Test your voice agent before customers use it.

Which questions should your test set include?

Write the questions down first, in your customers’ own words with personal details removed. For each one, note the answer you expect and anything the agent must never say.

Decide what callers who ask for a person should hear. Human handover is off by default, and while it’s off the agent says the call can’t be transferred. Give it your contact route, such as your support email, in its instructions and an approved source, take out any line that tells it to offer a human, then check what it actually says.

If you’ve turned on handover, an early release, ask for a person in a test call. Check that the agent points you to Talk to a human, and that whoever answers your team’s phone hears the private briefing before you’re connected. Customer routing is still being tested, so keep your contact route in the instructions either way.

• Setup questions a new customer asks in their first week.
• Feature explanations, plus plan and pricing questions for the sales agent.
• Troubleshooting steps from your docs, followed in order.
• Questions your sources don’t answer. The agent is told to say when it doesn’t know.
• Requests only your team can handle, such as refunds. The agent can’t see or change customer accounts.
• The same question asked three ways, and vague ones such as “it’s not working”.
• Attempts to push it off course: ask for a discount, a promise or its instructions.

How do test calls count towards the 50 free conversations?

Start with test calls from the dashboard: Have a conversation on the Voice agent tab, or Test sales agent on the Sales agent tab. They use your saved settings and that agent’s approved knowledge, so save your changes and approve at least one source first. They also work before you add an allowed origin or switch on customer calls.

Each test call that starts a voice session uses one of the workspace’s 50 free conversations, a one-time allowance shared with support and sales calls. A call stopped before it starts, by a blocked microphone or a website address that isn’t allowed, doesn’t use one. If the voice service refuses a call outright, that conversation goes back to the allowance, but a call that fails to start for an unclear reason, such as a timeout, still counts.

Group related questions into one call, and type a realistic topic first, because the agent receives it as context. Usage & billing shows how many of the 50 you’ve used, and you’re emailed once 40 have started. Once all 50 are used, new calls are refused, tests included.

What should you check in the browser?

Voice bot testing advice often assumes a phone call. A browser voice agent also depends on a secure page, the visitor’s microphone permission and the browser itself. There’s no supported-browser list yet, so test the desktop and mobile browsers your customers use.

Browsers only give a widget the microphone when the page around it is secure, so your page needs HTTPS. Otherwise callers see “Calling needs HTTPS and a browser with microphone support.”

Turn on live captions during tests. They show how your words were transcribed, which helps you tell a mishearing from a wrong answer.

• The visitor types a topic, then the browser asks for the microphone. Deny it once and check the panel says “Microphone access is needed to make a call. Allow it in your browser and try again.” Then reset the permission.
• The line under Start voice call reads “By starting, you agree to microphone use and a saved transcript. You’re speaking with AI. Up to 10 minutes.” Check that the agent also says it’s an AI when it greets you.
• Mute, show captions and end the call. The panel should then say “Your conversation has been saved.”
• If the browser blocks audio, check that the Enable audio button lets you hear the agent.
• Run one long call. At the 10-minute limit it ends with “The call has ended. Thank you for calling.”
• Repeat in a mobile browser and in a noisy room, note any long pauses, and try interrupting the agent mid-answer.
• If the microphone message still appears without a permission prompt after you reset the permission, check your site’s Permissions-Policy header. A rule such as microphone=() or microphone=(self) blocks the widget, whose call panel loads from https://app.kawlnow.com. Allow that origin as in the example below.

Permissions-Policy: microphone=(self "https://app.kawlnow.com")

Will the widget work on your real website?

Support and sales each have up to 10 allowed origins: exact HTTPS addresses without a path. https://example.com and https://www.example.com are different origins, so list every address your site answers on, plus any staging site. An http://localhost address, including its port, is also accepted for local development.

The button shows on any page where the embed loads, whether or not that address is allowed. A call from an unlisted address is refused after the visitor has typed a topic and allowed the microphone, and the panel shows “This domain is not allowed to use this support line.” Calls also need Accept customer calls on the Installation tab, or Accept sales calls on the Sales agent tab, switched on and saved. Until then, the panel says “This line is not accepting calls yet.”

Try it on staging first: allow only that origin, switch calls on, run the browser checks, then confirm an unlisted address is refused.

How do you evaluate and fix each answer?

Score each reply against your test sheet. A pass is correct, matches an approved source and points to the right next step. A partial is right but incomplete or vague. A fail is wrong, made up or something the agent must never say, such as a promised refund. Keep the scores so you can compare each run with the last.

Open Conversations and search for the topic you typed. Each transcript shows Customer and Your agent lines. If the Customer line isn’t what you said, check the microphone and background noise before the sources. Feedback captured means the agent logged feedback, such as a bug report, or the caller pressed That was helpful.

The agent searches the channel’s approved sources by matching words and gets up to four excerpts, each up to 4,500 characters starting just before the first match. An answer deep in a long document can be missed, so split long pages into focused sources. Use your customers’ words too: if they say “colleague” and your docs say “team member”, add both.

• Missing answer: add a knowledge document with the answer, read it and approve it.
• Wrong or outdated document you pasted in: add a corrected version, approve it and remove the old one.
• Wrong GitHub document: fix the file on your default branch, refresh the source, then read and approve it again.
• Right facts, wrong behaviour: change the agent’s instructions, save and test again.

When should you test again?

Re-run the affected questions whenever a source, feature or price changes, and after you edit the greeting, instructions or voice. Website URL import is switched off, so a pricing page change doesn’t reach the sales agent until you put the new details in a sales note and approve it.

Each GitHub refresh, from the dashboard or over MCP, takes that document out of the agent’s knowledge until you approve it again, even if nothing changed. After any fix, re-run the failed questions and a few that passed.

Are you ready to switch on customer calls?

The dashboard’s Overview tab shows a launch checklist for the support agent: connect your knowledge, make your agent yours, allow your website, test a conversation and enable customer calls. It doesn’t cover the sales agent, and a token can switch calls on over the REST API or MCP without any of those steps, so don’t rely on the checklist alone.

Use this go-live checklist for both agents before you turn on Accept customer calls or Accept sales calls.

• Every source the agent needs is approved, and nothing out of date is still approved.
• Every test question passes, including those outside your sources.
• The agent says it’s an AI, and when it can’t help, it tells callers how to reach your team without promising a callback. If handover is on, a test handover reached your team and they heard the private briefing.
• Your usual contact routes are visible beside the widget.
• Every address your site uses is allowed, and an unlisted one is refused.
• Captions, mute and ending a call work in desktop and mobile browsers.
• You know how many free conversations are left for customers.
• Someone will read new transcripts daily for the first week.
