Touch tone key not available
I got an error “Touch tone key not available from parent element”. What does it mean and how can I correct that?
This error means that a child element/node specifies a touch tone key but the parent element does not expect a touch tone key. We’ll explain this through an example. Suppose you want to play a message, press 1 to record message, and press 2 to transfer call. You need to have a call flow like the following:
1. a Choice element (parent element P), and
2. a Record element (child element of P), and
3. a Transfer element (child element of P)
You specify the audio message as a prompt for P. At the end of your audio message, prompt a caller to press 1 and press2. The Choice element plays the prompt and waits for the touch tone key. The touch tone keys are specified on the child elements, 1 for the Record element and 2 for the Transfer element. You specify the key in the box labeled “touch tone key response is”.
The error normally happens when you use a wrong type for the parent element, such as a Prompt element. The difference is that the prompt element only plays the audio message. It does not wait for touch tone key responses.
