Test calls let you hear what your agent actually sounds like before any real customer does. Run a few before you publish to catch issues early.
1

Insert a number as a test contact

Test calls always go to a contact, so add the number you want to test with (usually your own) as a new contact in the Contacts page first.
2

Open the test call dialog and place the call

In the agent builder, click Test call to open the dialog. Pick the agent version (your draft with unsaved changes or any saved revision) and the contact to call (their properties get substituted into your variables). Use the arrow next to the call button to choose how to call: Phone Call has the agent dial the contact’s phone from the outgoing phone number you pick, while Web Call lets you talk to the agent right in the browser with your microphone and follow the transcript live. Then click Call Phone or Web Call to start the test.If your plan does not include outbound calls, a Phone Call can only reach numbers verified by a member of your account, such as the number you signed up with. Without a plan, you get five connected test calls.During a Duo test call, you can guide the agent with silent notes, spoken notes, or instructions below the live transcript, in both phone and browser calls.
A few habits that pay off: always test your draft version before publishing, use a real contact so your variables get filled in, and run a few different scenarios (both the typical conversation and the unusual ones).
