Decision

With this Step, you are able to direct the Call Flow based on choices the caller makes. Click on the Options icon, and there you can manage the logic that directs the step's decision making.
You can add criteria with the "Add Criteria" button. In addition, you can specify whether all criteria has to be met by one or more values. Do this with the dropdown menu located on the top left.
For each set of criteria, you must also specify an exit point that will be used when the values are met. You can specify this in the textfield located in the top right corner of the window.
Within each criteria, you can specify the conditional operator to use via the dropdown in the middle. In particular, the "Exists?" operator only checks for the existance of any variable you enter in the left field. That is, it will not evaluate or consider the value of the variable.
