INTERACTIVE PLAYGROUND / NO REAL CALLS
Make mistakes
before they cost money.
Inspect how an agent handles answered calls, failures, and termination. Run a self-contained browser simulation. The separately downloadable Python Peer Lab does not run in this web page.
CALL WORKSPACE
One simulated call. Every event.
This simulation is scripted locally. It does not contact a telephone network, model provider, or payment system.
Event stream
- ⌁Run a scenario to inspect its lifecycle.
Agent-reported outcomes are not independently verified facts.

The standalone public Peer Lab runs locally through Python. The playground on this page is completely scripted and does not connect to that lab. Neither the Peer Lab nor this public website provides PSTN service.
Set up the local peer lab →What this proves
Illustrative state transitions, event sequencing, and the difference between an agent claim and external evidence. Not voice quality or carrier reachability.
