Conference services tend to be quite expensive, although they are substantially less than even limited amounts of travel. With rates that high, relatively small percentage savings can add up to quite a large sum. The greatest savings are available through choosing a lower-cost conference service. For high volume users, most services also offer volume discounts. These are available to anyone making calls on a monthly basis, and often have no minimum spending levels.
More substantial discounts require monthly minimums, with penalties for early termination.
