Read the simulation’s evidence

After a web or phone call ends, Egma reads its call record from Retell and adds it to the simulation. The transcript includes the tool calls Retell recorded, including calls to your real backend. Calls answered by a test mock are marked mocked. The voice recording captures what the simulated caller heard. Retell text mode has no stored call record for Egma to import. Egma records the complete API exchange it conducted, including the tool results Retell returns. Retell does not provide a separate native agent trace for text mode. If the agent’s record is incomplete, check that the ended call is available in Retell. Once missing evidence arrives in Egma, you can regrade the simulation.

Enable production monitoring

Follow Monitor a Retell agent to import production calls.

​
If a simulation cannot reach the agent

  • Check that you selected the Egma agent and connection IDs from egma/config.yaml in the run command.
  • Run connection discovery for that Egma agent to check the Retell binding.
  • For text mode, confirm that Retell manages the agent’s LLM or conversation flow. Use a web call for a custom-LLM agent.
  • Check any required dynamic variables and backend access. A connected agent can still fail if its startup context is missing.
