One of the options is to Optimize Room Bandwidth. Should participants optimize their bandwidth according to their computer or host computer?
The bandwidth should be set according to the slowest speed a participant in the meeting is connect at. Connect will then compress the files so that all users have the same meeting experience. So, for example, if the host and 12 participants in the room have LAN connections and one person is on a modem the meeting room would be set to modem.
