Answer Every Call in English and Spanish, Even After Hours

The phone rings while you are on a job, with a customer, or asleep. The caller does not leave a voicemail. They call the next business on the list. If they speak Spanish and nobody on shift does, they may not call at all. You never see the loss, because a missed call does not complain.

This is the setup I build for local service businesses and clinic front desks: every call and text answered in English or Spanish, booked into the calendar when it should be, and summarized for the person who has to act on it. It is written for the owner or the office manager, not for a developer.

Where calls get lost today

Before you buy anything, export the last 30 days of calls from your phone system or carrier portal and sort them into four piles:

• Missed during business hours. The line was busy, everyone was with a customer, or it rang out.
• After hours. Evenings, weekends and holidays. Write down the hours the calls bunch up in.
• Language. Short calls, voicemails in Spanish, callers the team could not help. Your front desk remembers these.
• Hang-ups in the phone menu. If callers hear 'press 1 for', check how many quit before they reach anyone.

Then check what happened next. A missed call returned within the hour is a different problem from one nobody returned. Write the counts down; you will compare against them later.

Missed-call text back, AI receptionist or answering service?

There are four building blocks. Most businesses end up running two or three of them together.

Small offices rarely need all four on day one. The usual mix is text back plus an AI receptionist after hours, with a person, on your team or at an answering service, as the backup for anything the AI should not handle. The order I set them up in is under step by step.

What an AI receptionist should do, and never do

An assistant on your phone line is a new hire that never gets tired and has no judgment you did not give it. Write its job down like you would for a new front desk employee.

It should

• Say in the first sentence that it is an AI assistant, and that the call is recorded if it is.
• Offer Spanish once, then stay in the caller's language, and switch if the caller does.
• Get the name, callback number and reason for the call, plus the ZIP code for service visits.
• Answer only from your approved list: hours, location, services, what to bring, and the price ranges you wrote down.
• Book, reschedule or cancel inside the rules you set, then text a confirmation if the caller said yes to texts.
• Hand off or take a message when the caller asks for a person, is upset, or asks something off the list.
• Tell anyone describing an emergency to hang up and call 911, then alert you right away.

It never

• Pretends to be a person, or dodges the question when a caller asks.
• Quotes a price, a discount or an arrival time that is not on the approved list.
• Gives medical, legal or insurance advice, or says whether a visit will be covered.
• Confirms to anyone that a person is your client. At a clinic, that question goes to staff.
• Takes card or ID numbers by voice. If a deposit is needed, it texts a payment link from your billing system.
• Makes sales calls or sends sales texts to people who did not ask to hear from you.

A bilingual greeting and booking script (English and Spanish)

Write the Spanish yourself or have a bilingual person on your team write it. Do not run the English through a translator: a Spanish speaker hears stiff, word-for-word Spanish in the first sentence and hangs up the way anyone hangs up on a bad phone menu.

Use usted unless your brand is casual on purpose, keep sentences short, and read both versions out loud. Start from these drafts and replace the brackets.

Thanks for calling [Business name]. I'm the office's AI assistant, and this call is recorded so we can follow up. Para español, diga 'español'.

I can book, change or cancel an appointment, or take a message for the team. What can I help you with?

[Booking]
Sure. Can I get your first and last name?
What is the appointment for?
[Service visits] What is the address or ZIP code for the visit?
I have [day] at [time] or [day] at [time]. Which works better?
You're set for [service] on [day] at [time]. Is it OK to text your confirmation to this number?
[If yes] It's on its way. You can reply STOP anytime to stop texts.
Is there anything the team should know before the visit?

[Outside its list]
That one is for the team. I'll send them your message now, and someone will call you back [when, from your rules]. Is this the best number to reach you?

Gracias por llamar a [Nombre del negocio]. Le atiende el asistente virtual de la oficina, un sistema de inteligencia artificial. Esta llamada se graba para poder darle seguimiento. For English, say 'English'.

Puedo hacer, cambiar o cancelar una cita, o tomar un mensaje para el equipo. ¿En qué le puedo ayudar?

[Para hacer una cita]
Con gusto. ¿Me da su nombre y apellido, por favor?
¿Para qué servicio es la cita?
[Visitas a domicilio] ¿Cuál es la dirección o el código postal?
Tengo disponible el [día] a las [hora] o el [día] a las [hora]. ¿Cuál le queda mejor?
Listo. Su cita para [servicio] queda el [día] a las [hora]. ¿Le puedo enviar la confirmación por mensaje de texto a este número?
[Si dice que sí] Ya se la envío. Si en algún momento no quiere recibir mensajes, responda STOP.
¿Hay algo que el equipo deba saber antes de la cita?

[Fuera de su lista]
Esa pregunta la tiene que contestar alguien del equipo. Les envío su mensaje ahora y alguien le devolverá la llamada [cuándo, según sus reglas]. ¿Este es el mejor número para comunicarnos con usted?

To turn your own answers into the assistant's instructions, fill in this prompt and paste it into Claude or ChatGPT. You get a first draft to edit, not a finished script.

Write the instructions for an AI phone assistant at my business. It answers calls in English and Spanish when my team cannot.

Business, services, hours, service area by ZIP code: [fill in]
Appointment types and lengths: [list]
Where most of my Spanish-speaking callers are from: [answer]
Top caller questions, with my answers: [paste]
Prices it may share: [list, or 'none']
Calls that must go to a person, and what counts as an emergency: [list]

Write: 1) a greeting that says it is an AI and the call is recorded, in English and in natural everyday Spanish using usted; 2) the booking steps; 3) what it must never say or promise; 4) handoff and message lines in both languages. Short sentences. Then flag anything in my answers that is vague or sounds like a promise.

Book appointments straight into your calendar

Booking is where an assistant does the most good, and where loose rules do the most damage. Connect it to the calendar in your scheduling or practice software and give it rules, not judgment:

• Appointment types, with the length and the buffer after each one, drive time included for service calls.
• Whose calendar it books on, and which slots stay off limits, such as time held for same-day work.
• Service area by ZIP code, so it never books a visit you will not drive to.
• Book or request. Start with requests: the assistant holds the slot and a person confirms it in the morning. Switch to direct booking once a few weeks of requests look right.
• Confirmation and reminder texts in the caller's language, sent only to callers who said yes to texts.

If your software will not let an outside tool write appointments, the fallback is a request in your inbox and a text telling the caller the team will confirm. That still beats a missed call.

The call summary the owner gets

The summary is what turns an answered call into work that gets done. You should be able to read it in ten seconds and know whether to act. This is the template I give every assistant:

Caller: [name], [number]
Language: [English or Spanish]
Customer: [new / existing / not sure]
Reason: [one line, in English even if the call was in Spanish]
Urgency: [emergency / today / this week / no rush]
What the assistant did: [booked / requested a slot / took a message / handed off]
Promised to the caller: [exactly what was said about callbacks, times or prices]
Texts: [consent given yes or no, and what was sent]
Next step: [one action, who owns it, and by when]
Recording and transcript: [link]

Send each summary to whoever acts on it, and send the owner one short morning list of everything that came in overnight. The line I care most about is Promised to the caller: if the assistant promised a callback, someone on your team owns it.

U.S. business texting rules: 10DLC, opt-in, opt-out, quiet hours

Texts only help if they arrive and you are allowed to send them. Set this up before the first message goes out. The federal opt-out rules were rewritten in 2024 and again in September 2026, so confirm the current version with your texting provider.

Register the number

Business texts from a regular 10-digit number run on what carriers call A2P 10DLC, and carriers filter or block business texts from unregistered numbers. Your phone or texting provider registers your business as a brand, and each kind of message as a campaign, with The Campaign Registry. Have your legal business name and tax ID exactly as they appear on your tax filings, and describe each campaign (missed-call replies, appointment confirmations) in plain words with a sample message. Reviews can take a few weeks, so start this first. Toll-free numbers go through their own verification.

Get permission, and keep the record

Text people who asked to hear from you, about what they asked for. On the phone, the assistant asks before it texts, and the answer goes into the call record. A missed-call text is one message about the call they just made: name your business, say how to stop, and describe that exact flow in your campaign registration. Promotions need their own written opt-in, so these numbers never go onto a marketing list.

Honor opt-outs right away

Under federal rules, a reply of STOP, QUIT, END, REVOKE, OPT OUT, CANCEL or UNSUBSCRIBE is an opt-out, and plain requests like 'stop texting me' can count too. Spanish speakers may write ALTO, BASTA or 'ya no me manden mensajes', so set your system to handle those exactly like STOP. The outer limit to process an opt-out is ten business days, and a shorter one has been proposed; set yours to stop on the spot. One short confirmation, with no marketing in it, is allowed.

Respect quiet hours

Federal rules bar sales calls and texts before 8 a.m. or after 9 p.m., local time where the person is, and some states set narrower windows. A reply to someone who just texted you is a different case, but I still hold automated follow-ups until morning.

Telling callers they are talking to an AI

Say it in the first sentence of every call. Some states already require a business to disclose an AI in certain conversations, more are writing rules, and a caller who finds out on their own feels tricked. When a caller asks whether they are talking to a real person, the answer is a plain no, then an offer to take a message or transfer.

Three related rules to settle with the vendor before launch:

• Recording. Recording laws differ by state, and some require consent from everyone on the call. The greeting says the call is recorded.
• Outbound calls. Federal regulators have ruled that an AI-generated voice counts as an artificial voice under the robocall law (the TCPA), so in most cases calls the assistant places need the person's prior consent. I keep the assistant on incoming calls; follow-ups are texts the caller agreed to, or calls from a person.
• Clinics. If your practice is covered by HIPAA, an AI phone vendor that handles caller information on your behalf is a business associate. Get a signed business associate agreement before the first live call, and skip any vendor that will not sign one.

How to set it up, step by step

1. 01

   Count the gaps

   Sort 30 days of calls into missed, after hours, Spanish and menu hang-ups. Save the counts.

2. 02

   Start texting registration

   Have your phone provider register your brand and campaigns. It is the slowest step.

3. 03

   Write the answers

   List the top caller questions with your answers, the prices it may share, and the calls that go to a person.

4. 04

   Write both scripts

   Draft the greeting and booking script in both languages; a native Spanish speaker reads it aloud and fixes it.

5. 05

   Connect the calendar in request mode

   Let the assistant hold slots for a person to confirm until the bookings look right.

6. 06

   Set the handoffs

   Decide who gets emergencies, who gets messages, and who takes the calls the assistant should not.

7. 07

   Go live after hours first

   Run it nights and weekends for two weeks, read every summary, and listen to calls in both languages. Then add daytime overflow.

8. 08

   Review every week

   Fix lines where callers got stuck, add answers to new questions, and compare missed calls to your starting count.

Test it with real call scenarios

Before a customer hears it, call it yourself and have two or three people on your team call it, including a native Spanish speaker. Use the calls you really get, not polite ones, and for each test check the transcript, the calendar entry, the text sent and the summary.

Measure it: missed calls before and after

You do not need a dashboard. Take the same counts again four weeks after launch, over a similar stretch of the calendar so a holiday or a slow season does not fool you.

• Missed calls that got no answer, no text and no callback by the next business day.
• After-hours calls, and how many became a booking, a request or a message.
• Spanish calls, and how many ended with something done.
• Handoffs and complaints: calls the assistant passed to a person, and any caller who was unhappy with it.

Then listen to a handful of recordings each week, in both languages, with the summaries next to them. The counts tell you whether it is working. The recordings tell you why.

What I would build first

For most owners I'd start with three pieces: register the number and turn on missed-call text back in both languages, put an AI receptionist on nights and weekends in request mode, and send one morning summary of everything that came in. Daytime overflow and direct booking come after a few weeks of clean summaries. If leads also reach you by web form or email, the follow-up guide covers that side.
