What Is IVR? How a Phone Menu Works, and What Replaces It

A customer rings your store and hears: press 1 for orders, press 2 for everything else. Both options ring the same phone: yours.

That menu is an IVR. You may be looking up what IVR is because the phone has started eating into your day. The real question is who should take the call.

I’m Stefano Bertoli, founder of RuleInside, and I build AI voice agents for WordPress stores. So I sell one alternative to a menu, and I say where a menu is the better choice.

For this guide I read the pages that rank highest in the US for what is ivr. I priced four phone systems and read what store owners say about menus.

I also tested our own demo store’s agent on the calls a menu routes.

IVR stands for interactive voice response. It is the automated system that answers a business call and offers the caller options. TechTarget, a technology publisher, describes a system that “interacts with callers, gathers information and routes calls to the appropriate recipients”.^[1]

USAGov, the US government’s information service, puts it in one line. An IVR “routes callers on a phone tree, based on their voice responses or pressing a specific button”.^[2]

You will also hear it called a phone menu, a phone tree or an auto attendant. Most people use the names loosely. The section on auto attendants below shows where they differ.

Search for ivr and Google’s suggestions add other meanings: a heart rhythm, a stock ticker and a measure used in options trading. One of the pages that rank for what is ivr is a stock page for the ticker IVR. This guide means the phone system only.

The pages that explain IVR are written for contact centres. I read the 19 pages on IVR among the top 20 US results for what is ivr. All 19 describe calls going on to a department or an agent. Fourteen use healthcare as an example, and 12 use banking or finance.

Eighteen of the 19 come from companies that sell something, and 15 sell phone or contact centre products. The remaining page is GetVoIP, a site that reviews phone systems. None names WooCommerce or another store platform. The five that mention ecommerce list it as one item among many.

An IVR handles a call in up to four steps: a greeting, a choice, sometimes a lookup, then a transfer. Amazon’s documentation for its contact centre software gives the classic menu: “Press 1 for Sales, press 2 for Support.”^[3]

The greeting can be your own recording or a computer voice. Microsoft’s admin guide says prompts “can be created by using text-to-speech (system-generated prompts) or by uploading a recorded audio file”.^[4] The same guide says callers can speak or use the keypad.

The lookup step is where an IVR can do more than route. IBM, which sells contact centre software, covers the case where the lookup fails. Then, it says, “the programmed menu options can assist with call routing”.^[5]

A menu can tell callers your opening hours without any store data. To read an order, someone has to connect the menu to your store. In our comparison of automated phone systems, none of the seven documented a WooCommerce order lookup during a call.

The pages that explain IVR skip this step for stores. Of the 19 I read, 10 list order status as a use, mostly as one item in a list. One links order status to an order management system, but does not name one.

Phone menus rest on touch-tone dialling, which arrived in 1963. The IEEE History Center’s wiki says Touch-Tone service began “in the fall of 1963 in Greensburg and Carnegie, Pennsylvania”.^[6] It cost an extra $1.50 a month at the time.

Each key sends two tones at once: one for its row and one for its column. The wiki says the tones sit “within the frequency range of the human voice”. So they travel down the line during a call. That is what lets a computer hear which key you pressed.

The international standard for those tones, ITU-T Recommendation Q.23, is still in force. It fixes eight frequencies, from 697 to 1,633 hertz.^[7] The star and hash keys came in 1968. AT&T began “adding the * and # keys for just the advanced services for which they are used today”.^[6]

IVR took longer than the keypad. TechTarget says the technology “wasn’t cost-effective for wide commercial deployment until the mid-1980s”, when hard drive storage fell in price.^[1] IBM names Moviefone as one of the best-known IVR services of the 1990s. Callers gave their postcode and heard the nearby cinemas and their films.^[5]

The common way to sort IVR is by how the caller answers. IBM names three kinds, each with its own example.^[5]

The top pages for what is ivr do not agree on the types. Seven of the 19 list them, and their lists run from 3 types to 15. Most of the seven sort by how callers answer. One sorts by where the software runs, on your premises or in the cloud, and another mixes both.

Conversational IVR is the natural language kind, with replies in full sentences. TechTarget says natural language processing “enables IVR to deliver a conversational response to callers”.^[1]

On the pages I read, it is sold as an upgrade to the menu. Eleven of the 19 say callers can state their request in their own words. Unless the system can answer the request, the call then goes on to a department or an agent. The section below on what replaces an IVR covers an agent that answers the request itself.

An auto attendant routes calls, while an IVR can also collect information and complete a task. Telebroad sells business phone systems. It calls an auto attendant “a particular simplified application of IVR technology with the function of a virtual receptionist”.^[8]

Nextiva, which sells phone systems, draws the same line on its blog. There, an IVR “routes calls, collects information, authenticates callers, retrieves data from connected business systems, and completes tasks”.^[9]

Microsoft’s admin guide gives an auto attendant’s job: “to direct a caller to an appropriate person or department”.^[4] Another Nextiva page names its limit: “An auto attendant can’t answer questions or take a message beyond a generic voicemail.”^[10]

Some plans list one feature under both names. RingCentral’s plan comparison table lists “Multi-level auto attendant and IVR”.^[11] Nextiva, by contrast, lists its simple IVR and a dial-by-name auto attendant as separate features.^[12] Only 2 of the 19 pages that rank for what is ivr compare the two terms.

So when a plan says auto attendant or IVR, ask one question. Does the menu only route the call, or can it read your data?

For a small store, an IVR comes as a feature of a business phone plan, priced per user each month. Only one of the 19 pages that rank highest in the US for what is ivr gives a price.

So I read four vendors’ own pricing pages on 26 October 2026, from Europe. The prices are in US dollars, as listed. Each row is the cheapest plan that includes a menu.

Two of the four need a note. Google sells Voice on top of a Workspace plan, and that plan costs extra. Lower on Quo’s pricing page, its comparison table lists Business at $23, not the $27 on its plan cards.

Two other phone systems are left out: Grasshopper, whose pricing page did not load its plans for me, and Dialpad, whose menu feature I did not check.

The one page with a price is from GetVoIP, a site that reviews phone systems. It puts contact centre systems with IVR at “$20.00/user per month to $150.00+/user per month”.^[17] Store owners can pay less. One, a manufacturer selling on Amazon and Shopify, built a two-option menu on a $3-a-month phone service.^[18]

The per-user price matters. A store with three people taking calls pays three times the listed price.

Callers put up with menus, and most would rather reach a person. The newest surveys I found that ask about menus are from 2019. One of them was paid for by a company that sells phone systems.

Clutch is a ratings firm for business services. Vonage sells phone systems, and Opinion Matters ran its survey. In Clutch’s survey, the top frustrations were irrelevant options (69%) and not being able to describe the problem (67%).

An older study, published in 2016, points the same way. Boston University researchers surveyed 1,321 online respondents matched to the US population. On phone menus, the researchers report: “Only 10 percent were satisfied with their experience”.^[21] The authors name its funder as the industry group Interactions.

The newest survey I found asks about AI in customer service, not menus. Gartner surveyed 3,566 customers in February and March 2026. Of them, 87% said a company using generative AI must offer a way to reach a human agent.^[22]

Store owners meet the same problem when they are the caller. Of 12 owners who wrote about calling a company, 8 described trouble reaching a person. Seven of those were calling Shopify. One wrote that Shopify “took away the possibility of speaking to a human on the phone”.^[23]

A menu routes calls, so it helps a store only when there is somewhere to route them. A menu earns its place when different people take different calls. In a store run by one or two people, every option can ring the same phone.

Customers still call online stores. Gorgias, which sells a help desk to online stores, compared the same 10,990 brands in early 2024 and early 2026. Requests that began with a phone call rose 20%.^[24]

I read what store owners on Reddit say about their own phone line. Of the 15 who described it, 6 run a menu or an automated line today.

Three say it keeps robocalls away. One owner’s menu sends each caller to the owner’s phone or a staff member’s, depending on the question. One plays a recorded answer, and one tells callers where their parcel is.

That owner, the manufacturer from the price section, set the menu up to stop spam calls: “The bots give up”.^[25] A recorded answer has limits, though. Another owner recorded a message on the menu saying their stock was live, and “people still come through to ask”.^[26]

The owner whose menu rings different phones by question stresses one detail: “it’s not a robotic voice that answers, but my own”.^[27] GetVoIP agrees a small company may not need much: “a simple solution with greetings, menus and call routing will do”.^[17]

Keep the menu short, put the common reasons first and always offer a person. The clearest rules come from two US public bodies.

New Jersey’s Office of Innovation based its guide on user testing and on advice from contact centre staff across the state. One rule reads: “Limit each menu to 5 options if possible”.^[28] Nine options, it says, can take up to a minute to hear.

It also warns against nested menus. When menus get complicated, callers hunt for the fastest way to a person, “often resorting to spamming zero”. Its advice is to try self-service once: “After a self-serve attempt, direct users to an agent.”

USAGov did the same after more than 430,000 calls in 2019: “We limited the main menu to five topics”.^[2] It put the most popular topics first.

Clutch’s advice is plain: “Businesses should always include an option to speak to a live agent in their phone menu.”^[19]

An AI voice agent replaces the menu with a conversation. The caller says what they want, and the agent answers from your store data. Then it passes the call to a person when needed.

Phone system makers are moving the same way. Microsoft’s Teams Phone Agents “screen calls, answer questions, manage appointments, and route callers without fixed menus”.^[4] Five of the 19 pages I read mention AI voice agents. Only one explains how an agent and an IVR fit together, and it says they work in tandem.

Gartner expected big contact centres to go first. In 2022 it predicted early adoption of conversational AI would be “primarily led by organizations with 2,500 or more agents”.^[29] A small store has no such team, which is why we configure and run our agent for you.

Our guide to what voice AI is explains how an agent hears and answers. Our AI voice agent answers your store’s phone and transfers callers live to your phone or your team. You keep your store’s number.

None of the 19 IVR pages tells a business what callers should hear about automation or recording. Have the agent say in its first sentence that it is an AI, and that the call may be recorded. In 2024 the FCC, the US communications regulator, ruled that AI voices count as artificial voices on outgoing calls.^[30] The ruling covers calls a business makes, not calls it answers. I’m not a lawyer, so check the rules where your customers live.

Our demo agent handled all four questions itself. It answered three, and offered a callback when I asked for a person. I tested our own demo store’s AI agent by text chat on 26 October 2026. Velàri Skincare is a demo shop we built, not a client’s store.

I asked about the four things people ring a store for: an order, stock, returns and a person. A press-1 menu would send each one somewhere. Here is what the agent did instead.

The order took two tries. The agent asks the caller to confirm the details before it looks up an order. In my first chat, my next question arrived before I had confirmed. In the second, I confirmed and it read the order back.

This was a text chat, not a phone call, because the chat widget shows no transcript in voice mode. On a phone call, our agent transfers the caller live to your phone, as our AI voice agent page explains.
