The Call Configuration application is used to:

Setup Call Profiles - Call Profiles are used to specify the time at which Remote Units begin to call in, the interval between the Daily Call Windows, and the spacing between the Remote Units in the Daily Call Window.
Setup the Call Schedule - The Call Schedule is calculated from the user-specified Call Profile data. After the Call Schedule is calculated you can view it and make necessary changes, such as excluding a Remote Unit from the schedule or changing a Remote Unit's new call in time.
