Test with a recording

Prove the key, the protocol, and the events with a file first. Ten minutes. No switch needed.

What you need

Python 3 and pip install websockets.

A mono 16-bit WAV at 8000 or 16000 Hz. A recording of a scam call works best.

The script

It streams the WAV at real-time pace and prints every event.

Run it:

What you should see

On a scam recording:

session.started ""
transcript.line "This is officer Smith from Social Security."
verdict {"score": 0.72, "level": "likely_scam", ...}
transcript.line "Pay the fine today with gift cards or you will be arrested."
verdict {"score": 0.94, "level": "scam", ...}
session.ended {"score": 0.94, "level": "scam", ...}

A clean recording prints session.started, some transcript.line events, and session.ended with "level": "clean". Zero verdict events on a clean call is normal.

If it fails

What you see	Cause
Upgrade refused with `401`	Wrong key.
Upgrade refused with `503`	`live_filter` is `false`. See Before you start.
`session.started` then nothing	The WAV is stereo, 8-bit, or silent.
Garbage in `transcript.line`	Wrong sample rate.

If this script works, the rest is switch configuration, not protocol work. Next: Connect your switch.
