You may also be calling an auto-forwarding telephone number, which has a certain number of "paths" (connections) to some remote collection of modems. These are charged (to the operator) on a per-path basis or otherwise. They can be used to good advantage where there isn't sufficient demand to justify setting up a POP as defined last week in NetBITS.
