*Disclaimer: MeetingSphere is not meant as a tool for mass communication. The number of concurrent participants supported in a meeting depends on the equipment and network infrastructure participants use. For example, participants joining without a headset or over a noisy line can force leaders to revert to "Mute all/Push-to-talk" early. Likewise, several participants sitting behind one slow firewall can spoil the screen sharing experience for these users. Moreover, events and conditions on the Internet which are outside MeetingSphere's control can affect the quality, in particular, of voice connections.
'Anytime sessions' to which participants contribute in their own time do not require a voice conference and will accept contributions from several hundred participants.
