A company can use Twilio Studio, a visual workflow builder, to create an IVR (Interactive Voice Response) hotline that collects customer feedback. The process involves creating a new flow, assigning a phone number, and adding widgets such as "Say/Play" and "Gather Input On Call". The flow is then configured to pass the call to an agent, bring in logic checks, and connect to a subflow for the survey. Once the survey is completed, a message can be sent via SMS to thank the customer for their time. Additionally, Twilio Serverless functions can be used to automatically call back customers who disconnect before taking the survey. The entire flow can be tested by pulling out the phone number and testing it.
