Voice agent end-to-end testing drives a real call through the whole stack and judges the outcome and audio, not component scores. Here is how to do it.

The voice agent QA process runs from success criteria to production monitoring. See the four stages, artifacts, owners, and where evaluation fits.

A handoff loop is when a voice agent transfers a caller in circles without resolving. Learn how to test for, cap, and detect handoff loops before launch.

How to test for VAD misfire in voice agents: catch false triggers on noise and missed speech, build a noisy test set, and measure misfire rates.

Task success rate tracks whether the caller's goal got done. Containment rate tracks whether a human stayed out. Here is how the two diverge.

Voice agent containment vs resolution: containment counts calls kept from a human, resolution counts issues actually solved. Learn which to track first.

A voice agent KPI dashboard turns raw metrics into daily action. Learn what to include, how to lay it out by audience, and which vanity numbers to cut.

Voice agent metric thresholds turn metrics into pass/fail gates and alarms. Learn to baseline first, pick static or control limits, and act on breaches.

The north star metric for a voice agent is verified task success, the outcome the caller wanted. Learn how to choose it and set guardrails around it.
