Short answer
How do I set up emergency call routing for a contractor business?
To set up emergency call routing for a contractor business: (1) forward your business number to a 24/7 AI receptionist or trained dispatcher; (2) configure trade-specific triage questions for your top emergencies (HVAC: gas smell, no heat; plumbing: burst pipe, sewer backup; electrical: panel down, sparking); (3) set urgency thresholds that trigger an immediate email to the on-call tech with full job context. OnCrew automates all three with a 14-day free trial at $49/month.
- Forward your business number to a 24/7 AI answering line (or a trained dispatcher) so no emergency call rolls to voicemail. Most carriers support conditional forwarding (busy / no-answer / after-hours) in the portal.
- Configure trade-specific triage so the intake asks the right urgency questions for your top emergencies: HVAC (gas smell, CO, no heat in winter, no AC in extreme heat), plumbing (burst pipe, sewer backup, water heater leak), electrical (panel down, sparking, burning smell), roofing (active interior leak, structural damage).
- Set urgency thresholds that trigger an immediate email to the on-call tech with the full job context: caller name, callback number, service address, problem in plain language, and a clean transcript. Non-urgent calls get a calendar request instead of a 2am page.
Step-by-step setup checklist for each carrier is below. Related reading: answering service setup checklist and answering service for plumbers.
What call forwarding actually means for a contractor
Call forwarding is a setting on your existing phone line that sends incoming calls somewhere else. For contractors, the goal is simple: keep your business number on every truck, sign, Google Business Profile, and ad, and route forwarded calls to an answering flow in your business voice when the forwarding rule sends them to OnCrew.
When you forward your line to OnCrew, callers still dial the number you have always used. The forwarding rule you choose decides which calls reach the AI and which calls keep ringing the way they do now. You stay in control of the rule, and you can change it from your carrier portal or a standard handset code at any time. Forwarding never moves your number, and the guided setup helps you configure forwarding from the provider that already hosts your line.
What stays the same
- Your business number on trucks, signs, and Google
- Your carrier and your phone system
- How customers dial and reach you
What changes for the caller
- An AI receptionist greets in your business name
- The right questions for your trade get asked
- Urgent jobs trigger a callback alert to your team
Forward-all, after-hours, or overflow
The three forwarding modes most contractors use. Pick the one that matches how your shop already answers the phone. You can change it later without changing your number.
Forward all calls
Best when you are solo, fully booked on jobsites, or want forwarded callers to reach an answering flow in your business voice while you are working.
Best fit
Solo operators, owner-operators between jobs, and teams without a dedicated office phone person.
What callers experience
Forwarded calls reach OnCrew instead of rolling to voicemail. You can still take a call live if you choose to ring your cell first and only forward on no-answer.
Forward after-hours and weekends
Best when you have someone answering during business hours and want clean coverage at night, on weekends, and on holidays.
Best fit
Shops with a daytime office or front-desk person who already handles the easy calls.
What callers experience
Your existing phone keeps ringing in the office during the day. After hours, weekends, and holidays roll into OnCrew automatically.
Forward overflow on busy or no-answer
Best when you only want to catch calls that would otherwise be missed instead of routing every caller through the AI.
Best fit
Growing shops that want voicemail-bound calls handled without changing the experience for callers who already get through.
What callers experience
Your office line rings first. If a call goes unanswered or the line is busy, it forwards to OnCrew so the caller still hears a real conversation.
Configure forwarding in six steps
A practical setup pass that works whether you are forwarding from a cell carrier, a hosted VoIP provider, or an office PBX. If you would rather not solo it, call (818) 578-4783 and Sarah can set your line up with you on the call.
Confirm your business number and current voicemail flow
Write down the business number you want callers to keep dialing, your current ring time, and where the call goes today (cell, office desk phone, voicemail, or a service).
Pick your forwarding mode
Decide whether you want forward-all, after-hours and weekends, or overflow on busy or no-answer. The mode you pick changes which forwarding code or carrier setting you will use.
Get your forwarding target from OnCrew
Once your trial is set up, OnCrew gives you a forwarding target to point your number at. You configure forwarding from your existing carrier or PBX, and your number stays where it is. OnCrew moves (ports) a number only on request, when it lives in an app that cannot forward calls, such as Sideline, Index or TextFree.
Configure forwarding on your existing line
Use your carrier portal, business phone system, or the standard call-forwarding codes from your handset. Common patterns are unconditional forward (forward-all), conditional forward on no-answer or busy (overflow), and time-of-day forward (after-hours).
Lower your no-answer ring count if forwarding on overflow
If you forward on no-answer, set the rings to a low number such as 3 to 4 rings. Most callers hang up after 5 rings, so a long ring count means the AI never gets the call.
Tell your team what changed
Let your crew know callers may now hear a friendly AI receptionist on your business line. The AI greets in your business name, asks the right questions, and alerts the on-call person on your configured alert channel for urgent jobs.
Not sure which forwarding code your carrier uses?
Cell carriers and VoIP providers each use different patterns for unconditional, no-answer, busy, and time-of-day (after-hours) forwarding. The OnCrew team has walked through forwarding with the HVAC answering service page , plumbing, electrical, and roofing contractors on common carriers and VoIP providers and can guide you through the right setting for your line.
Where the forwarding setting lives in your phone system
Cell carriers and most landlines take a dial code. Office phone systems such as Verizon One Talk or RingCentral forward from their own portal or app instead. These steps follow each provider's own help pages. XXXXXXXXXX stands for the 10-digit OnCrew number you get at setup.
Cell phone carriers
Verizon
Calls you do not answer: dial *71XXXXXXXXXX (turn it off with *73). Forwards the calls you don't answer to OnCrew. Verizon forwarding can only be managed from the phone itself.
Every call: dial *72XXXXXXXXXX (turn it off with *73). Forwards every call to OnCrew, so your phone stops ringing for business calls.
Visible, Straight Talk, Total Wireless and Tracfone run on Verizon's network and take the same codes. If this number rings desk phones in an office, it is most likely Verizon One Talk: use that guide under Office phone systems instead, because its forwarding is set in the One Talk portal.
AT&T
Calls you do not answer: dial **004*1XXXXXXXXXX# (turn it off with ##004#). Forwards the calls you don't answer, decline, or miss with no signal to OnCrew; dial it like a phone number and press call. These are the standard network codes AT&T phones accept; if yours rejects it, dial *61*1XXXXXXXXXX# instead (calls you don't answer only), or use the menu path below.
Every call: dial *21*1XXXXXXXXXX# (turn it off with #21#). Forwards every call to OnCrew. On an iPhone, Settings, then Phone, then Call Forwarding does the same thing.
- Android: in the Phone app open Settings, then Calling accounts, pick your SIM, tap Call forwarding, then When unanswered, and enter the number.
- iPhone: Settings, then Phone, then Call Forwarding only forwards every call. For missed calls only, dial the code above, or call 611 and ask AT&T to turn on no-answer forwarding to your OnCrew number.
Cricket, Consumer Cellular, H2O and Red Pocket run on AT&T's network and take the same codes.
T-Mobile
Calls you do not answer: dial **004*1XXXXXXXXXX# (turn it off with ##004#). Forwards the calls you don't answer, decline, or miss with no signal to OnCrew. If the phone still refuses it with Wi-Fi calling off, dial **61*1XXXXXXXXXX# instead (calls you don't answer only). To ring longer before forwarding, dial **61*1XXXXXXXXXX**20# after it (5 to 30 seconds).
Every call: dial **21*1XXXXXXXXXX# (turn it off with ##21#). Forwards every call to OnCrew, so your phone stops ringing for business calls.
Metro, Mint, Boost, Ultra Mobile, Google Fi, US Mobile, Tello and Simple Mobile run on T-Mobile's network and take the same codes. If the phone says it cannot process the request, turn off Wi-Fi calling and dial the code again.
Landline or office phone
Verizon landline
Calls you do not answer: dial *92 (turn it off with *93). Turns on forwarding for calls you don't answer; *90 covers calls while your line is busy. On most Verizon landlines the forward-to number is set at their business office, so if the code does not take, ask Verizon to point no-answer forwarding at your OnCrew number.
Verizon Fios
Fios Digital Voice is managed online: sign in to My Verizon, open Account Manager, then Calling Features. Locate Me rings your phones in order before sending the call on, Simultaneous Ring rings your OnCrew number alongside your phone, and Call Forwarding sends every call straight to OnCrew.
AT&T digital phone (U-verse)
Calls you do not answer: dial *92XXXXXXXXXX# (turn it off with *93#). No Answer Call Forwarding sends your missed calls to OnCrew. *90 plus the number and # forwards calls while your line is busy; *72 forwards every call.
AT&T landline
- Call AT&T at 800.288.2020 and ask for no-answer call forwarding to your OnCrew number; on traditional AT&T lines an agent turns this on.
- To set how long your phone rings first, dial *47, then at the second dial tone 18 for three rings or 24 for four.
Xfinity Voice
Every call: dial *72XXXXXXXXXX (turn it off with *73). Basic Call Forwarding from your handset: every call goes straight to OnCrew.
On a Comcast Business line, use Comcast Business Voice and VoiceEdge under Office phone systems instead: it has a no-answer code. Xfinity has no busy or no-answer dial codes. Sign in at xfinity.com or in the Xfinity app and open Xfinity Voice settings, then Call Forwarding. Advanced Call Forwarding rings OnCrew alongside your home phone and lets you set the rings before voicemail; Basic Call Forwarding (*72 from your handset, *73 to stop) sends every call straight to OnCrew.
Blue Ridge Communications
- Dial *72, press 1, then enter 1XXXXXXXXXX (the 11-digit number), and press #. You'll hear a confirmation, and every call now forwards to OnCrew.
- To turn forwarding off, dial *72 and press 1 again, then wait for the confirmation beeps. Blue Ridge does not use *73.
- Prefer to do it online: sign in to the My Blue Ridge app or website, hover over your phone line and click Edit, open Call Handling, then the Forward All tab, enter the 11-digit number, and Save.
Blue Ridge forwards every call (it has no forward-only-missed-calls option), so callers reach your receptionist directly instead of ringing your line first. Then tap Test it for me on your forwarding page and OnCrew rings your business number to confirm the calls reach Sarah.
Spectrum (home or business)
Every call: dial *72XXXXXXXXXX (turn it off with *73). Forwards every call to OnCrew, personal ones included.
- Sign in at spectrum.net, open Voice, then Call Forwarding, and set No Answer forwarding to your OnCrew number. Only the calls you miss go to OnCrew; your phone still rings first.
- No Call Forwarding option in your account? Reply to any OnCrew email and we will set it with you.
Spectrum's dial code *72XXXXXXXXXX forwards EVERY call to OnCrew, including personal ones, so your phone stops ringing entirely. Use it only if that is what you want; *73 turns it off.
Spectrum Business Voice
Calls you do not answer: dial *92 (turn it off with *93). Pick up a phone on your Spectrum Business line, press *92, and at the dial tone enter XXXXXXXXXX, press #, and wait for the confirmation. Only the calls nobody answers go to OnCrew; your phones still ring first.
Every call: dial *72XXXXXXXXXX (turn it off with *73). Forwards every call to OnCrew, so your phones stop ringing for business calls.
- Online instead: sign in to your Spectrum Business account, open Voice (Voice Manager), then Call Forwarding, set No Answer forwarding to your OnCrew number, and save.
- If *92 gives an error tone, the feature is not switched on for your line yet: turn it on under the same Call Forwarding settings, or reply to any OnCrew text and we sort it out with you.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
On a Spectrum home phone line, pick Spectrum (home or business) on this page instead: its no-answer forwarding is set at spectrum.net.
CenturyLink (Lumen)
Calls you do not answer: dial *92 (turn it off with *93). Pick up a phone on your CenturyLink line, press *92, and at the dial tone enter XXXXXXXXXX, then wait for the confirmation. Only the calls nobody answers go to OnCrew; your phones still ring first.
Every call: dial *72XXXXXXXXXX (turn it off with *73). Forwards every call to OnCrew, so your phones stop ringing for business calls.
- If *92 does nothing, no-answer forwarding is not on your line yet: CenturyLink adds Call Forwarding No Answer when you ask (from your business account or by phone), or reply to any OnCrew text and we sort it out with you.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
Office phone systems
Verizon One Talk
- Sign in to the One Talk portal from Verizon My Business. The person who manages your Verizon business account has this login.
- Open Call Forwarding for the line your customers call and choose No Answer, so your phones ring first. Turn it on, enter your OnCrew number as the phone number to forward to, and click Submit.
- Verizon forwards after 5 rings (about 30 seconds) unless you change the number of rings in the same place. Verizon notes that with fewer than 5 rings a call can forward before your phone rings.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, choose Always instead of No Answer. Group in the same menu forwards several lines to your OnCrew number at once, all the time or on a schedule.
Grasshopper
- Sign in to the Grasshopper admin portal, open Call management, then Extensions, and click the edit icon next to the extension that takes your business calls.
- Under Call forwarding numbers choose Add call forwarding. Enter your OnCrew number in Forward incoming calls to, set Status to Active, and set Call handling to Calls will connect as soon as you pick up. The other two Call handling choices announce the call and ask whoever answers to press 1, and Sarah cannot press it.
- Keep your own phone listed above it. Choose Ring in specific order with the ring pattern Once per number in the pre-determined order above, set Ring duration on your own phone to about 25 seconds (the lowest Grasshopper recommends), and save.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, make your OnCrew number the only Active forwarding number on that extension. On the True Solo plan an extension takes a single forwarding number, so every-call forwarding is the only option there.
Quo (formerly OpenPhone)
- In the Quo web or desktop app open Settings, click Phone numbers under Workspace, select your business number, and click Edit call flow. The phone app cannot edit a call flow.
- Keep the Ring users step so your team rings first (Quo rings 30 seconds in total by default and recommends no less than 15), then drag a Forward call step directly below it and enter your OnCrew number.
- Publish the call flow and check that it shows as Live.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
Forwarding unanswered calls is on Quo's Business and Scale plans, and only a workspace owner, an admin or the number's owner can change a call flow. To send every call to Sarah, pick Forward all calls in the Default call flow dropdown, enter your OnCrew number, and enable that call flow. Quo shows Sarah the caller's own number.
GoTo Connect
- In the GoTo desktop or web app click your profile picture, then Settings, then Voice, then Find me follow me.
- Set Ring Time to how long your own phones should ring (GoTo counts about 5 seconds a ring, so 20 seconds is about 4 rings). Set No answer, send to to External and enter your OnCrew number. Keep Call Screening on Direct connect: the other choices make whoever answers accept the call first, and Sarah cannot.
- If your main number rings a dial plan or a ring group instead of one person's line, a GoTo admin makes the change: in GoTo Admin open Phone system, then Dial plans, connect an External number node with your OnCrew number to the timeout of the Simple dial node, and leave Confirm call pickup off.
- Save, then tap Test it for me on this page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah from a GoTo desk phone or app: dial *72, wait for the dial tone, enter XXXXXXXXXX, and hang up. Dial *73 to turn it off.
Nextiva
- Log in to the Nextiva voice portal as an administrator, click Users, hover over the person whose phone takes your calls, click Actions (or the three dots), and choose Voice Settings.
- Click Forwarding on the left and open Call forward (unanswered). Type XXXXXXXXXX in PHONE NUMBER with no dashes or spaces, pick how many rings under RINGS, click Save, and make sure the switch beside it is On.
- If your main number goes to a team or a call flow instead of one person, that setting does not catch those calls. Set Call forward (unanswered) under the team's Voice Settings, then Forwarding, or add a Transfer Out step to XXXXXXXXXX after the ring step in the call flow.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, use Call forward (always) in the same place. From a Nextiva phone, *92 followed by the number turns no-answer forwarding on and *93 turns it off; *72 and *73 do the same for every call. If you ever add your OnCrew number to Simultaneous Ring or Sequential Ring, leave Answer Confirmation unchecked: it makes whoever answers confirm the call, and Sarah cannot.
8x8
- Log in to 8x8 Admin Console, click Users, click the pencil icon next to the person whose line takes your calls, and open Call forwarding rules.
- Make sure Forward all calls is not checked. Check When user does not answer the call within 15 seconds and click its pencil icon. Set When no answer for (seconds) to how long your phones should ring (about 5 seconds a ring), choose Forward directly to, and enter +1XXXXXXXXXX. 8x8 asks for the country code on outside numbers.
- Click Save, then Save again on the user profile. If your main number rings a Ring Group, set the same number under Ring Groups, Call Forwarding Rules, When no one in ring group answers.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, edit Forward all calls in the same list instead. A Ring Group or Auto Attendant can only forward outside 8x8 when it, or its site, has its own phone number assigned; without one, callers get a busy signal. Forwarding set on the desk phone itself overrides these rules and does not show in Admin Console, so 8x8 recommends setting it here.
Dialpad
- First ask Dialpad Support to turn on call routing to an outside phone number for your account. Dialpad's help pages say this has to be enabled before an external number can be used.
- Then open Admin Settings, Office, Main Line, Business Hours & Call Routing, and click Edit Call Routing. Leave your operators ringing first, set the Ring Duration slider (Dialpad says 15 seconds is about 4 rings), and under Fallback Options pick To a team member, room phone, or external number. Enter your OnCrew number and click Save.
- Do not add your OnCrew number as a forwarding number under Your Devices. Dialpad asks whoever answers those calls to press 1, says that prompt cannot be switched off, and Sarah cannot press it.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, choose No operator under Call Routing and route To a team member/room phone/number. Open hours and closed hours are set separately.
Ooma Office
- Your Ooma administrator signs in at office.ooma.com, opens Settings, picks Shared External Line from the ADD menu, enters your OnCrew number, and saves. Leave Required key press on answer unchecked: it makes whoever answers press 1, and Sarah cannot. Shared External Line is part of Ooma's Pro Plus plan.
- Open Settings, then Call Handling, for the extension that answers your main number. Keep When I receive a call on Ring all devices simultaneously, set how long your phones ring under Ring for (Ooma's default is 12 seconds, about two rings), choose the shared external line under Then send to, and save.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
On Ooma's other plans only every-call forwarding is documented: from an Ooma phone dial *72, then XXXXXXXXXX, then #, and dial *73 to turn it off. Where Ooma offers a Show choice for forwarded calls, pick the original caller's number so Sarah sees who is calling.
Zoom Phone
- Sign in to the Zoom web portal, click Zoom Phone, open the Settings tab, and click Edit next to Call Handling in the Business Hours section.
- Click Add Phone Number, pick the right Country/Region, enter your OnCrew number, and save. Make sure Require to press 1 before connecting the call is unchecked, because Sarah cannot press it.
- Set Call Handling Ring Mode to Sequential, keep your desk phones and Zoom apps above the new number, and choose the Ringing Duration for Each Device. Repeat under Closed Hours if after-hours calls should reach her too.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
If your main number rings a call queue, members' outside numbers always get the press 1 prompt, so use the queue's own Overflow setting instead: Route to, Phone Number, your OnCrew number. If outside numbers are locked, your Zoom admin controls that under the Call Forwarding to External Numbers policy.
Comcast Business Voice and VoiceEdge
Calls you do not answer: dial *92 (turn it off with *93). Pick up your Comcast Business phone, press *92, and at the second dial tone (VoiceEdge: the voice prompt) dial XXXXXXXXXX, then wait for the confirmation. This forwards only the calls nobody answers.
Every call: dial *72 (turn it off with *73). Every call: press *72 and dial XXXXXXXXXX. On Business Voice, stay on the line until Sarah answers, which completes the setup.
- Online instead: sign in to My Account at business.comcast.com. Business Voice: open Phone, expand Features, select Call Forwarding, switch Call Forwarding No Answer on, select Edit, enter your OnCrew number, and save. VoiceEdge: choose Business VoiceEdge User, expand Feature Settings, select Call Forwarding, turn Call Forwarding No Answer On, and enter the number with the pencil icon.
- In the same place, Number of rings before forwarding sets how long your phones ring first.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
Comcast says not to turn on Call Forwarding No Answer on a phone that belongs to a Hunt Group; for a Hunt Group, a VoiceEdge admin sets the group's No Answer Settings instead. If *92 gives an error tone, your line may be a home Xfinity Voice line, which has no no-answer code: pick Xfinity Voice on this page for its online steps.
CallRail call tracking
- If your website or ads show a CallRail tracking number, set this up inside CallRail: its call flow already decides where those calls ring.
- Sign in to CallRail, select the Settings icon on the left, choose your company, select Workflow, and open the call flow your tracking numbers use.
- In its first Dial step keep your office number, pick how long it rings in the duration drop-down, and select the checkbox that prevents voicemails and automated systems from answering, so your office voicemail cannot take the call first.
- Select Dial again below that step and enter your OnCrew number as the destination for calls nobody answers. Leave that checkbox unchecked on this second step: Sarah is an automated system, and CallRail would stop her from answering. Select Save and assign the call flow to your tracking numbers.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah, make your OnCrew number the first Dial step's destination. CallRail recommends a few test calls from a phone that is not in the call flow.
ServiceTitan Phones Pro or Basic Phones
- Phones Pro runs on Dialpad. In Dialpad open Admin Settings, then Main Line (or the department that answers your calls), select Business Hours & Call Routing, and click Edit Call Routing.
- Under Fallback Options choose To a team member / room phone / external number, enter your OnCrew number, and press Enter to save. Calls your team does not answer then go to Sarah.
- Basic Phones only tracks calls: your ServiceTitan tracking numbers ring your forwarding number, so set up forwarding on that number with its phone carrier instead. Pick that carrier from the list on this page.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
ServiceTitan says the fallback setting needs the Phones Pro feature with the Dialpad integration.
VoIP phone services
Google Voice
- In the Google Voice app open Settings, then Calls. Under Making and receiving calls choose Use carrier only, so calls to your Google Voice number ring your cell through your carrier instead of inside the app.
- Still under Calls, turn Screen Calls off. With screening on, Google asks whoever answers to press 1 first, and your receptionist cannot press it.
- Under Incoming calls, make sure your cell is the linked number that rings (turn off any other devices you do not want ringing).
- Now forward the calls your cell does not answer to your OnCrew number: open your forwarding page, find your cell carrier under Cell phone carriers, and dial its no-answer code from your cell. Pick the shortest ring time your carrier allows so the call reaches Sarah before Google's own voicemail picks up.
- Tap Test it for me on your forwarding page: OnCrew rings your Google Voice number and checks that Sarah answers. If Google's voicemail answers instead, shorten the ring time on your cell carrier and test again.
If you would rather not route through your cell: put your OnCrew number on your website, Google listing and trucks and keep Google Voice for texting, or move your Google Voice number to OnCrew (Google charges $3 to unlock a number for porting, nothing if you originally ported it in; reply to any OnCrew email and we handle the port, usually one to three weeks, nothing changes until it completes). If your Google Voice is part of Google Workspace, Google's answer is its auto attendant; reply and we set that up with you. Do not add your OnCrew number as a linked number in Google Voice: Google verifies a linked number by calling it with a code that has to be typed in, and the receptionist cannot type it.
Sideline or Index (Pinger)
- Put your OnCrew number where new customers find you: your Google Business Profile, your website, your HomeAdvisor, Angi, Yelp and Facebook pages, and your truck. Sarah answers every call to it, and the number you have now keeps working for texts and for the customers who already have it.
- Or move the number itself to OnCrew so nothing changes for your customers. In Sideline open Settings, then Support (iPhone) or Get Help (Android), then Port-Out Number. Sideline charges a one-time $19.99 unlock unless you ported the number in, then gives you an account number and PIN. Reply to any OnCrew email with them and we handle the port; your number keeps working in the app until the port completes.
Sideline and Index cannot forward a call to another number (their own help pages say so), so no dial code or app setting will send your calls to Sarah, and a forwarding test will always show the call answered in the app. TextFree numbers are the same. To hear Sarah now, call your OnCrew number from any phone.
RingCentral
- In the RingCentral app click Settings, then Phone, then Incoming call rules. An admin can do the same in the Admin Portal for the extension your main number rings.
- Click Incoming calls (under Work hours or After hours if you use a schedule). In the If no one answers section choose Forward the call, enter your OnCrew number, and click Save.
- Under Ring settings, the dropdown next to each phone sets how long it rings before the call counts as missed, from 1 ring (5 seconds) to 15 rings (75 seconds). 3 or 4 rings lets you answer first and still gets callers to Sarah quickly.
- Under Welcome greeting, leave Ask me if I want to answer switched off. It makes whoever answers press 1 to accept the call, and Sarah cannot press it.
- Then tap Test it for me on your OnCrew forwarding page: OnCrew rings your business number and checks that Sarah answers.
To send every call to Sarah instead: click your profile picture, then Call rules, then Forward all calls. In the Incoming calls dropdown select Forward the call, click Number, enter your OnCrew number, and click Save.
Business phone system (Twilio, Bandwidth, Telnyx hosted)
Your number is hosted on a telephony platform, so forwarding is a setting inside the phone system built on it (Grasshopper, OpenPhone, Dialpad, a custom app, or similar), not a dial code. If yours is listed under Office phone systems, use those steps. Otherwise, in that system, set no-answer or overflow forwarding to your OnCrew number, and switch off any setting that asks whoever answers a forwarded call to press 1. If you are not sure which system it is, reply to any OnCrew email with the name of the app you answer calls in and we will send the exact steps.
Vonage
Every call: dial *72XXXXXXXXXX (turn it off with *73). From the handset: every call goes straight to OnCrew.
Sign in to your Vonage online account, open Features & Settings, then Calling Features, then Call Forwarding. Enter your OnCrew number and choose how many seconds your phone rings before forwarding. From the handset, *72 turns on forward-all (every call, not just missed ones) and *73 turns it off.
Confirm forwarding before you trust it
Run a quick set of test calls before you lean on the system. Two or three calls catch common setup issues before a real customer ever hears one.
Let OnCrew test the forwarding for you
On your forwarding page, tap Test it for me. OnCrew rings your business number from one of its own lines, lets it ring past the no-answer timer, and texts you whether the call reached your AI receptionist. No second phone needed, which matters when your cell is your business number.
Confirm the AI greets in your business name
Listen for your company name in the greeting. If the greeting is wrong, fix it in your OnCrew dashboard before forwarding stays on.
Run a routine call: a quote request
Pretend to be a homeowner asking for a basic quote. Confirm the AI captures name, callback number, address or service area, and the job description in plain language.
Run an urgent call in your trade
Try a no-heat call for HVAC, an active leak for plumbing, a sparking outlet for electrical, or a storm leak for roofing. Confirm the AI raises urgency and routes the message to your on-call contact.
Check the message in your dashboard and alerts
Open the call summary in OnCrew and confirm the transcript, caller details, and urgency level look right. Make sure the alert hit your configured alert channel for your team.
Adjust hours and routing, then test again
If anything is off, adjust forwarding hours, on-call contacts, or AI prompts in your OnCrew settings, then run one more test call before you lean on the system.
Forwarded calls, captured cleanly
When a forwarded call lands on OnCrew, the AI greets in your business name, asks the right questions for your trade, and writes everything up so your team can call back fast.

How forwarding lands by trade
Forwarding modes look the same on a carrier portal. The calls you cannot afford to miss do not. Each trade guide below covers urgency rules, on-call alerts, and the call types worth forwarding for that trade.
HVAC
Most HVAC shops keep daytime calls live and forward nights, weekends, and the no-heat or no-cool spikes that rip through January and July. Los Angeles HVAC shops can use the LA HVAC answering service page for heat-wave forwarding, neighborhood routing, and after-hours intake context.
Plumbing
Burst pipes, sewage backups, and water heater failures do not wait for office hours. Plumbing shops typically forward overflow during the day and forward-all on nights and weekends so an active leak does not roll to voicemail. Los Angeles plumbing shops can use the LA plumbing AI answering page for Hollywood overflow, hillside access notes, and after-hours active-leak intake context.
Electrical
Sparking outlets, panel failures, and outage calls need the right safety questions before a field decision is made. Electrical shops use forwarding so the AI captures symptoms and routes urgent calls to the on-call electrician with full context.

Storm leaks and emergency tarp requests come in waves. Roofers forward the line during storm windows so the AI captures the roof type, the leak location, and access details for the crew that is actually on rotation.

Call forwarding FAQ
Quick answers for contractors evaluating forwarding their existing number to an AI receptionist.
How do I set up emergency call routing for a contractor business?
To set up emergency call routing for a contractor business: (1) forward your business number to a 24/7 AI receptionist or trained dispatcher; (2) configure trade-specific triage questions for your top emergencies (HVAC: gas smell, no heat; plumbing: burst pipe, sewer backup; electrical: panel down, sparking); (3) set urgency thresholds that trigger an immediate email to the on-call tech with full job context. OnCrew automates all three with a 14-day free trial at $49/month.
Do I keep my existing business number when I forward calls to OnCrew?
Yes. Call forwarding sends your existing business number to OnCrew without moving or porting the number. You keep the same number on your trucks, signs, Google Business Profile, and ads. OnCrew gives you a forwarding target, and you configure forwarding from the carrier or phone system that hosts your line.
Should I forward all calls or only after-hours and overflow?
It depends on who answers the phone today. If you are solo or do not have a dedicated phone person, forward-all is usually simplest because forwarded calls are answered in your business voice. If you already have a daytime office, forwarding only after-hours and weekends keeps the daytime experience the same and adds clean nights and weekends coverage. If you only want to catch missed calls, forward on busy or no-answer so OnCrew picks up only when a real person did not.
Does OnCrew set up call forwarding on my carrier for me?
The change is configured by you on your carrier or phone system: OnCrew does not control your carrier account, and forwarding leaves your number where it is. Most contractors finish forwarding by following the steps for their carrier. Rather do it on the phone? Call (818) 578-4783: Sarah can start your line on the call and read you the code to dial.
What does OnCrew capture when a forwarded call comes in?
OnCrew greets the caller in your business name, asks the right questions for your trade, and captures the caller's name and callback number, service address or service area, plain-language description of the job, urgency level, whether they are a new or existing customer, and a preferred callback window. You get a full transcript, the call audio, and a team alert on your configured alert channel for urgent jobs.
How much does it cost once my number is forwarded to OnCrew?
Plans are Starter at $49 per month with 100 included calls, Pro at $149 per month with 400 included calls, and Multi-Truck at $349 per month with 1,000 included calls. Calls beyond your plan are $0.99 each. Every plan includes a 14-day free trial so you can test forwarding on a real number before you commit.
What happens if I want to turn forwarding off and answer the calls myself?
Call forwarding is a setting on your existing line. You can turn it off in your carrier portal or with a standard handset code at any time and your number will ring as it did before. Many contractors leave forwarding on after hours and weekends and answer their daytime calls live.
