Call quality is not a single number you check once. It is a stream of measurements — MOS, jitter, latency, packet loss — that arrive while a call is active and that you need to inspect afterward. This sample puts that stream into a Flask dashboard with live SSE updates, SQL-backed history, and threshold alerting, all verifiable without a Telnyx account. I work with Telnyx.
