IVR: Screening & Recording with Python and Django

This is a summary of the provided text in one paragraph: A Django sample application models an IVR experience for stranded aliens trying to call an agent for instructions on how to get off Earth safely. The application uses Twilio's API to route calls, record voicemails, and send transcriptions to agents. Agents can screen calls, receive recordings of caller messages, and leave voicemails. The application provides a user-friendly interface for agents to interact with callers, including options for call screening, recording, and voicemail setup. The code is written in Python and uses Django as the web framework, Twilio's API for voice and SMS services, and various libraries for model management and data storage.
