A standard Australian ring cycle is exactly three seconds, so the familiar advice to answer within three rings means nine seconds and six rings means 18 seconds, which Skai Solutions treats as the outer limit during a service.
Almost every number published about restaurant phones is folklore, including the one about callers hanging up after 45 seconds. This page uses three things that are actually published: the Australian ring cadence specification, a census of 5.8 million hospitality calls, and a full year academic study of caller patience. It converts them into a divert timer you can set this afternoon.
Nobody counts seconds while a phone rings. They count rings, and then they guess at the seconds, and the guess is usually wrong. The Australian ring cycle is a published number, so the conversion does not have to be a guess.
NBN Co's own electrical specification for the voice interface sets the default ringing cadence as 400 milliseconds on, 200 milliseconds off, 400 milliseconds on, then 2,000 milliseconds off, repeating. That is a three second cycle, held to a tolerance of 120 milliseconds. One ring, as a caller hears it, is three seconds.
| Rings the caller hears | Seconds elapsed | What it means in a venue |
|---|---|---|
| 3 | 9 seconds | The standard advice. Achievable only if someone is already near the phone |
| 6 | 18 seconds | Realistic during service. Past this, the caller starts deciding |
| 10 | 30 seconds | Most telco no-answer diverts fire somewhere around here |
| 20 | 60 seconds | The point where measured hang-ups spike a second time |
So the familiar instruction to answer within three rings is an instruction to answer inside nine seconds. During a Friday service that is not a policy, it is a wish. Eighteen seconds is the number worth defending, because it is long enough to be achievable and short enough to sit well inside what the evidence says a caller will tolerate.
The honest answer is that nobody has measured it for Australian or New Zealand restaurants. Most of the figures circulating in this industry are folklore, including the widely repeated claim that most callers hang up after 45 seconds on hold, which traces back to an unnamed study cited by a vendor selling hold music.
Two measurements do exist and both are worth more than the folklore.
The first is sector specific. The Marchex Institute analysed 5.8 million calls to 13 hotel brands and found a 14 per cent failed call rate, calls either never answered or abandoned before they were, with 5 per cent never answered at all. Hotels are not restaurants, but they are the closest measured hospitality comparison that exists, and they are better resourced than a 40 seat bistro.
The second is the strongest evidence on caller patience anywhere: Brown, Gans, Mandelbaum and colleagues published a full year census of more than 1,200,000 calls in the Journal of the American Statistical Association in 2005. Not a survey, every call. About 20 per cent of callers who wanted service abandoned before they got it, and mean caller patience was 446 seconds, roughly seven and a half minutes.
That last number is the one that surprises people, and it is why the folklore is dangerous in both directions. Callers are far more patient than the industry claims. What the same study found, though, is that patience is not spread evenly: hang ups cluster in two spikes, one in the first few seconds as a recorded message starts, and a second at about 60 seconds when the message repeats. Sixty seconds is twenty ring cycles.
Put your own number on it rather than borrowing one. Skai Solutions' own working model, and these are assumptions rather than measurements so substitute your own: 150 missed calls a month at an average order value of A$40 is A$6,000 a month, or A$72,000 a year. If your venue takes 60 calls a week and misses one in seven, that is roughly 37 calls a month, and at A$40 each the answer is about A$1,480. The arithmetic matters more than the total.
It is almost never that nobody cares. It is that the phone competes with a person who is already holding three plates.
The pattern is consistent across venues. Calls arrive in exactly the windows when nobody can take them: the 30 minutes before a service starts, when the team is setting up, and the peak itself. The person nearest the phone is also the person nearest the pass. Answering the call means putting down food, which means a table waits, so the call loses.
The second cause is structural. Most small venues have one line and one handset, so a second caller during a first call gets a busy signal or a voicemail box. The third is that the no-answer divert timer was set once, by whoever installed the system, and has never been looked at since. If yours diverts at 30 seconds you are letting ten rings go by before anything happens, which is most of the way to the 60 second cliff.
Our page on how to answer the phone at a restaurant covers the script side of this. This page is about the seconds.
One, free: change the divert timer. Log into your phone service and set the no-answer divert to fire at 15 to 18 seconds instead of 30. That is five or six rings rather than ten. It costs nothing and it is the single highest yield change on this list, because it moves every unanswered call to wherever you actually want it to land before the caller has started to lose interest.
Two, free: shorten the greeting. If a recorded message plays before a human can answer, cut it to one sentence. The measured hang up spike in the first few seconds is a spike of people reacting to a recording where they expected a person. A 20 second welcome message with your opening hours in it is not information, it is an exit.
Three, low cost: move the handset or add a second one. A cordless handset at the pass costs less than one no show. The reason the phone rings out is usually distance, not willingness.
Four, paid: put something behind the phone that always answers. That is either a message taking service, which takes a name and a number, or an AI phone agent, which can take the booking itself. Our comparison of the cheapest ways to answer a restaurant phone prices these side by side, and answering service costs in Australia covers the market rates.
Then the problem is volume, not process, and you should stop trying to fix it with discipline. A venue taking more than about 15 calls in a two hour service is not going to answer them all with the staff on the floor, and telling the team to try harder produces a worse dining room rather than a better phone.
Be honest about which category you are in before you spend anything. If your phone mostly carries enquiries, opening hours, do you have a table tonight, are you open Monday, then a basic message taking plan is the right buy and it is not us. Those questions do not need a booking made, they need an answer given, and paying for booking capability you never use is waste.
If your phone carries bookings, changes, large group enquiries and orders, then the difference matters, because a message is not a booking. Somebody still has to call back, and the callback happens after service when the caller has already booked elsewhere. An AI receptionist answers on the first cycle and completes the booking in the conversation. Setup at Skai Solutions takes five days.
Whatever you choose, measure it. Ask your phone provider for a call report showing answered and unanswered calls by hour. Almost every provider has one and almost nobody asks. You cannot argue about the phone until you know how many calls it drops and when.
Fifteen to eighteen seconds, which is five to six rings, for a venue where a human usually answers. The call then moves on while the caller is still listening rather than while they are reaching for a competitor.
Longer, up to about 30 seconds, only if the divert goes somewhere worse than the phone itself, for example a voicemail box nobody clears. In that case the extra rings genuinely do give a staff member a chance. If the divert goes somewhere that always answers, there is no argument for making the caller wait at all: shorter is strictly better.
Never set it past 60 seconds. That is twenty ring cycles and it is past the point where the measured evidence shows a second wave of people giving up. Related reading: what no shows cost and what a restaurant receptionist actually does.
Is three rings really the standard? It is the standard piece of advice, not a rule, and it comes from hotel front desk training rather than from any measurement of callers. At three seconds a ring it means nine seconds, which is an unrealistic target for a venue in service.
Do callers really wait seven minutes? On average, in the call centre census above, yes, but that average hides the two spikes. Mean patience is a poor guide to any individual caller and you should plan against the spikes rather than the mean.
Does a ring cycle differ by carrier? The three second cadence is the default specified for the standard voice interface. A hosted or app based phone system can present something different to the caller, so if yours sounds unusual, time it with a stopwatch rather than assuming.
What about calls that arrive while we are on another call? Those never ring out, they fail instantly, which is worse and invisible. Ask for the call report; engaged and unanswered are counted separately.
