FreeConference.com

A great dial-in teleconferencing solution for free. You just set up your call as little as 90 minutes in advance and distribute the call-in number to the folks calling. The organizer pays nothing, and participants pay only their usual long distance, which should be extremely cheap (particularly with the new flat-rate plans). The voice quality has always been excellent. In six months of use this teleconference service has never failed me one iota. I skip the bells and whistle services they offer. Since they don’t charge anything on your phone bill, or take your credit card number for their free service, they hope to make money on premium services, or maybe by selling ads in the future.

Anyway you can’t go wrong with this one.
