The Play activity enables IVR Routing to play messages or read back the contents of variables to callers. The Play activity can play a prompt or a single wave file to customers. For example, you can use a Play activity to greet callers and ask them to hold for the next available agent. You can add a new prompt to a Play activity, add a prompt that you have previously recorded, or add a variable to a prompt. For more information on configuring prompts in workflows, see "Configuring prompts".
The duration of a prompt is stored within the <<LastWavePlayedDuration>> system variable. This value will be overwritten any time a wave file is played in the workflow.
