Live Meeting was convergence software (i.e., allowing integration with an audio conference). Using the web users could control PSTN lines (mute all parties except themselves, eject parties, etc.). User accounts were grouped together in Conference Centers (a unique URL) starting with: www.livemeeting.com/cc/. . . or www.placeware.com/cc/. . . Users could join a Live Meeting session free of charge. Charges for Live Meeting were on an account basis. Supply of accounts was mostly done by resellers (Global Telecoms companies) which levied per minute or monthly standing charges.
