Test-calling Milo before going live

Key takeaway

Test calls let you experience exactly what your callers will hear — free of charge — so you can tune your script and voice before real customers call.

Why test-call?

Reading your script on a screen and actually hearing Milo speak it back are two very different experiences. A word that looks fine in text might sound awkward when spoken aloud. A question you thought was clear might trip the AI up. Test calls catch all of this before it affects a real customer.

Test-calling is also the fastest feedback loop: you make a change, call again, and hear the result immediately. There's no deploy, no waiting.

How to start a test call

  1. 1

    Open your receptionist

    Go to Receptionists in the left sidebar and click on the receptionist you want to test.

  2. 2

    Click 'Test call'

    You'll see a Test call button in the top-right of the receptionist detail page. Click it.

  3. 3

    Pick how you want to connect

    You can either call the number from your phone or use the in-browser dialler — both work. The in-browser option is faster if you're sitting at your desk.

  4. 4

    Have a conversation

    Talk to Milo the way a real customer would. Ask about your hours, try to book an appointment, test an edge case. Make it messy — that's the point.

After each test call, go back to your script, make one or two adjustments, and immediately call again. Small iterations work better than one big rewrite — you can hear the impact of each change.

What gets used

During a test call, Milo uses the real script, the real voice, and the real knowledge base you've set up. If you've connected Google Calendar, Milo will even check your actual availability. This means a test call is as realistic as it gets.

What doesn't count

Test calls do not consume your prepaid call balance. You can make as many test calls as you like without worrying about your credit. The only thing that counts against your balance is genuine inbound calls from callers outside your account.

If you're using the in-browser dialler, audio quality depends on your microphone and internet connection. If Milo seems to mishear you, try your phone instead — it gives a more realistic signal and better reflects what real callers will experience.
