Use the web preview to test a draft agent through your browser microphone or text chat. A simulated call lets you check the conversation without assigning a phone number.

​
Start a simulated call

1

Open a draft

Open Agents, select an agent, and make the draft you want to test active in the builder.
2

Set test variables

In the preview, enter values for any dynamic variables the agent expects. Use test data only.
3

Start talking

Select Start talking and allow microphone access when your browser asks. For a text-only test, select Start chatting instead.
4

Exercise the call

Test the expected path, missing information, interruptions, silence, and requests that should invoke an action.

​
What to verify

  • The greeting matches the call direction and opening mode.
  • The agent asks one clear question at a time.
  • Knowledge answers stay grounded in the connected sources.
  • Actions receive the required values and handle failures safely.
  • Transfers and call endings happen only under the intended conditions.
  • The agent responds correctly when a caller interrupts or pauses.
Change the prompt, flow, knowledge, or settings when a test fails. Start a new simulated call after each meaningful change.
Test with several speakers and audio environments. A successful happy-path call does not cover interruptions, background noise, or ambiguous answers.

​
Before you publish

Confirm that the draft passes your expected path and important failure paths. Then publish the version and assign it to a deployment path.
