How to test an AI voice agent before it takes real calls

InfiVoice ยท 2026-11-14

The best time to find a problem with your voice agent is before a customer does. A focused hour of test calls catches most of them.

Step 1. Write down what a good call looks like

List the three or four things the agent must do: answer, understand why the person called, book or capture details, and hand off when needed. Every test call gets judged against that list.

Step 2. Call it like your callers do

Use your own phone, not a test console. Ask the questions your callers ask most. Book an appointment, change it, ask for opening hours, ask about prices. Listen to the pace, the greeting and how natural it sounds.

Step 3. Try the awkward calls

Interrupt the agent. Mumble. Change your mind halfway. Ask something it should not know. A good setup answers from your knowledge base and says so plainly when it does not have the answer.

Step 4. Test the handoff

Ask for a person. Describe an urgent situation. Confirm the call goes where you expect and that the details collected so far reach the human.

Step 5. Check what happens after the call

Review the call transcript. Make sure the appointment and the lead details ended up wherever your team expects them.

Step 6. Test outside opening hours

Call at night and on a weekend. After-hours behavior is often where an agent helps most, so it deserves its own test.

Step 7. Fix, retest, then go live gradually

Adjust the prompt, knowledge base or flow, then repeat the failed calls. A common approach is to forward only overflow or after-hours calls first, then widen once you trust it.

What it costs to test

InfiVoice bills in credits, and one credit equals 60 seconds of call time. The Free plan includes 100 credits, enough for a round of test calls. Pro costs $79 per month with 250 credits.

Frequently asked questions

How many test calls are enough?

Enough to cover each call type you expect, plus a handful of awkward ones. Retest after every change.

Should someone else test it?

Yes. A colleague who did not build the flow will ask things you would never think to.

Can I keep improving it after launch?

Yes. Review transcripts regularly and update the knowledge base and flow as you learn.
