I've cloned the repository, installed dependencies, gathered credentials, and set up a Twilio phone number to use with the Twitch phone call system. I have created an ngrok tunnel to expose the server to the internet, updated the phone number to point to the ngrok URL, and added the overlay to OBS using a flag to enable media stream access. Now, when I navigate to localhost:3000/dialpad, I can control whether to answer or end the call through websockets, allowing me to take calls on my Twitch streams live with Twilio's technology.
