Test Your Voice Agent Right From the Browser

Iterating on a voice agent used to mean: edit the prompt, pick up your phone, dial the number, listen, hang up, repeat. We've eliminated that loop. You can now test-call your voice agent directly from the browser.

How it works

Open any voice agent's configuration page and click Test Call. A dialog opens, your mic activates, and you're talking to the agent — through your browser, in real time, just like a real caller would.

Pick the channel

Test the agent as if it's being called over a phone line or over WhatsApp calling. The agent behaves the way it would in production for that channel — so you're testing the real experience, not an approximation.

Optional customer context

You can attach a known customer to the test call, so the agent has the same context it would on a real inbound from that person — name, history, past conversations, qualification status. Test the "returning customer" flow without actually being that customer.

Live audio visualizers

The dialog shows two live audio visualizers — one for your voice, one for the agent's. You can see turn-taking happen in real time: when the agent is listening, when it's speaking, when it's processing.

Why it matters

Prompt engineering a voice agent is a tight feedback loop by nature — you need to hear the agent respond to judge whether your change worked. Test Call collapses that loop from minutes to seconds.
