There are several call back permutations. Call back subscribers are given a number which they call from anywhere in the world. This number could be a local number or an international number. The subscriber hangs up and the call back services literally calls back and allows the subscriber to make a call anywhere. Call back services can be restricted to only call specific numbers back.
Some services require a separate call back account for each number.
