register-twilio-test-audio

To register Twilio test audio, upload a mulaw-format audio file to an S3 bucket and update the AUDIO_FILES mapping in the twilio_place_call.py script to expose the new audio option for test calls.

Twilio test audio files require mulaw format audio at 8kHz, mono. The file must be uploaded to a publicly accessible S3 bucket before updating the registration mapping in the codebase.

Validate Twilio test audio by placing a test call and confirming the audio URL is accessible. The registration process updates the twilio_place_call.py mapping to ensure reliable delivery of the audio asset.

Twilio test audio registration is designed for local development and staging environments where new test audio options are needed. It is not intended for production usage based on the current implementation scope.

An S3 bucket with public access is needed for Twilio audio because Twilio must fetch the audio file via a public URL during the call. The registration process uploads the mulaw file to S3 and maps the URL in the codebase.
