Why the home phone is where the scam calls land

Most of the scam calls I hear about from customers didn't arrive on a smartphone. They came through the cordless phone on the kitchen bench, usually at a parent's place, usually from a number that looked local, and usually while the person who'd normally screen it was out. Smartphones have had spam labelling and silence-unknown-callers settings for years. The old DECT handset sitting in its cradle has none of that, so it rings, and whoever's home answers it.

The telcos are doing more upstream than they used to. ACMA rules now require carriers to identify, trace and block scam calls before they reach you, and plenty get stopped in the network. What gets through is the stuff that looks legitimate: spoofed local numbers, calls that sit just under the detection thresholds, and the follow-up call from someone who already has a name and an address. The conversations worth having with older parents about scams matter more than any hardware, but hardware can take a lot of the volume off, and volume is what wears people down until they slip once.

The pattern I hear about is nearly always the same. A parent gets five or six of these calls a week and hangs up on every one of them, and then one Tuesday the caller has the bank's name and the last four digits of a card, and the conversation goes further than it should. Cutting the number of calls that ring through is the simplest protection there is, because the scam call that never rings can't work.

How call blocking on a home phone actually works

There are three kinds of blocking on the phones in this guide, and they're not equal. The first is a block list: you add a number once it's called you, and the phone refuses it next time. That's useful for the same telemarketer ringing every afternoon and close to useless against scammers, who rotate and spoof numbers constantly. A block list of 1,000 numbers sounds impressive on a box but it's still reactive, because it only knows about numbers that have already got you once.

The second kind blocks by category: withheld numbers, private numbers, unavailable numbers, or whole country and area codes. That's a much bigger net for very little effort, and blocking international prefixes alone catches a good share of the overseas call centre traffic. The catch is that it relies on Caller ID being switched on at the telco end, which some providers still charge for, and it'll also block the occasional legitimate private-number call from a hospital or a government office.

The third kind is the one I'd actually set up for a vulnerable parent: an allow list, sometimes called a trusted list, where known contacts always ring through and everything else is screened or silenced. The Gigaset in this guide states one on the listing. It flips the problem around, because the scammer now has to be on the list instead of you having to guess which number they'll use next. It's also the setting that annoys people the most for the first week, so set expectations before you turn it on.

NBN phones stop in a blackout, 4G phones don't

This catches people out more than anything else in the category. On most NBN connections the home phone plugs into the modem, not the wall, so when the power goes off the modem goes off and the phone goes dead with it. A cordless DECT base needs mains power too. That's fine for most households with a mobile in every pocket, but it's not fine for someone whose home phone is their main line, and it's exactly the person this guide is written for.

Two of the picks get around it by not using the NBN at all. They're 4G phones that take a SIM card and talk to the mobile network, so they keep working through an NBN outage, and the Opel states a back-up battery on the listing. If the house already has a 4G backup internet setup on a battery that keeps the modem alive, a normal cordless phone gets most of that resilience back. Without one, a SIM-based phone is the simpler answer.

One thing to check before buying any SIM-based phone: since the 3G networks closed in 2024, a mobile phone in Australia needs to make calls over 4G (VoLTE) to work at all, including emergency calls. Both 4G picks here are sold as 4G devices on Amazon AU, and the Gigaset states VoLTE on its listing. Older 3G-era seniors phones still turn up second hand and on marketplace listings, and they won't make a call on today's networks.

Big buttons, loud earpieces and hearing aid modes

Blocking is half the brief. The other half is making the phone easy to use for someone whose eyesight or hearing isn't what it was, and that's where the plainest-looking phones sometimes do best. Large backlit keys, a volume boost on the earpiece and a hearing aid (T-coil) mode are the three features that come up most when families ask me what to buy. Picture buttons, where you put a photo of each person on a one-touch key, are brilliant for anyone who struggles with a keypad.

Hearing aid compatibility on these phones means an inductive coupler in the earpiece that the hearing aid picks up when it's switched to its T setting, which cuts down on the whistling feedback you get holding a speaker against a hearing aid mic. The Oricom, Panasonic, VTech CLS22052 and Gigaset all mention it on their listings in some form. If someone in the house uses hearing aids, check which mode their aids actually support with their audiologist before you choose, because not every aid has a telecoil enabled.

Cordless, corded or SIM-based: picking the right type

A DECT cordless set is the default for most homes and it's what three of these picks are, give or take. You get handsets you can carry around the house, an answering machine in the base, and the call-blocking features are usually best on this type because there's a screen and a menu to manage them. The downsides are the power dependence I mentioned and a rechargeable battery in every handset that'll need replacing every few years.

A corded phone has no handset battery to fail and, on some older copper lines, it'll even keep working in a blackout, although that's rare now on the NBN. The Oricom here is corded and it's the most reliable thing in this guide by a long way for the simple reason that there's very little in it to go wrong. What it doesn't do is block anything, so it's the pick for ease of use, not scam defence.

The SIM-based 4G phones sit in between. They behave like a landline, with a desk phone or cordless-style handset and big buttons, but they run on a mobile plan instead. You'll pay for that plan, prepaid is usually fine, and you'll want decent indoor reception in the room where it lives. If you're not sure, check what bars a mobile on the same network gets in that spot before you order. Battery life is longer than a smartphone's because there's no big screen running apps all day, but it's still a lithium battery that needs charging, so a cradle or dock it lives in is worth more than the spec sheet suggests.

Setting one up so it actually blocks something

Nearly every call-blocking phone I've seen come back from a family member's house was blocking nothing, because nobody turned the feature on. Block features usually ship disabled, and the menus are buried. Do the setup yourself before you hand it over: switch on withheld and private number blocking, add international prefixes if the household never gets overseas calls, and load the first few known nuisance numbers into the list while you're there.

Check Caller ID is active on the line, because every Caller ID based feature in this guide does nothing without it. On many NBN voice services it's included, on some it's an add-on, and a two minute check with the provider saves a lot of confusion. Register the number on the free Do Not Call Register too. It won't stop scammers, but it takes legitimate telemarketers out of the mix so whatever still rings is more likely to be worth a second look.

Last, write the setup down. A one-page note taped inside a kitchen cupboard with how to block the last caller and how to turn off the answering machine saves a lot of grief later. If something about the phone stops working and you can't tell whether it's the handset, the base or the line, bring it into our Erina workshop and I'll tell you which before you spend anything.

What one of these costs to own

The sticker price is the small part of owning a home phone. A cordless or corded phone on the NBN rides on whatever voice service comes with the internet plan, so the running cost is whatever the provider charges for the phone line, if anything, plus Caller ID if that's an extra. A 4G home phone needs its own mobile service, and a basic prepaid plan for a phone that mostly receives calls usually runs from a few dollars to the low tens of dollars a month, depending on the carrier and how long each recharge lasts. Over three years that can easily cost more than the phone did, so price it before you choose the 4G route for convenience alone.

Power is close to nothing. A DECT base and a handset charger draw a few watts between them around the clock, and assuming about 3W continuous, that's roughly 26kWh a year, or about $8.70 at the AU average tariff of roughly 33c/kWh.

The real long-term cost is batteries: handset cells every three to five years, a lithium pack on the Gigaset in roughly the same window, and the occasional plug pack. None of that is expensive, and it's the reason a five-year-old cordless phone that has just died is usually worth a battery before it's worth a replacement. That's the case I'd make to any family about to throw one out.

How I picked these five

Every pick is sold new, sits inside a $74 to $179 band, and is sold by Amazon AU or a named Australian storefront, with no import-version listings. Amazon AU doesn't publish a category rank for home phones through its product data, so where a rank is shown it's the website-wide sales rank, which is a blunt number but it's a real one. Two of the DECT sets carry no published rank at all on the day I checked, and I've said so rather than guessed.

I've left out the plug-in call blocker boxes that sit between the phone and the wall. A few are on Amazon AU, but the ones that came up were sold by bare marketplace names with thin listings, and on an NBN service with the phone plugged into the modem they're one more box and one more power supply to fail. I've also left iPhones out entirely. If a parent is ready for a smartphone instead of a home phone, the refurbished phones we sell and warranty ourselves and our guide to choosing a phone for seniors are the better starting point.

The 5 picks, $74 to $179

Prices are Amazon AU at time of writing (9 October 2026) and move week to week. Amazon AU doesn't publish a home phone category rank, so ranks are its website-wide sales rank, checked the same day; two picks had no published rank.

Side-by-side comparison

What we see fail at the bench: home phones

Home phones don't come in for repair often, because most people replace them, but they come up all the time when a family brings in a parent's tablet or mobile and mentions the phone at home stopped working too. Three faults account for nearly all of it, and two of them cost almost nothing to sort out once you know what you're looking at.

Decision tree: which one should you actually buy?

• Is the home phone their main line, and do blackouts or NBN outages worry you? → The Opel Mobile 4G Home Phone 2 at $179. It runs on 4G with a back-up battery, so it doesn't care what the modem's doing.
• Is a parent getting worn down by scam calls? → The Gigaset Comfort 600 at $119. Its trusted list lets known contacts through and stops the rotating numbers that defeat block lists.
• Want the most blocking for the least money on a normal cordless phone? → The VTech CLS22150 at $74, with a 1,000-number block list, a one-touch block key and mobile pairing.
• Do they need big buttons and simple area-code blocking together? → The Panasonic KX-TGU120AZB at $99, with large illuminated keys and Caller ID based country and area code blocking.
• Do they struggle with keypads altogether? → The Oricom CARE80S at $80. Six photo buttons, a loud earpiece and nothing to charge.
• Phone, base or modem stopped working and you can't tell which? → Bring the lot into our Erina workshop and I'll tell you which part has failed before you spend anything on a replacement.

Frequently asked questions

Do call-blocking phones stop scam calls completely?

No, and any box that says so is overselling it. A block list only stops numbers that have already called, and scammers rotate and spoof numbers constantly. Category blocking, like withheld numbers or international prefixes, catches a lot more for very little effort. The strongest setup is an allow list, where only saved contacts ring through, which the Gigaset Comfort 600 states on its listing. Combine whichever phone you buy with the blocking your telco already does in the network and the free Do Not Call Register, and most households see the nuisance calls drop sharply rather than disappear.

Will a call-blocking phone work on the NBN?

Yes, the cordless and corded picks work on an NBN voice service, plugged into the phone port on your modem rather than the wall socket. The catch is that the modem needs power, so the phone stops in a blackout unless the modem is on a battery backup. Caller ID based blocking also needs Caller ID switched on for your NBN voice service, which most providers include but a few still charge for. The two 4G phones in this guide don't use the NBN at all, so neither of those limits applies to them.

What is the best phone for an elderly parent in Australia?

It depends on two things: whether they struggle with dialling and whether the home phone is their main line. For keypad trouble, the Oricom CARE80S with photo buttons is hard to beat at $80. For scam calls, the Gigaset Comfort 600 with its trusted list. If the home phone is the main line and blackouts are a concern, the Opel 4G Home Phone 2. If they're ready for a smartphone instead, a refurbished phone with large text settings is often the better long-term answer than any home phone.

Do 4G home phones need a mobile plan?

Yes. A 4G home phone takes a SIM card and runs on the mobile network, so it needs an active service from a carrier that covers your address well. For a phone that mostly receives calls, a basic prepaid plan is usually plenty. Since the 3G networks closed in 2024 the phone must support 4G calling (VoLTE) to work at all, including for emergency calls, so avoid older 3G-era seniors phones on marketplace listings. Check indoor reception where the phone will sit before buying, because desk phones often have smaller antennas than a modern mobile.

Can I keep my existing home phone number with a 4G home phone?

Usually you can port a landline number to a mobile service, but not every carrier accepts fixed-line numbers on a mobile plan, and some will only port it to a fixed wireless or home phone product. Ask the new carrier before you cancel anything, because cancelling the old service first can lose the number. If keeping the number isn't possible, the simplest fix is a recorded message on the old line for a few weeks and telling the people who matter. Don't port a number during a week when you're expecting important calls.

Why does my cordless phone battery die so quickly?

In nearly every case it's the handset batteries wearing out, not a fault in the phone. Rechargeable cells in a cordless handset lose capacity over three to five years, especially sitting in a warm cradle all day, and eventually they can't hold a call. The other common cause is dirty or corroded charging contacts in the cradle, which stop the handset charging at all. Clean the contacts with isopropyl alcohol first, then replace the cells with the same type and capacity printed on the old ones. Never use non-rechargeable batteries in a charging cradle.
