How to Test an AI Phone Assistant Before You Trust It

Here is the good news about this whole category of technology. Unlike most business software, you do not have to take anyone's word for anything. A phone assistant can be tested the exact way your customers will experience it. You pick up your phone, and you call it.

Any provider worth considering will let you trial the assistant, set up with your real venue details, before it ever answers a genuine customer. Insist on that. Then test it properly. Here is how I would do it, and it is genuinely how I suggest people test ours.

Round one: be a normal customer

Call and do the most ordinary things a caller does. Book a table for two tomorrow night. Ask what time you open on Sunday. Ask whether there are gluten free options. Ask if you can bring a dog.

You are listening for a few things. Does it answer promptly? Does it disclose that it is an AI and that the call may be recorded, without being asked? Does it understand you the first time, and confirm the booking details back before finishing? This round should be boring. If the assistant stumbles on the basics, you are done, and you have saved yourself a lot of grief.

Round two: be an awkward customer

Now make it harder, because real callers are not tidy. Ramble and change your mind mid-call. Talk over it and see whether it copes. Call from a noisy spot with the range hood on. Ask it something it should not know, like the chef's name, and check that it offers to take a message rather than inventing an answer. Be a bit short with it, not abusive, just impatient, and see if it stays calm.

You are not trying to prove the assistant is perfect. You are finding where its edges are, and how it behaves at those edges. An assistant that fails gracefully by taking a message is fine. An assistant that fails confidently, inventing answers or booking things it should not, is not safe to put in front of customers, no matter how natural its voice is.

Round three: check the paper trail

This is the round people skip, and it is the most important one.

• Check the booking actually landed. That table you booked in round one, is it in your system, on the right date, with the right name and number? A conversation that sounds perfect but writes down the wrong thing is the worst failure there is, because you will not catch it until a guest is standing in front of you.
• Check the messages arrived. For anything the assistant said it would pass on, did you get it, and would you actually notice it on a busy day?
• Listen back to the recordings. Every decent provider gives you access to call recordings or transcripts. Hear exactly what your guests will hear.

Round four: recruit fresh ears

You know too much. You know it is an AI and you unconsciously speak to it in ways it understands. So ask a few friends or family, ideally including someone older and sceptical, to ring up cold and book a table. Then ask them two questions: did you get what you called for, and how did it feel? Their answers will tell you more than any product demo.

Then start small

When you go live, you do not have to jump off a cliff. Start with overflow and after-hours only, so the assistant answers when your team cannot get to the phone and when you are closed. Review the recordings and bookings weekly, then expand only when the evidence says so. Any provider that pressures you to go all-in on day one is optimising for their onboarding numbers, not your risk.
