I just used this website to setup a free conference call. It was really smooth. These people at Free Conference know what they are doing. They have 3 different accounts, one for toll-free calls which gets expensive, a free registered account where you can reserve times, and an unregistered account where you can just get a conference started at any time if its available. I used it to arrange a call between a couple people to talk about a real estate deal and it worked perfectly. The only catch to this deal is that the conference call number is likely long-distance for you. However with free and unlimited long distance, this becomes a non-issue. It has a web-based interface where you can control many aspects of the call and see who has called in. It also gives you features like muting and conducting a question and answer session call. Pretty cool stuff for nothing. Thought this would be a good tool for most business people.
