Here is a summary of the provided text: Setting up a conference call line with Twilio Programmable Voice, Python, and Django requires several steps. First, create a free Twilio account and provision a phone number. Then, set up a Python virtual environment using virtualenv or similar tools, install Django and the Twilio Python helper library, and start a new Django project and app. Configure the project settings and files by adding the confline app to the installed apps list in settings.py and updating the allowed hosts list. Create URL routes and views for call logic, including dialing a conference line when a caller enters a valid PIN. Add a webhook to the Twilio phone number using ngrok to expose the local server to the public Internet. Once the basic conference line is set up, add view logic to secure the conference line by adding a PIN number and limiting the number of participants. Finally, customize the experience of the callers with an extremely robust API provided by Twilio's Conference feature.
