# 4. Test your agent

Before real callers reach your agent, **talk to it yourself in the browser.** Test calls run
in a live session but are **not logged** — no call record, no recording, no cost — so you can
iterate freely on the greeting, prompt, and voice.

<Steps>

### Start a test

Open the agent and use **Test "&lt;agent&gt;"** to start an in-browser conversation. Your
microphone connects straight to the agent, exactly as a phone caller would hear it.

### Listen for the essentials

- Does it **greet first** (you should hear it speak as soon as the session starts)?
- Is the **voice** right for your brand and language?
- Does it **collect the fields** you defined and **follow the prompt**?
- Do your **tools** and **transfer** behave as expected?

<Callout type="info">
A test call won't appear in [**Call logs**](/vio/call-logs) and won't accrue cost — that's by
design. To see a real call log with transcript, recording, and cost, place an actual call to
your connected number.
</Callout>

### Fix and re-test

Edit the [**Persona & prompt**](/vio/agents/persona) or swap the
[**voice**](/vio/agents/engines-and-voices), save, and test again. The prompt generator's
**Improve prompt** is a quick way to refine wording without rewriting from scratch.

### Go live

When it sounds right, you're done — inbound calls to the assigned number are already being
answered. To reach out proactively, build an [**outbound
campaign**](/vio/telephony/outbound-campaigns).
