We want to organize a conference with between 20 ad 30 participants, it could be full video conference, full audio, or let's say 1 or 2 video stream from the organizers and the rest would have audio.
We would have liked to use google hangout but the limit is 10.
Which solutions would you suggest? Preferably free, or up to 10 or 20$ per month only for the organizer (free for the participants). Somethings stable and simple too.
