What it handles
A receptionist that never sleeps
Answers your FAQs
Hours, pricing, location, services, directions. In your words, the way you would say it.
Routes the urgent ones
A real emergency rings straight through to you. You decide what counts as urgent.
Qualifies the caller
Asks the right questions, captures the details, and drops a clean lead into your CRM with notes.
Covers after-hours and overflow
When you are closed, on a job, or every line is busy, the agent is still answering.
Follows up by text
Sends a confirmation, a reminder, or a booking link so nothing slips between the call and the visit.
For restaurants
Every call during the rush is an order on the line
The phone rings hardest at six o'clock, the exact moment nobody can grab it. Those are takeout orders, tables for tonight, and catering jobs going to the place down the street that did pick up. Your agent answers every one, in your voice, while the kitchen keeps moving.
Takes the order, start to finish
Reads your menu, takes the takeout or delivery order, repeats it back, and fires it straight to your POS or kitchen (Toast, Square, Clover), with a pay link if you want payment up front.
Books and manages tables
Party size, time, the high chair, the window booth. Reservations land in your system without anyone leaving the floor.
Owns the dinner rush
Six to eight on a Friday, every line lit, every hand full. The agent answers all of them at once so no order rolls to voicemail.
Catches catering and big parties
The high-ticket calls get qualified, captured, and routed to you, instead of getting lost in the weeds of a busy shift.
Answers what everyone asks
Hours, the menu, gluten-free options, parking, "are you open on the Fourth." Answered instantly, in your words.
Upsells like a good server
Adds the drink, the dessert, the family meal deal, naturally, on every order. It pays for itself before the night is over.
Do the rush-hour math
15missed calls a week
$32average takeout ticket
$1,900+walking out the door a month
That is one slow week. Every unanswered call during the rush is an order, a table, or a catering job you already paid to ring the phone. The agent puts that revenue back on the line.

Common Questions
Does it actually sound human?
+
Yes. Natural voice, natural pacing, and your script. Most callers cannot tell, and the ones who can do not mind, because they got a real answer instead of voicemail.
What happens with a call it cannot handle?
+
It does not guess. It captures the details, books a callback, or routes a true emergency straight to you. You set the rules for what it handles and what it escalates.
How fast can it go live?
+
Most voice agents are live on your number in about a week, from first conversation to answering real calls.
Does it work with my calendar and CRM?
+
Yes. It books against your real availability and writes every call into your CRM, whether that is Zoho, HubSpot, Acuity, or a custom build.
What does it cost?
+
Quoted after a short discovery call and scoped to your call volume. It usually costs less than a part-time receptionist and never misses a call.
Will it really cover nights and weekends?
+
That is the entire point. It answers every call, every hour, including the after-hours calls quietly going to voicemail right now.
Can the voice agent speak other languages?
+
Yes. It speaks over 100 languages and detects the caller automatically, then answers in their language. English, Spanish, French, Portuguese, German, Mandarin, and dozens more. Pick a language on the live demo above and talk to it yourself.
Will it switch languages if my customer does?
+
Yes. It detects the language the caller is speaking and responds in kind, and it can switch mid-conversation. That means you serve Spanish-speaking and multilingual customers without a second phone line or a bilingual receptionist.
Can it take restaurant orders and send them to my kitchen?
+
Yes. It reads your menu, takes the full takeout or delivery order, repeats it back to the caller, and sends it to your kitchen or POS, with a pay link or card capture if you want payment up front.
Can it handle the dinner rush when every call comes at once?
+
That is when it earns its keep. It answers every line at the same time, so the Friday-night flood of takeout and reservation calls all get handled instead of rolling to voicemail.
