The On Exception Goto Step

Begin the Successful output branch of the Place Call step by dragging an On Exception Goto step from the General palette to the Successful icon under the Place Call step under the True icon under the If step in the Design pane.

Then configure the On Exception Goto step to send the script to the Label named LABEL0 if the script generates a ContactInactiveException.

The script throws this exception if the Contact becomes inactive. In this event, the script skips the Play Prompt step and the Terminate step, and goes to the Clear Exception Step described below.
