Call routing is the set of rules that decides where each incoming call goes: your mobile, a teammate, voicemail or someone who answers for you. For a trade business, the best setup is one where every call is answered by a person or system that can take the job details, whatever the hour and wherever you are working. That is what Kūmara, our AI receptionist for Kiwi tradies, does: it answers business calls 24/7, books jobs and emails the details to your calendar. Below is how the options work, where each one fails on a busy day, and how to choose.
TL;DR
- Call routing sends each call to a mobile, a team member, a menu or voicemail using rules such as time of day, who is free and what the caller needs.
- Simple forwarding to your mobile fails exactly when you are up a ladder or under a house. Routing needs a final step where someone or something always answers.
- Multi-trade businesses need to sort callers by trade or urgency before anyone picks up, so nobody has to transfer a caller who has already explained the problem.
- Voicemail captures a message only if the customer is willing to leave one. A 24/7 answering service captures the job details and books the visit.
- Kūmara handles the answering and booking for NZ trades, with plans from NZ$249 per month.

What call routing actually is
When a customer rings your business number, something has to decide what happens next. Call routing is that decision, made by rules you set in advance. Common rules use caller details, business hours and who is available to send the call to a person, a department or voicemail.
For a big company that means a call centre. For a sole-trader plumber or a five-person electrical crew it means something simpler: who rings first, what happens after 20 seconds, and what happens at 6pm or on a public holiday.
The problem is not technical. A tradie's work takes them away from the phone for hours. A customer with a burst pipe or a dead switchboard rings the next business on the list if yours goes unanswered. Routing is how you make sure a call lands somewhere useful.
The main routing options, from simplest to most capable
Most small-business routing is built from the same handful of pieces. Phone providers use different names, but the ideas are the same.
Forward everything to one number
All calls to your business line ring your mobile. It is quick to set up and keeps your published number. It works until you are on another call, in a roof space with no reception or at the dentist.
Forward only when you don't answer, or are busy
Conditional forwarding sends the call elsewhere only if you do not pick up within a set time, or if your line is engaged. The Spark business guide describes three types of diversion on its business lines: immediate (all calls), busy, and no answer. The weak point is the destination. If the second number is also a busy person, you have only moved the missed call.
Ring several people
When you have a crew, you can ring everyone at once and let the first person to pick up take the call, or ring people one after another in a set order. Ringing all at once is the usual starting point because the call is answered by whoever is free. Ringing in order is better when a particular person should get first go, such as the office manager, then the senior installer, then a backup.
The catch for trades is that everyone on a crew is usually on a job at the same time. Ringing four people who are all on site is still a missed call.
Time-based rules
Rules can change by the clock: calls ring the crew during work hours, go to a mobile on-call number over lunch, and go to voicemail with a text back after 5:30pm. You can also set a different greeting for public holidays. Time rules are essential for trades, because your busiest enquiry periods, early morning and after work, are often when you are driving or on site.
A phone menu
A menu (sometimes called an auto attendant or IVR) plays a greeting and asks callers to press a key: "1 for a quote, 2 for an existing job, 3 for an emergency." It stops callers landing with the wrong person. Many customers dislike menus, so keep them to three options at most, and make the first one the most common reason people call.
A receptionist who answers for you
The last option is to hand the call to a receptionist, human or AI, who answers every call, asks the right questions and passes on the job. This is the only option on the list that captures job details when nobody on your team is free.
How to forward your calls to your mobile in NZ
If you are still using a landline-style business number, forwarding is the starting point, and it takes two minutes. On a Spark business line, the steps are:
- Lift the handset and dial 181.
- Dial a slot number between 161 and 169. Each slot is a separate diversion, so you can set up different types.
- Dial the destination number, including the area code.
- Press # and wait for the long-short-long confirmation tone.
Spark also lets a business divert its landline number to a mobile, a mailbox or a call minder, so you keep the number on your van and website while the calls go where you are. Other providers have their own codes or an online portal, so check your provider's page for the exact method.
Two habits save you grief. First, set a "no answer" diversion in addition to an "always" diversion, so a call that rings out goes somewhere. Second, ring your business number from a different phone after any change, to hear what a customer would hear.
Forwarding gets the call to your phone. It does not answer it when you can't, and that gap is where jobs are lost. Kūmara picks up at that point: it answers 24/7, captures the caller and job details and emails the booking summary to your calendar.
Routing calls when you run more than one trade
A business that does plumbing, gasfitting and drainlaying, or electrical and heat pump installation, has a routing problem that a sole trader does not. Different calls need different people, different questions and different urgency.
The usual solution is a menu to split callers by trade, combined with time rules for after hours and specific dates. A caller presses a key for the service they need, and a timeout path decides what happens if they press nothing. Calls then go to the right person or crew, with a different path after hours.
The benefit goes beyond tidiness. A customer who rings about an invoice and reaches the installer has to be transferred, repeat themselves, and sometimes gets cut off in the transfer. Sorting the call before anyone answers means fewer wasted calls and fewer effective missed ones.
The hard part is keeping the rules current. People change roles, a crew member goes on leave, a trade has a busy season. A menu with five options and four phone numbers becomes a maintenance job of its own.
With Kūmara, workflows are customisable for multiple trades, and you control your hours, scripts, pricing and how urgent calls are handled. The receptionist asks the questions that suit each trade, rather than sending the customer through a menu to find the right person. We have dedicated pages for plumbers, electricians, gasfitters and heat pump and HVAC installers, and a full list at every trade that books site visits.
Handling urgent calls and after hours
Urgent calls are the ones where routing matters most. A homeowner with water coming through a ceiling, a gas smell or no power does not leave a voicemail and wait. They ring until someone answers.
A sound after-hours plan answers three questions:
- What counts as urgent? Write it down. A leaking tap can wait until morning; a burst pipe cannot. Your answer sets which calls reach your mobile at 10pm and which are booked for the next day.
- Who is on call? Decide who takes urgent calls after hours, and treat it as a deliberate roster. Sending every after-hours call to one person's personal mobile wears people out.
- What does everyone else hear? A professional greeting that tells the caller what happens next is better than silence or a full mailbox.
A receptionist that applies your urgency rules solves the on-call problem. Kūmara manages urgent requests according to the rules you set, so the calls that need you straight away are flagged, and routine enquiries become bookings without waking anyone up.
Voicemail, forwarding, a menu or 24/7 answering: how to choose
Each option answers a different question. Here is how they compare for a trade business.
| Option | Best for | Where it breaks down on a busy day |
|---|---|---|
| Voicemail | Low call volume, non-urgent work | Many callers hang up rather than leave a message, and you still have to ring back |
| Forwarding to your mobile | Sole traders who are usually reachable | Unanswered when you are on another call, on a roof or out of coverage |
| Ring group or ring order | Crews with someone often in the office | Everyone is on site at the same time |
| Phone menu | Multi-trade businesses with separate people for each trade | Callers dislike menus, and the rules need constant upkeep |
| 24/7 call answering | Any trade where a missed call is a lost job | Needs your hours, scripts and urgent rules set up properly once |
The pattern is clear: the first four options decide where a call goes, but only the last one makes sure it is answered and the job details are captured. That is why many trades stack them, with forwarding or a ring order first and an answering service as the guaranteed final step.
To choose, ask yourself three questions:
- How many calls do I miss in a typical week? Your provider's call log or your phone's missed-call list shows this. Reporting is what makes a missed-call problem visible: it shows how many calls are missed, when the busiest periods fall and whether callers wait too long.
- What is one job worth? If a single call can be a hot water cylinder, a rewire or a bathroom reno, a missed call costs far more than a monthly subscription.
- Who is on the tools at the same time? The more of your crew is out at once, the less a ring group helps and the more you need someone who always answers.

A simple routing plan for a trade business
Whether you build it yourself or use an answering service, work through the same plan:
- List your call types. New quote, existing job, supplier, emergency, wrong number. Rank them by how much money or risk each carries.
- Set your hours. Decide when a human answers, when calls go elsewhere and what happens on public holidays.
- Choose the first responder. For a sole trader, that is your mobile. For a crew, it is whoever is free or an office contact.
- Add a guaranteed last step. The final destination should always capture the caller's name, number, address and the problem. Without that step, the call is only moved, not answered.
- Write the urgent rules. Say exactly which situations are passed to you immediately.
- Check it from outside. Ring from a number that is not in your phone, at different times, and listen to what the customer experiences.
- Review monthly. Look at missed calls and adjust.
With Kūmara, steps 2 to 5 become part of your setup: your hours, scripts, pricing and urgent-call handling are customisable, and the done-for-you setup option is available for NZ$299 if you would rather not configure it yourself.
FAQ
What is the best way to forward calls when I'm on a job?
Use conditional forwarding so calls go to your mobile and, if you don't answer, to a second destination that always picks up. On a Spark business line you dial 181, a slot number from 161 to 169, then the destination number. A 24/7 receptionist such as Kūmara can be that second destination, answering the call and booking the job.
How do I handle calls for multiple trades?
Sort callers by trade before anyone answers, either with a menu or with a receptionist that asks what the job is. Then route each call to the right person, with separate after-hours rules for each trade. Kūmara's workflows are customisable for multiple trades, so the questions suit each one.
Is voicemail enough for a small trade business?
Voicemail works for low-volume, non-urgent work, but a caller with a burst pipe or a faulty switchboard wants an answer straight away. A receptionist that answers and captures the job details means you are not relying on the caller to leave a message and wait for your call back.
How much does a 24/7 answering service for tradies cost?
Kūmara's Solo plan is NZ$249 per month, or NZ$2,490 per year. Crew is NZ$549 per month, and Business is NZ$999 per month. A done-for-you setup is NZ$299 one-off. Current plans are on the pricing page.
