AI voice agent in Australia: how to compare providers

If you have started looking at AI voice agents for your business phone, you will have noticed that every demo sounds impressive. The voice is warm, the answers are quick, and the booking lands in a calendar. That is the point of a demo. The differences between providers show up later: on a bad line, with an awkward caller, when you change your prices, and when the invoice arrives.

This guide is a way to compare providers on the things that matter once the agent is answering your real customers. It does not rank anyone. It gives you the questions to ask, the tests to run and the points to get in writing, so you can compare like with like.

If you want the basics first, read what an AI voice agent can do for a small business phone.

Start with your calls, not the provider

Before you speak to anyone, spend a week noting what actually happens on your phone. It makes every conversation with a provider sharper.

• When do calls come in? During jobs, after hours, at lunch, on weekends?
• What do people ask? Write down the ten most common questions in the caller's own words.
• What should happen at the end of a call? A booking, a quote visit, a message to you, a transfer?
• What must never happen? A price you do not offer, a promise about timing, advice you would not give over the phone.

With that list, you can judge a provider against your business instead of against their script. A provider who does not ask you for this kind of information early is likely to build a generic agent.

Test it like a difficult customer

A demo call made by the salesperson tells you little. Ask for an agent set up with your own information, or at least a trial number, and ring it yourself. Run these tests:

1. Your ten real questions. Ask them the way customers ask them, including the vague ones ("how much is it, roughly?").
2. Something it should not answer. It should say it does not know and offer to pass the message on, not improvise.
3. Pressure on price. Ask for a discount or a time you do not offer, and check it does not agree.
4. Interruptions. Cut in halfway through a sentence. A good agent stops and listens.
5. Noise. Call from a car, a café or a windy street.
6. Names, numbers and suburbs. Spell a surname, read out a mobile number, name a suburb with an unusual spelling. Check what was captured.
7. "Can I speak to a person?" See what happens next and how long it takes.
8. The alert. After each test call, check what you received: who rang, what they wanted, their number, and whether anything is missing.

Do the same tests with every provider you are considering. The results are the comparison.

Questions about handover

Handover is where most of the value, and most of the frustration, sits. Ask each provider:

• What triggers a handover? Upset callers, complaints, questions outside what you approved, a request for a person.
• What does handover look like? A live transfer to your mobile, a callback with notes, or both? Can you choose by time of day?
• What does the caller hear while they wait, and what if you do not pick up?
• Does the context travel with the call? Nobody should have to repeat themselves.

Questions about data and privacy

A voice agent hears names, phone numbers, addresses and sometimes health or financial details. The Office of the Australian Information Commissioner (OAIC) has published guidance on privacy and the use of commercially available AI products for organisations covered by the Privacy Act. It recommends due diligence before adopting a product, and updating privacy policies with clear information about how AI is used. Questions it prompts, in plain terms:

• Where are recordings and transcripts stored, and for how long? Can you ask for them to be deleted?
• Who can access them? Does the provider or any third party get access to what your callers say, and is it used to train anything?
• How is personal information protected? Ask what security measures are in place.
• Is the call recorded? If so, how are callers told? Rules on recording calls differ between states and territories.

Not every small business is covered by the Privacy Act in the same way, and this is general information, not legal advice. Consult your adviser about what applies to your business.

Questions about setup and changes

• Who writes the script, and do you approve it before go-live? You should hear the voice and read the answers before a customer does.
• How do changes work? Prices, hours and services change. Ask how you request an update, who makes it and whether it costs extra.
• Can you keep your number? Most setups answer calls forwarded from your existing number. Ask who handles the forwarding and what your phone provider charges for it.
• What does it connect to? Calendar, booking or job software. Ask which integrations are included and which are quoted separately.
• What happens if it goes down? Ask where calls go if the service has a problem.

Questions about cost

Prices are hard to compare because providers package them differently. Ask each one for the same four numbers, in writing:

1. Setup: what it covers (voice, script, testing, forwarding, integrations).
2. Monthly fee: what is included, and whether there is a minimum term.
3. Minutes: how many are included, and what happens when you go over.
4. Extras: phone number and carrier costs, integrations, changes to the script.

Then work out what a normal month and a busy month would cost you. A low monthly fee with a small minute allowance can end up dearer than a higher fee with more minutes included. Also compare against your alternatives, such as an answering service or another hire; we wrote up how an AI receptionist compares with an answering service or hiring.

Red flags

• No trial with your own information before you sign.
• No clear answer on data: where it is stored, who sees it, how long it is kept.
• Lock-in you did not expect: long contracts, or a number you cannot take back.
• Promises of results, such as a set number of extra bookings. Nobody can know that before your calls are answered.
• Script changes that need a ticket and a week. Your business changes faster than that.

Maybe you need less than a voice agent

If your main problem is missed calls while you are busy, a simpler step can be enough: missed-call text back sends a text to anyone you could not answer, so the lead does not go cold. If your customers mostly message rather than ring, a chat assistant may fit better. A voice agent earns its place when calls are frequent, repetitive and come in when you cannot pick up.

What it costs with Realtiq

The setup includes agreeing the voice and script with you, and you approve it before it goes live. Two hundred minutes of calls a month are included, and the proposal sets out how calls beyond that are handled. It runs month to month. Integrations are scoped and quoted separately. You can ring 0495 052 154 to hear Realtiq's own voice agent and run some of the tests above on it, or see the voice agent page.

Common questions

How long should I trial a voice agent before deciding?

Long enough to run the tests in this guide with your own information. A few days of real calls with you watching the alerts tells you more than a polished demo.

Should I compare overseas providers too?

You can. Ask the same questions about data, storage location, support hours and how they handle Australian numbers and accents, and compare in Australian dollars.

Can a voice agent take payments over the phone?

Some can, through a payment integration. Treat it as a separate question with its own security checks, and ask your adviser about your obligations.

Do I need to tell callers they are talking to an AI?

The OAIC guidance says public-facing AI tools should be clearly identified to users. Ask each provider how their agent introduces itself, and check with your adviser.
