Creating a Click to Call Service with Twilio Client, Pusher and Python

A tutorial on creating a Click-to-Call service using Twilio Client and Pusher with Python and Flask, allowing customers to click a link and start an in-browser voice call with a human, while passing contextual information about the customer to the person handling the call. The service uses TwiML to generate instructions for Twilio to connect the caller to a specific user, and Pusher to publish events and update the backend view in real-time.
