If I were setting up an AI receptionist this week, here's what I'd do

An AI receptionist is software that answers your business phone, talks with the caller in a natural voice, answers from your own information, books on your real calendar and sends you a summary. A phone company like Twilio carries the call, an AI model does the talking, and your calendar and customer records do the rest.

Call (520) 552-1235 and you'll hear ours. It answers for Rincon AI and can book you a 30-minute call.

Here's how it works, ring to booked call:

1. You keep your number.
Calls to your number forward to the receptionist, either for every call or only when you don't pick up. Nobody has to learn a new number.

2. A phone company picks up.
We build on Twilio. A local number costs $1.15 a month and an incoming call costs $0.0085 a minute (Twilio's published US prices, August 2026).

3. The voice is three pieces working together.
Speech becomes text, an AI model decides what to say, and text becomes speech again. Twilio calls the bridge for this Conversation Relay, at $0.07 a minute. Good setups answer in about a second.

4. It answers from your own information.
Your services, hours, service area and the prices you are ok with. If the answer isn't in what you gave it, it says so and offers to have you call back.

5. It books on your real calendar.
Open times come from your calendar, the caller picks one, and the invite goes out. Ours texts back with the next open times when someone sends the word BOOK.

6. Every missed call gets a text back.
If someone hangs up before it answers, a text goes out with a way to book. A missed call is usually a lead that called the next business on the list.

7. Hard calls go to a person.
An upset customer, an emergency, anything it isn't sure about: it transfers the call or takes a message and tells you right away.

8. Everything ends up in your company operating system.
This is the part most receptionist products skip. On RinconOS, a new caller becomes a lead in your sales pipeline, a booked call moves it to the right stage, and the recording, transcript and a short summary land in your inbox. The phone call stops being a sticky note and becomes a record you can act on.

What does an AI receptionist cost?

Two parts: the running cost and the build.

The running cost is mostly per minute. Take 300 calls a month at three minutes each:

• Phone number: $1.15
• Incoming minutes: 900 × $0.0085 = $7.65
• Conversation Relay: 900 × $0.07 = $63.00
• Recording, if you keep them: 900 × $0.0025 = $2.25

That's about $74 a month in Twilio charges, plus the AI model's usage, which depends on the model and how long the conversations run.

The build is where the work is: writing down what it should say, connecting your calendar and your customer records, deciding which calls go to a person, and testing it with real calls.

AI vs a virtual receptionist

A virtual receptionist is a person at an answering service, paid by the minute or the call. A person reads tone better and handles the odd call well. An AI receptionist answers at 2 a.m. and on Sundays, picks up every call at once, books straight onto your calendar and puts every call in your records without anyone retyping it.

Plenty of businesses end up with both: the AI answers first and a person takes what it hands off.

Will AI replace receptionists?

For the repetitive calls, mostly yes: hours, directions, "are you open Saturday", booking and rebooking. For the calls that need judgment, no. When we map a process we sort every step four ways: remove it, automate it, give it to an agent, or keep a person handling it. On the phone, the person keeps the calls that matter.

The calls that trip AI receptionists up

Plan for these before you go live:

1. The emergency after hours. A burst pipe at 11 p.m. should page whoever is on call right then. Booking it for Tuesday loses the customer.
2. The existing customer. "Where's my order" needs your records, so the receptionist has to know who's calling before it answers.
3. The price you don't publish. Decide in advance what it says when someone asks for a quote it can't give.
4. The caller who wants a person right away. Let them have one. Making someone argue with a robot costs you the job.
5. Two calls at once. It can take both, so make sure the calendar can't double-book the same slot.
6. Spam and robocalls. Filter them before they become leads in your pipeline.
7. Spanish, or another language. It can answer in the caller's language, and the summary should come to you in yours.
8. Recording consent. Some states require everyone on the call to agree to a recording. Say it at the start of the call.
9. Texting rules. Text-backs need opt-out handling (STOP and HELP), and replies have to be honored.
10. Card numbers. Keep payment details off the call. Send a secure payment link instead.
11. When it doesn't know. The right answer is "I'll have Joe call you back," with the caller's question in the summary.

If I were starting this week

1. Pull your last month of call logs and count the missed calls.
2. Write down the ten questions callers ask most, with the answers.
3. Pick the calls a person keeps, and who gets them.
4. Connect the calendar first. Booking is key!
5. Run it after hours only for two weeks, read every summary, then widen it.

The tools got pretty amazing this year. The work is in what you teach it and where the calls go afterwards.
