Free Reservationless Conferencing Calls

My Company is doing a trial of www.freeconferencecall.com. They provide free conference services of up to 96 participants per call. There is a full list of features here. Since many of our home office employees have unlimited phone plans (i.e. no long-distance charges), I think this will work well. If we need a toll-free call-in number, the pricing is $0.06/minute/user...still very fair. They even include free recording...on our current service, we pay a flat rate of $15 for any recording (same rate if it is a 2 minutes or 2 hours). Will post again soon with the results of our trial!
