How to forward your business line to an answering service when you are on a job

On this page
Quick answer
To forward business calls to answering service while you're on a job, switch on call forwarding for your business line and enter the number the service gives you. As of October 2026, the exact steps depend on your carrier, so check its help page. NanoFlow can answer those calls too. See how it works for home service businesses.
At a glance
- A customer dials the number on your van, your website or your Google Business Profile.
- Do it on a quiet evening, well before you leave for a job.
- Put these to your carrier before you rely on forwarding every day.
- Borrow a phone that isn't on your account and set aside a few minutes.
- Forwarding only gets the call to the service.
Call forwarding is a phone setting that passes calls made to your number on to another number you choose. If you're under a sink, up a ladder or halfway through a client's color, that other number can be an answering service, a team member or an assistant that picks up for you.
What call forwarding does on a working day
A customer dials the number on your van, your website or your Google Business Profile. Your line passes the call along. Someone picks up with your business name and writes down what the caller needs.
Carriers can offer more than one way to forward, and they don't always use the same names for them. So ask yours which of these your line supports.
Forward every call
Every call goes to the other number. This fits a day off, a holiday, or a long day on a big install when you know you won't touch the phone at all.
Forward only the calls you miss
Calls pass along only when you don't pick up, when you're already on another call, or when your phone can't be reached. Carriers may name these options differently, so describe what you want in plain words when you ask.
On a normal workday this is the one to ask about. You keep the calls you have a free hand for, and the rest still get answered.
How do I forward my business calls when I'm on a job?
Do it on a quiet evening, well before you leave for a job. Work through it in this order.
- Get the forwarding number from your answering service, and confirm they have your business name and call notes ready.
- Find your carrier's own instructions, using the notes below.
- Switch on the option you picked.
- Test it from another phone.
- Save the steps to switch it off.
Verizon
Search for Verizon call forwarding and open the result on verizon.com, so the steps come from Verizon itself. Write down three things from the page. How to forward every call. How to forward only the calls you miss. And how to turn forwarding off. If the page doesn't cover all three for your phone, call Verizon support and describe what you want.
AT&T
Run the same search for AT&T and open the result on att.com. If the page shows more than one method, such as a switch in your phone's settings and a code you dial, check which method forwards every call and which forwards only missed calls. Use the one that matches the option you picked. If you're unsure, ask AT&T support before you rely on it.
T-Mobile
Search for T-Mobile call forwarding and open the result on t-mobile.com. Look for the steps that match your phone, iPhone or Android, since the menus can differ. Copy the steps to turn forwarding off as well. If what's on your screen doesn't match the page, ask T-Mobile support and skip the guesswork.
A landline or VoIP number
If your business number sits with a landline company or an internet phone provider, ask them the same questions. Find out where forwarding is set, on the handset, in an online account or through support. And ask whether it can follow your opening hours, so you're not switching it by hand every evening.
Questions to ask your carrier first
Put these to your carrier before you rely on forwarding every day.
- Does forwarding cost anything on my plan, and do forwarded calls use my minutes?
- Which forwarding options does my line support?
- If I don't answer, does the call go to my voicemail or to the forwarded number?
- How do I check whether forwarding is on right now?
- How do I switch it off again?
Save the answers in your phone notes next to the steps. You'll want them on the day something feels off, and that's rarely a day you have time to search.
Test it before a customer does
Borrow a phone that isn't on your account and set aside a few minutes.
- Call your business number and let it ring. It should reach the answering service.
- Call again while you're on another call, if you switched on that option.
- Put your phone in airplane mode and call once more.
- Ask the service what they took down. Did they get your business name right, plus the caller's number and the message?
If any test ends in your voicemail, a dead line or the wrong greeting, go back to your carrier's page or support before you trust it with a real customer. Then test again after any phone update or plan change.
Brief the answering service
Forwarding only gets the call to the service. What happens next depends on what you tell them.
Give them a short call script
Write down your business name the way you say it on the phone. List the jobs you take and the ones you don't. Add your service area. Then spell out what counts as urgent for you, like a burst pipe, no heat in a cold snap, a roof leaking during rain or an outlet that's sparking.
Decide how messages reach you
A text you can read between jobs is easier to act on than an email you'll open tonight. Ask for the caller's name, number and address, the problem in their own words, and how soon they need someone. One message per call keeps things tidy.
Agree on what they can promise
Can they book a slot? Mention a call out fee? Or only take a message? Put the answer in writing. A service that knows its limits won't promise a caller something you never offered.
Make forwarding part of your daily routine
Forwarding left on by accident is easy to miss, because your phone just goes quiet. So build it into the day.
If you forward every call, switch it on when you close or start a long job, and switch it off when you're free again. If you forward only missed calls, ask your carrier whether you can leave it on, and test it now and then.
Tell anyone else who answers your line which setting is on. A quick note in the van or the shop saves a confused morning.
Where NanoFlow fits
Once a forwarded call is answered, you still have the follow up to handle, like a callback, a quote or a slot in the schedule. That part can pile up by the end of a long day.
NanoFlow is the business AI assistant for people who'd rather be working. It answers the calls you can't take, when you're busy or closed. It also sorts your inbox, handles your reviews, chats with visitors on your website and turns finished jobs into reels and carousels in your own voice. It connects to Housecall Pro, Jobber, Google Business Profile and your email. Nothing goes out until you approve it.
If you want to see how it would deal with your missed calls, read what NanoFlow does or talk to the NanoFlow team.
Frequently asked questions
Will my phone still ring if I forward my calls?
That depends on the forwarding option you pick. Ask your carrier which options your line has and which one rings you first before passing the call on. Then test it from another phone so you know for sure.
Will forwarding calls cost me anything?
Ask your carrier how forwarded calls are billed on your plan before you rely on forwarding every day. Write the answer down next to the steps you were given.
How do I switch forwarding off again?
Get the off steps from your carrier when you set it up, and save them in your phone notes. After switching off, call your number from another phone to make sure it rings you normally.
Can the answering service book jobs for me?
Only if you agree that with them. Tell the service in writing what they can promise callers, such as a booked slot or only a callback, so nobody hears an offer you never made.
