An auto attendant is the recorded voice that answers a business line and offers a menu: “Thanks for calling Riverside Plumbing. For service, press 1. For billing, press 2.” It routes callers to the right person, department or voicemail box without anyone having to pick up first. For some small businesses it’s exactly right. For others it’s a polite way of making customers wait before they reach voicemail.
Here’s how auto attendants work, what they cost, how to write a menu that doesn’t annoy people, and when an auto attendant isn’t the answer. We make Ansdale, an AI receptionist, which is a different tool, and we’ve tried to be fair about where each one fits.
What does an auto attendant do?
- Greets callers with a recorded or text-to-speech message.
- Offers a keypad menu and transfers callers to a person, a group of phones, or a voicemail box.
- Follows business hours, playing a different message after hours and on holidays.
- Sends unanswered calls to voicemail, often emailing the message or a transcript.
What it doesn’t do is have a conversation. It can’t answer “do you service tankless water heaters?” or book an appointment. If nobody picks up at the end of the menu, the caller still lands in voicemail.
How much does an auto attendant cost?
Usually little or nothing extra. Most business VoIP phone systems include one. On Google Voice, for example, the auto attendant comes with the Standard plan at $20 per user a month and the Premier plan, but not the $10 Starter plan (checked on Google’s site in October 2026). Our Google Voice answering service guide goes through those plans in detail. The real cost isn’t the software; it’s the callers who give up partway through the menu.
When does an auto attendant make sense?
- You have several people or departments, and callers really do need different ones.
- Someone is usually available to take the call once it’s routed.
- Lots of callers want the same simple information, like your hours or address, which a menu option can play.
When does it get in the way?
For a one- or two-person business, a menu often just adds steps between the customer and the voicemail they were going to get anyway. “Press 1 for sales, press 2 for service” means nothing when both options ring the same cell phone in a truck. New customers calling around for quotes are the least patient callers you have, and a menu is one more reason for them to try the next number.
How do you write an auto attendant menu that works?
- Keep the greeting short. Business name, then straight into options.
- Offer three options at most. People forget anything beyond that.
- Put the most common reason first. For most service businesses that’s booking or service.
- Always offer a person. “Press 0 to speak to someone” stops callers mashing buttons in frustration.
- Don’t say “please listen carefully as our options have changed” unless they really have.
An example for a small trade business:
“Thanks for calling Riverside Plumbing. If you have a leak or emergency, press 1. To book a visit or get a quote, press 2. For anything else, press 0.”
And for after hours:
“Thanks for calling Riverside Plumbing. We’re closed right now and open at 7:30 tomorrow. For an emergency leak, press 1 to reach our on-call plumber. Otherwise, leave a message after the tone and we’ll call you back first thing.”
Record it in a quiet room, or use a clear text-to-speech voice. Our professional voicemail greeting guide has tips that apply to menus too.
Auto attendant vs receptionist vs AI receptionist
| Auto attendant | Human receptionist | AI receptionist | |
|---|---|---|---|
| Answers questions | No, menu only | Yes | Yes, from what you’ve told it |
| Books appointments | No | Yes | Yes, on most products |
| Handles several calls at once | Routes them, but someone still has to answer | One at a time | Yes |
| Hours | 24/7, but ends in voicemail if nobody answers | Working hours | 24/7 |
| Typical cost | Often included in your phone system | A salary | Roughly $25 to $300 a month for small businesses |
Some businesses use both: an auto attendant for routing, and an AI receptionist on the option that would otherwise go to voicemail. Ansdale, which is ours, answers in your business name, books appointments into your calendar and routes urgent calls to you, from $49 a month. Our guide to what an AI receptionist is explains the difference in more detail, and automated answering service covers the wider options.
Questions people ask
What is an auto attendant?
A recorded menu that answers a business phone line and routes callers by keypad choice to a person, a group of phones or a voicemail box. It can follow business hours but doesn’t hold conversations.
Is an auto attendant the same as an IVR?
They overlap. An auto attendant is a simple routing menu. IVR is a broader term that can include looking up account information or taking payments by keypad or voice.
How many options should an auto attendant menu have?
Three at most, with the most common reason first and an option to reach a person.
Does a small business need an auto attendant?
Only if callers need routing to different people who are usually available. For a one- or two-person business, a menu often just delays the caller before voicemail.
