Ranked #1
on EVA-Bench and Speech Agent Arena
Answer every call to your main number, open or closed
Callers get an answer, the right desk or a saved voicemail, and the agent follows your hours and rules.
The agent answers questions on hours, key cutting, delivery windows and returns from your sheet, and holiday hours from your calendar.
The agent checks your inventory for the item and tells callers what the store has on the shelf.
After close, the agent takes a voicemail, reads the callback number back and saves it with a transcript to your inbox.
When you mark a snow day or holiday on your hours calendar, the agent tells the next caller and offers a voicemail.
Automated phone system basics, and where a voice agent fits
What is an automated phone system?
An automated phone system answers your main number without a person picking up. Older setups, often called an automated attendant or IVR, play a keypad menu. Newer ones use a voice agent that talks with callers, and that's what this is.
- Check store hours
- Check item in stock
- Save voicemail
- Transfer to pro desk
Why can't a phone menu tell me what's in stock?
"Press 3 for hardware" tells nobody what's on the shelf. Juniper Hardware's phone asks the same things all day, and staff answer from the register while a customer waits. The agent checks your inventory through a tool and reports what it returns.
Do you have 3-inch deck screws?
check_item_in_stock350-ct box: in stock, Main St
The system shows boxes of 350 in stock at Main Street.
What happens to a call after closing?
Mac transfers contractor accounts to the pro desk only while it's open. After close it takes a voicemail, reads the number back and saves it with a transcript. Mark a snow day on your hours calendar and the next caller hears about it.
- Sunday hours and key cutting0:36
- Deck screws in stock0:52
- Contractor account, to pro desk1:09
Do I need a new PBX for an automated phone system for business?
No. The agent sits in front of what you have, so phones, extensions and staff stay put, and you forward your number or connect your provider. An automated phone system for doctors offices handles different calls, so start from the medical answering service page instead.
Call ended with a next step
Did the call end with an answer, a completed transfer, or a saved voicemail with a callback number?
Fewer interruptions at the counter
An automated phone answering system for small business earns its keep on boring calls. Here's what comes off your staff's plate, and what stays on it.
Routine questions stop at the agent
Sunday hours, the price of a duplicate key and your returns policy all get answered from your sheet, without anyone leaving a customer.
Stock checks without a walk down the aisle
The agent asks your inventory and reports what it returns, like boxes of 350 in stock at Main Street. Callers show up knowing it's there.
Transfers only reach open desks
Today's hours get read before each transfer, so a contractor at 6 p.m. gets a voicemail for the pro desk and not ten rings of nothing.
Snow days change in one place
Update your hours calendar and the agent tells the next caller you're closed and when you reopen. No re-recording the greeting from home.
Voicemail arrives as text
Messages reach your inbox with a transcript and a callback number that was read back, so a mumbled number doesn't cost you the order.
Your phones and your people stay put
This won't rewire your office or take special orders. Hardware and extensions stay, and anything needing an account goes to a person.
A main line that talks like the shop it answers for
A business automated phone answering system has one job on most calls. Callers want a quick fact, and Cartesia's speech models let them ask in one breath and get off the phone.
- $0.03per minute
- #1on Speech Agent Arena and EVA-Bench
- 24/7answers every call, at any hour
Gets "3-inch deck screws" the first time
People rattle off sizes and half-remembered product names, then change their mind. The agent lets them finish and asks one question if it needs to.
Sheet, stock and hours in one call
Choose the LLM, then give it the tools that check store hours, check an item in stock, save a voicemail and transfer to the pro desk.
Friendly enough for the regulars
Someone at your counter is the benchmark. Try voice library options until the main line stops feeling like a machine in a closet.
Voice agent or keypad menu on your main line
Automated phone system software usually comes down to these choices. Staff picking up in person remains the fair baseline, and the one customers like most.
| Cartesia agent | Press-1 phone menu | Staff at the counter | |
|---|---|---|---|
| How callers ask | In their own words | Listen to options, press a key | In their own words |
| "Do you have this in stock?" | Checks your inventory on the call | No, it routes the call | Yes, after a walk to the aisle |
| Closures and holidays | Read from your hours calendar | Usually a new recording | Whoever is in tells callers |
| An odd or complicated request | Transfers it or takes a voicemail | Caller hunts for a menu option | Yes, people handle this best |
| Rush hour at the store | Calls run at the same time | Menu answers, then callers queue | Phone rings while customers wait |
| Setup | Write a sheet, connect your tools | Usually record prompts and build the tree | Training for each hire |
| How you pay | Per call minute, plus LLM usage and telephony | Usually bundled with a phone plan | Wages, and time off the floor |

Phone system FAQs
What is an automated phone system?
An automated phone answering system that puts a voice agent on your main number. It talks with callers, checks your systems, takes voicemail and transfers calls to the lines you set.
Is there an automated phone system for small business?
Yes. The sample agent answers for a single hardware store: hours, key cutting, delivery windows and returns from your sheet, stock from your inventory, and voicemail after close. For a business that also books visits, see AI receptionist for small business.
Is it the same as an automated attendant phone system?
It does the same job with a voice agent in place of a keypad menu. Callers say what they need, and the agent answers, checks your systems or transfers them to the right line. The AI auto attendant page covers routing callers by name or department.
Can I keep my current phone number with an automated phone system?
Yes. Forward the number to the agent's number, or connect your own phone provider directly.
What does an automated phone system do when nobody can answer?
The agent takes a voicemail, reads the callback number back and saves it to an inbox you connect.
Does an automated phone system replace my phone hardware or my staff?
No. It answers the main number and transfers calls to the lines you set. Your phone hardware, extensions and staff stay in place.
Can the agent transfer a caller to a person?
Yes. A webhook reads today's hours before the agent transfers, so a caller never rings an empty desk. After close, the agent takes a voicemail instead.
How do I set up an automated phone system?
Start by listing what people call about. Clone the sample agent, paste your hours and answers into its sheet, and connect the tools it needs, such as stock and voicemail. Set your transfer lines, then forward your main number or connect your own phone provider. Test it as a customer would before real callers reach it.
What do you call the automated phone system?
The usual names are auto attendant, automated attendant and IVR, which stands for interactive voice response. An auto attendant routes callers, while an IVR can also read information back. This one is a voice agent that does both by conversation. See the AI IVR page for how it replaces a keypad menu.
Is there an automated phone system for a doctor's office?
Yes, though it needs a different setup than a store. The medical office answering service page shows the agent set up for a practice. It sends refill requests to staff, books care team callbacks and reads your 911 script for urgent symptoms. It doesn't give medical advice.
How much does an automated phone system cost?
There's no hardware to buy for the agent. You pay $0.03 per minute of call time, so a store full of quick hours questions runs on short calls. LLM usage is billed separately. A Cartesia phone number adds $0.014 per minute, or nothing if you bring your own Twilio account or SIP trunk. The free plan includes $1 of agent calls a month, so you can test the main line before you pay. See pricing.
