The Busy Output Branch

If the Call Redirect step registers the destination extension as busy, the script executes the Busy output branch.

Configure the Busy output branch of the Call Redirect step to set the value of the prefixPrompt variable to inform the caller that the extension was busy.

The Busy output branch of the Call Redirect step contains the Set step. Configure the Busy output branch of the Call Redirect step by dragging a Set step from the General palette to the Design pane, and dropping it over the Busy icon under the Call Redirect step, as shown in figure Name To User—Yes Output Branch of Implicit Confirmation Step.

Then configure the Set step to set the value of prefixPrompt to contain a system prompt that will play back a message to the caller that the extension is busy when the script falls through to the final Play Prompt step (see The Call Redirect Step).
