AI voice agent for customer service: every call of the day, who handled it and how it ended, real Zanus AI screen

Today's calls

Each row of the day shows who called, whether the AI or a colleague handled it, how long it took and how the call ended.

Easy setupSet up everything just by talking to Lisa AISee how ›

You“Billing disputes go to a person; order and status calls stay with the AI.”

Lisa“Billing becomes people first for disputes, and Orders stays AI only. Here is the before and after. Apply?”

You talk. Lisa sets it up. Applied only on your yes.

How Customer Service use it

A carrier delay sends a wave of where-is-my-order calls; each caller hears the parcel's status and receives the tracking link by e-mail.

A caller whose dishwasher shows an error code is walked through the first checks from your manual before a technician ticket is filed.

A customer disputing a charge is put through to billing, and the colleague hears who is calling and why before the line opens.

REAL AI - the whole Front Office is AI, not old software with an AI button.

What’s included

Keep your number: forward your existing line to your Front Office line and the AI answers immediately, no porting needed. Port the number in when you decide; we handle it with the carrier
A local number in your area, or your own number ported in
Answers on the first ring, 24/7, 365; your business hours only decide when people are reachable
Human-like voice: you choose the voice and the persona per function, greeting, sales, support, booking, callbacks
Receptionist style, no phone menu: the caller just talks in any of 40 languages; the AI detects the language on the first sentence and switches the whole call
Departments you define, sales, support, booking, billing, technical…, each with its own policy: AI first, operator first, or AI only; each with its own AI specialist when no human is free
Directory of your operators with per-day working hours, languages, the nicknames callers use, vacations and temp-worker expiry
Transfers announce the caller and the reason; your person accepts before the call is connected; the call is pulled back before a mobile voicemail can swallow it
Language routing: a Spanish-speaking caller reaches your Spanish-speaking operator first
Hold music with spoken updates; when a person is unavailable the AI says the honest line you wrote for that time of day
Takes messages with the callback number read back and confirmed, delivered to that person's own inbox
Books appointments live from your calendar during the call; captures the e-mail letter by letter; saves the lead
Every fact from your approved knowledge, prices only from your catalog; with no source it says so and offers a person
Robocalls and telemarketers get one polite goodbye and stay away from your team
Off hours your way: full AI service, take-a-message only, or voicemail; holidays and special closures with the message you write
Every call transcribed into the customer's record with a summary; call log with transcripts, exportable; the morning briefing reads it for you

What it does on a call

What an AI voice agent for customer service does

First ring, no phone menu

Callers say what they need in their own words. There is no hold queue and no menu tree, so the customer experience starts with an answer instead of a list of options.

Answers from approved knowledge

Return windows, warranty terms, opening hours and how-tos come from the knowledge you approved, searched by meaning. When nothing on file covers a question, the AI tells the caller so and offers to bring in a colleague.

Orders and tracking on the call

With your store connected, the AI finds the order, says where it is, e-mails the tracking and changes a shipping address before dispatch on the same order record.

Tickets opened with the details

When a problem needs follow-up, the AI opens a ticket with the department and priority read from the caller's words, and the transcript lands on it a minute later.

Returns and warranty requests

The returns department takes the order, the product and the reason, sends the troubleshooting first and files the return as pending for your team to approve.

Calls written onto the record

Every call is saved with its transcript, summary and outcome on the customer's record, and new callers become contacts, so the next agent starts from the whole story.

Calls it handles

AI voice agents for customer service at the busiest moments

Six customer service use cases, from the morning the call volume spikes to the quiet evening fault.

The outage morning

A service interruption fills the line. Every caller is answered at once, hears the status message you approved and, when their problem is a different one, has a ticket opened with their details.

The late-evening fault

At 10 PM a customer's heater stops. The AI asks what was tried, e-mails the steps for that model and opens a technician ticket when the fix fails.

The angry repeat caller

A customer calls a third time about a missing refund. The AI quotes the open case, tells him honestly what happens next and rings the billing colleague your rules name.

The caller in another language

A customer describes a damaged delivery in Portuguese. The AI answers in Portuguese from the same knowledge and files the ticket, which your team can read in English.

The visit that needs a technician

A boiler fault needs a visit. With AI Booking added, appointment scheduling happens on the same call: the AI offers only free times for that service and books one before the caller hangs up.

The payment link that went missing

A customer cannot find the link to pay for a repair. With your store connected, the AI finds the order and sends the payment link again while she is still on the line.

How it works

How conversational AI answers a customer service call

Voice AI on a service line is more than a recorded greeting: four things happen in real time while the customer talks.

Speech recognition, no menus

Speech recognition turns the caller's words into text as they speak, so there are no call flows to draw and no list of options for the customer to sit through.

Meaning, not keywords

The AI agent works out what the caller means and searches your approved knowledge by meaning, so 'my parcel never came' and 'where is my delivery' lead to the same answer.

One voice per department

Orders, billing and returns each answer as their own AI voice agent, with a name, voice and pace you choose, so the whole line keeps one brand voice.

Followed while it happens

A manager can follow any call live from the screen while the AI talks, and the transcript and summary follow on the customer's record after the call.

Compare

AI voice agent for customer support versus the usual phone set-ups

What a customer hears from each way a service line is usually answered, from a phone menu to voice automation that holds a conversation.

What you need	A phone menu and hold queue	An outsourced answering service	AI Phone
The first ten seconds	A list of options to sit through	An operator reading a greeting card	A greeting and a question: in the caller's own language
Where is my order	On hold until an agent frees up	A message for your team	The status on the call: and the tracking sent by e-mail
A product fault	Transferred to support	Noted for a callback	Troubleshooting from your manual: then a ticket when the fix fails
A refund outside policy	Depends on who picks up	A message for the morning	Routed to the person you named: who hears the caller and the reason first
After the call	Notes typed by the agent, if any	A message sheet by e-mail	Transcript and summary saved: on the customer's record

One platform

AI agents across every channel, not a voice-only tool

AI Phone is one part of an AI platform: the same departments and the same knowledge answer across voice, chat and email.

Voice chat on your website

With AI Webchat added, a visitor taps her picture on your site and talks; it is voice chat from the same knowledge and the same departments that answer your service line.

The same words in every reply

The AI agents work from one approved knowledge base, so a return window told on a call reads the same in an e-mail reply or a web form answer sent at night.

One record across channels

A customer who calls, then chats, then writes lands on one record in AI CRM, so the next answer starts from everything said across multiple channels.

Your human agents in the loop

A transfer rings your human agents on the computer, the phone app or the mobile, and they hear who is calling and why before the line connects.

Your rules

What the voice agent leaves to your service team

AI voice agents handle the routine calls; these stay with your service team by rule.

Exceptions and goodwill

Refunds outside the window, credits and price exceptions are never granted on the call; the AI routes them, or opens a ticket for the colleague who decides.

Hazards and urgent faults

A reported hazard follows the safety script you approved and rings the on-call colleague, trying the computer, the phone app and the mobile in the order that colleague set.

When nobody is free

Outside staff hours the AI keeps answering, takes a message or opens a ticket, and the morning briefing lists what came in overnight.

Ready in 2 minutes

Name the departments

Orders, billing, technical support and returns each get an AI voice, and each is set to AI only, AI first or your people first.

Questions & answers

AI voice agent for customer service: questions before you switch

What is an AI voice agent for customer service?

It is software that answers your customer service calls by voice, understands what the caller says in their own words and does the job on the call. AI Phone answers from your approved knowledge, finds orders, takes return requests, opens tickets and routes a caller to the right person, then writes the call onto the customer's record.

Can AI voice agents answer customer service calls 24/7?

Yes. AI Phone answers on the first ring at any hour, weekends and holidays included. Your staff hours only decide when a transfer to a person is possible; outside them the AI keeps answering, opens the ticket or takes a message, and on a holiday callers first hear the message you wrote for that day.

How does the voice agent route calls to the right department?

Callers simply say why they are calling, since AI voice agents for customer support need no phone menu. The AI routes by reason and language to orders, billing, technical support, returns or a named colleague, and each department runs AI only, AI first or your people first. Transfers ring the colleague's computer, phone app or mobile in the order that colleague chose.

Can the AI tell a caller where their order is?

Yes, with your store or catalog connected. The AI finds the order, says where it stands, e-mails the tracking with the carrier's page and can change the shipping address before dispatch. An order the carrier marked delivered is reported as delivered, and a caller who lost a payment link has it sent again.

How does a caller reach a person?

By asking for one. When a caller wants a person, or your rules say the reason needs one, the AI rings that colleague and announces the caller before connecting. When nobody can be reached, the caller hears the honest line you prepared for that hour and the AI takes a message, reading the callback number back digit by digit.

Can the voice agent troubleshoot a product before opening a ticket?

Yes. For each department you write the questions the AI must settle and the steps the customer must have tried. The AI asks them on the call, e-mails the troubleshooting steps with your product videos and pages, and opens a ticket only when the fix did not work. A caller with a case already open hears it quoted instead.

Are customer service calls recorded and transcribed?

Every call the AI answers is saved with its transcript, its summary and its outcome on the customer's record. Call recording is a setting you switch on, and the AI can tell callers the call may be recorded. Managers can also follow a live call while it is happening.

Can I keep our customer service phone number?

Yes. Forward the number your customers already call to your Front Office number and the AI answers from that minute, with no porting and no new phone system. If you later want the number moved in, the port is arranged with your carrier, or you can take a new local number.

Which languages does the voice agent speak?

It answers in the caller's language and can route calls by language, so a Spanish-speaking customer and an English-speaking one each get answers in their own words from the same approved knowledge. Each AI department has its own name, voice and pace, set in your phone settings.

How much does an AI voice agent for customer support cost?

AI Phone is priced per company, never per seat or per agent, so the whole service team shares one subscription. The plans are on the pricing page, and the 7-day free trial runs on your own service line with no credit card.

What makes the best AI voice agent for customer service?

The best AI voice agent for a service line answers only from what you approved, admits when it does not know, finishes the job on the call and hands over with the whole story. AI Phone does all four on your own number, and a week of real customer calls lets you judge it.

How is an AI voice agent different from a contact center?

A contact center queues callers for the next free person, often behind a phone menu. AI Phone answers each caller without a hold queue, even when call volume spikes, settles what your knowledge covers and passes only the rest to your human agents, announced before the line connects.
