Name

NoOp() — Does nothing

Synopsis

    NoOp(text)

Does nothing—this application is simply a placeholder. As a side effect, the application evaluates text and prints the result to the Asterisk command-line interface, which can be useful for debugging.

Tip

You don’t have to place quotes around the text. If quotes are placed within the brackets, they will show up on the console.
