# Evidence and troubleshooting

## 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](/docs/platform/graders/configure-graders#regrade-a-simulation).

## Enable production monitoring

Follow [Monitor a Retell agent](/docs/integrations/retell/monitor) 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.
