When your AI should hand the call to a human

The best thing an AI receptionist can know is the edge of its own job. Everything inside the edge, it handles. Everything outside, it hands to a person, quickly and without making the caller fight for it. Get that boundary right and the desk earns trust. Get it wrong in either direction and it costs you: too eager and every call ends up on your phone anyway; too stubborn and a customer spends five minutes arguing with software.

Here is where we think the line sits, and how Vestibo draws it.

The caller asks. That is the whole trigger.

Start with the simplest rule. If a caller asks for a person, they get a person. Not after one more question, not after "let me see if I can help with that". Now.

On a Vestibo call, pressing 0 or saying "human", "person" or "owner" dials the phone number you gave for handoffs before the desk does anything else. It does not try to talk the caller out of it. Somebody who asks for a human has already decided the software is not what they need, and every second spent persuading them otherwise is a second spent losing them.

The caller is frustrated

People do not always ask. They sigh, they repeat themselves, they answer a question with a sharper version of the question they already asked. A receptionist that cannot read that will keep cheerfully offering the same three options while the caller's opinion of your business drops.

Vestibo's desk is built to offer a person the moment a caller sounds frustrated, and after it has failed to help twice. The offer comes first, before any attempt to take a message. That order matters. "Can I have someone call you back?" said early feels like service. Said after the fourth failed attempt, it feels like being fobbed off.

The request is outside the desk's brief

Every trade has questions the front desk must not answer. Whether the caller has a legal case. Whether a symptom sounds serious. What to do about a notice from the tax office. Whether a particular repair is safe to drive on until Monday.

The right response is a polite refusal and a handoff, and it should be the same every time. Vestibo's templates carry these boundaries for each trade so the desk declines consistently, and its knowledge is limited to what you gave it about your business. It does not improvise an answer to a question it was never meant to take. When you set it up, add your own list: the things you personally never say on the phone. Those become handoffs too.

The stakes are high for the caller

Some calls are urgent for the person making them even when nothing about the words is unusual. A customer locked out. A pipe that has been leaking since midnight. Someone in pain asking for the first available anything.

A receptionist should recognise urgency and get a person involved, not because it cannot book the appointment, but because the caller needs to hear that a human knows. Templates for trades with emergencies are written to escalate them. If your business has an emergency line or an on-call arrangement, give the desk that number and tell it when to use it.

The desk does not know, and knows it does not know

This is the quiet one. A caller asks something reasonable that you never told the desk. The wrong move is to guess. The right move is to say so, offer to have a person follow up, and take a name and number.

Then the fix is yours: add the answer to the Knowledge tab and the next caller gets it. Read your transcripts in the first weeks and you will find these gaps quickly. Each one is a one-minute edit.

What a handoff should actually do

"Transfers to a human" is easy to print on a features page. Ask what happens mechanically, because the details decide whether the caller is helped or stranded:

1. Does it ring a real phone? Vestibo dials the handoff number you set. Make it a phone somebody carries, not a desk line in an empty office.
2. What if nobody answers? The desk takes the caller's name and best number, tells them a person will be in touch, and alerts you at once, in the dashboard and by email. The caller is never left in silence or bounced back into the same conversation.
3. What if the handoff number is the one the call came from? This happens when an owner forwards their own cell to the desk and then lists that cell as the handoff. Dialling it would send the call straight back to the software. Vestibo detects that case and takes a message instead of looping.
4. Does it try more than once? Repeated dial attempts on one call are a good way to keep a caller waiting. Vestibo bounds them.
5. Do you find out? Every handoff and every message is in your inbox with the transcript of what led up to it, so when you call back you already know why they rang.

If a vendor cannot answer those five, the feature is a sentence, not a behaviour.

What should not trigger a handoff

Being clear about the edge means being clear about both sides. A receptionist that hands off too readily is a receptionist you have to staff yourself. These should stay with the desk:

• Hours, location, parking, and the questions you answer twenty times a week.
• Booking, rescheduling and cancelling appointments inside the hours you set.
• Saying no to things you never do, when you have told it what those are.
• Taking a message for a routine callback that is not urgent.

If your transcripts show the desk handing off routine calls, that is usually a knowledge gap. Give it the answer and it stops.

How to check it before a customer does

During rehearsal, run the five triggers on purpose:

1. Ask for the owner. Your handoff phone should ring.
2. Let it ring out. You should get the name-and-number alert.
3. Sound annoyed and repeat a question. Listen for the offer of a person.
4. Ask something outside the trade's lane. Listen for the refusal and the offer.
5. Ask something you never told it. Listen for the honest "I don't have that", not a guess.

Ten minutes. Then you know where the edge is, and so does your desk.

Why we treat this as the product, not a fallback

A receptionist that can do everything is a receptionist that will eventually say something you would never have said. The one that knows when to stop is the one you can leave alone at 7 p.m. Handoff is not the failure case. It is the reason the rest of the job can be trusted.
