what it's worth voice over IP is essentially solved; tools like Mumble can have 1000s of people with top tier quality. I'm not sold at all on why you'd even want video, 90% of most business meetings (in my experience) are screen shares that could be communicated by just sending a link anyway. For personal calls use direct connect peer'd connection; in my experience all of the problems of video calling is going through the enabling server.
