The structure of a dialog flow

A dialog flow is built by selecting and configuring pre-defined components and connecting them
together in a call flow. There are three main types of component:

dialogs

processes

and

rules

. An

instance of a component is called a

step

Figure 1. The different step icons (left to right): dialog, process, rule and Begin Dialog step

When you create a new dialog flow (see page 34), SAB automatically creates a

Begin Dialog

step

and an

End Dialog

step.

Figure 2. The Dialog Modeler window showing the Begin Dialog step (orange) and the three

types of component: dialogs (blue), processes (yellow), and rules (black diamonds)
