Twilio Outbound call

I m facing a difficulty while retrieving the data from twilio…
I have used Twilio.Workflow.Activities to initiate the outbound call from Studio to call an IVR number and I am able to navigate through the options (Inputs like press 1 for English etc.) facing challenge while retrieving data from twilio like output in any form like speech to text or any form.
has anyone worked before.

Thanks in Advance…
