Exception Handler Block

Provides an alternate branch that the Voice application can execute if an exception or block error occurs. This lets the Voice application continue executing instead of exiting as it normally does. Use this block in any part of a Voice application in which you expect exceptions or block errors.

Conditional Exits

The Exception Handler block has two conditional exits: Try and Catch.

•Try - Enter the sequence of blocks that you predict might generate an exception or block error.

•Catch - Enter the sequence of blocks that you want the Voice application to execute if an exception or block error occurs during the Try conditional exit.

The block initially executes the Try conditional exit.

•If an exception or block error occurs while executing any block in the Try conditional exit, the Voice application executes the Catch conditional exit. After executing the Catch conditional exit, the Voice application executes the next block in the flowchart.

•If no exception or block error occurs, the Voice application does not execute the Catch conditional exit, and instead processes the next block in the flowchart.

After executing, the Exception Handler block stores one of the following values in the Exception interaction property:

•Error - A block error or exception occurred.

•No - No exception occurred (normal processing).
