How to set up an AI phone receptionist (in about 10 minutes)

By Prime Circa · June 20, 2026

If your phone rings while you're on a job, with a customer, or asleep, that call usually goes to voicemail and the caller hangs up. An AI phone receptionist answers instead. Here's how one actually works, and how to set yours up in about ten minutes by talking to her once.


How it works

Start with the call itself. A customer dials your normal business number, the same one on your truck, your website, and your Google listing. Nothing changes for them. What changes is where the call goes when you can't pick up.

You have two ways to route calls to Vanessa. You can forward your existing line to her, and you can set that to happen only when you're busy or don't answer, so you still take every call you can. Or you can give her a dedicated number of her own and send calls there. Either way, she picks up in about one ring.

When she answers, she sounds like a person, not a phone tree. She replies in under a second, so there's no awkward dead air. She talks from what she knows about your business: what you do, your hours, your prices, your service area. If a caller wants to book and you've set that up, she books the appointment. If they just need to leave a message, she takes it. And if the call is urgent or needs you specifically, she hands it off or routes it to you live.

After every call, she notifies you, so you see who called, what they wanted, and what she did about it. She reads SMS and email too, so a customer who texts your number still gets an answer.

That instant pickup is the whole game. A Harvard Business Review study by MIT's Dr. James Oldroyd found answering within five minutes makes you 100× more likely to reach a lead than waiting thirty — which is why operators like Tommy Mello, whose A1 Garage Door Service books a reported 89% of inquiries, drill one rule above all others: answer the phone.

Setting it up, step by step

The whole thing is mostly one conversation. You talk to Vanessa about your business the way you'd brief a new hire, and she builds her knowledge from that.

  1. Tell Vanessa about your business. Talk to her once, for about ten minutes. Cover what you do, your hours and prices, what you never want said, and when you want to be reached live. This is the part that matters most, so be specific.
  2. Choose how calls reach her. Pick a dedicated number for her, or forward your existing line. If you forward, you can send her only your missed and after-hours calls so you keep answering when you're free.
  3. Set your handoff and booking rules. Tell her which calls to pass straight to you, and, if you take appointments, when and how she should book them.
  4. Make a test call. Call your own number the way a customer would. Listen to how she answers, ask a couple of normal questions, and check that she gets the details right.
  5. Go live. Once the test call sounds right, turn it on. From here she's answering real customers, and you can correct anything she gets wrong as you go.

You manage all of this from the app, which is on Android today, with iOS coming later.


Call forwarding, briefly

Forwarding sounds technical, but it's a standard feature on nearly every business phone and carrier. The useful part is conditional forwarding: instead of sending every call away, you forward a call only when your line is busy or when you don't answer after a few rings.

That means you stay in control. When you're free, you answer like always. When you're on another call or away from the phone, the call rolls to Vanessa instead of to voicemail. Your carrier usually has a short code or a setting in their app to switch this on, and the setup walks you through it for the major carriers.


What to tell her

The ten-minute conversation works best if you come ready with three things. Get these right and the rest takes care of itself.

1. Your services, prices, and hours

This is what callers ask about most. Tell her what you offer, roughly what it costs, when you're open, and where you work. The more concrete you are, the fewer times she has to say she'll check and get back to them.

2. What she should never say

Just as important as what to say is what to avoid. Maybe you don't quote firm prices over the phone, don't promise same-day service, or don't take certain jobs. Spell out your hard lines so she stays inside them.

3. When to grab you live

Decide which calls are worth interrupting you for — an emergency, a big quote, a specific person — and tell her to route those straight to you. Everything else she can handle or take a message for, so your phone only rings when it should.


After you go live: check her work

Here's the honest part. This is not set-and-forget on day one. Vanessa is good out of the gate, but she learns your business the way a new receptionist would, and the first week is where you tune her.

Plan to listen to a few real calls in the first few days. You'll catch small things — a price she quoted a little off, a question she handled stiffly, a call she should have passed to you and didn't. When you find one, you correct her, and she takes the correction. A little attention up front pays off, because every fix means fewer surprises later.

If you're still deciding whether it's worth it, it helps to know what missed calls cost. For most small businesses, a handful of caught calls a month more than covers it.

One note on scope: Vanessa answers calls for most small businesses, but she does not do medical, legal, or dental triage. If that's your work, she isn't the right fit for the phones.


What it costs

Vanessa is $49 a month, which includes 120 minutes, about 60 calls. Minutes past that are $0.49 each. The first 100 businesses to sign up lock in $29 a month for life. You can pause or cancel anytime, so there's no long commitment while you try it.
