Twilio offers various channels for connecting with customers, and collecting individual words or numbers can be straightforward. However, when asking customers to share specific times and dates, such as scheduling an appointment, it can be complex. This blog post shows how to extract times and dates during a phone call using JavaScript and serverless Twilio Functions without the need for any third-party integrations. To build this solution, you'll need a free Twilio account, an active phone number with voice capabilities, basic Node.js knowledge, and create Twilio Functions to handle incoming calls, process user input, and convert it to a format that can be used in backend systems. The functions will use JavaScript packages like chrono-node and date-fns to extract dates from user input and provide a human-readable format. Once deployed, you'll need to connect the functions to your phone number, save both functions, deploy them, and try out the solution by calling the number and speaking a free-form time and date. This project can be used as a bare-bones example and extended to fit various use cases, such as connecting to backend systems or defining endpoints for handling incoming calls.
