Is there a way to be notified if a voice agent doesn't work somehow like maybe a email notification or something or is the only way looking at call logs. Because we just had 2 ai agents suddenly stop working yesterday saying tool cant be found for some reason. there was no way to be notified unless we go in an manually call the agent to ensure its working everyday.

yes

Use webhooks like, on tool‑fail or call‑error events, integrate them with email/SMS/Slack notifications, and optionally add scheduled test‑call health checks so you don’t have to monitor logs manually..

There is no tool‑fail server event, where did you get this from? I want to get notified to the server url or simply run a tool if a tool call return something other ran 200 code.
