I use Eagle Teleconferencing services for all my conference calls and I could not be happier with them. They have several different options for service so you can chose whichever suits your needs best. Personally I chose the option of having my own 24/7 line. That means I use the same dial in number and pin numbers anytime I need a conference call. I never have to call in and make a reservation, my call is already set up. This would not be best for some people, so they also have the options where you can call in to make a reservation anytime you need a call, and they can give you different pin numbers and dial in numbers. What ever your needs are, Eagle Teleconferencing has something for you!!!!
