Twilio Studio IVR 呼叫在收集用户输入之前断开

Question

I am setting up an IVR flow in Twilio Studio. I have a function that validates the user's phone number and then fetches some data. Once the data is fetched, I need to ask the user to input their zip code. I have used the "Gather Input On Call" widget. But the call gets disconnected as soon as the flow reaches this widget (event hangup is triggered).

Any idea what I could be missing? Is it possible to gather multiple digits as User Input in IVR flow?

If you use a Run Function Widget and want to return TwiML, you should use a TwiML redirect widget to call the Function instead, then use the suggested syntax below to return to the Studio flow.

Returning Control to Studio

To handle returning control to Studio, you need to specify a to the Studio Webhook URL and append?FlowEvent=return. Any additional parameters specified in the return URL will be injected into the Studio context and addressable via Liquid template variables.
