1.3   How a flowchart works

Each box has a name, and a set of conditions. You can add your own conditions - more about that in a later topic.

A flowchart is displayed as a number of boxes, joined together with lines. Each line joins a box condition to another box.

When SQLphone runs a flowchart, it runs each box in turn. To run a single box, SQLphone performs the action which is setup for the box. The action depends on the box type (playing prompts, collecting digits, executing a SQL statement, etc).

After SQLphone has run a box, the box's conditions are evaluated in top-to-bottom order (except the tries counter condition, which is evaluated before the box is run).

If a condition is true:

• SQLphone hangs-up if the condition does not have a line joining to another box
• Otherwise, SQLphone proceeds to run the box which is joined to the condition
