Human Add AI help center covers call forwarding setup for every major US carrier (Verizon, AT and T, T-Mobile, Spectrum, Comcast, RingCentral, Google Voice, OpenPhone, and twelve more), PWA install instructions for the mobile dashboard, knowledge base editing, and account management. Most setup guides take under five minutes to complete.
OpenPhone uses a "Ring Order" to decide who rings when a call comes in - team members, and/or external forwarding numbers. This guide shows you how to add one.
The quick version
Open the OpenPhone app (desktop or mobile), go to Settings → your number → Ring Order, and add the destination as an external forwarding number.
Step-by-step: set up call forwarding in OpenPhone
1
Open the OpenPhone app on desktop or mobile, or sign in at my.openphone.com.
2
Click Settings, then select the phone number you want to forward. OpenPhone accounts often have multiple numbers - pick the right one.
3
Go to the Ring Order tab (on some plans this is called "Inbound calls").
4
Enable Forward calls to external numbers. Enter the destination number. You can choose "ring only this number" for a clean forward, or "ring in sequence" if you want OpenPhone to try your app first and fall through to the destination.
5
Save. Changes apply within about a minute.
6
Test by calling your OpenPhone number from another phone.
Alternative: Business-hours forwarding
OpenPhone lets you set different call-handling rules for business hours vs. after-hours under Settings → your number → Business hours. Forward only after-hours calls to your AI while you take daytime calls yourself.
Things worth knowing
OpenPhone doesn't charge extra for forwarding to external numbers, but forwarded minutes count against your plan's outbound allowance.
If you have team members on a shared OpenPhone number, each of them can be in the Ring Order - add the external forward at the end so team members try first, AI picks up if nobody answers.
OpenPhone's integration with most CRMs logs forwarded calls automatically, so your records stay clean even when the AI answers.
Forwarding to an AI receptionist?
The whole reason you're reading this is probably to stop missing calls. If you're setting up call forwarding to send calls to a voice assistant, an answering service, or an AI, the steps above are the same - you just enter their number as the forward-to destination. Human Add AI gives you a dedicated AI receptionist that answers 24/7, captures every caller's intent, and texts you the details. Try it free for 7 days →
Troubleshooting
Calls still ring the old way. Most VoIP systems take 30 - 60 seconds to apply forwarding changes. Wait and test again. If it still doesn't work, sign out and back in, or restart the desk phone.
You saved the rule but don't see it. OpenPhone usually applies rules to one specific number or extension. Make sure you're editing the right one - business accounts often have multiple numbers on the same login.
Callers hear "number not in service." Double-check the destination number you entered. OpenPhone often requires the full 10-digit US format, sometimes with a +1 prefix.
You want some calls to stop forwarding. Most OpenPhone plans support conditional rules (forward only after X rings, forward only from Y caller ID, etc.). Look for "Advanced" or "Rules" in the forwarding settings.
Every Human Add AI trial gives you a dedicated local phone number with a fully custom AI receptionist on the other end. Free for 7 days, $10 refundable activation.
Human Add AI runs three flat monthly plans with no setup fees and no annual contracts. The Starter plan at $497 per month covers up to 250 answered calls, single-location service, and the core conversation engine that books appointments and qualifies leads. Most single-truck operators, solo practitioners, and one-shop businesses fit comfortably inside Starter for the first six to twelve months.
The Professional plan at $997 per month covers up to 750 answered calls, multi-location routing, real-time CRM sync into Jobber, Housecall Pro, ServiceTitan, Clio, Lawmatics, Dentrix, Open Dental, and twenty other systems, and after-hours emergency escalation rules. This is the most common plan once a business clears about a hundred answered calls per week.
The Enterprise plan at $1,997 per month covers unlimited inbound calls, dedicated agent tuning, white-label phone numbers, and direct routing to your on-call dispatcher. Enterprise also unlocks outbound calling for missed-call callbacks, lead nurturing, and appointment reminders, billed at $0.14 per outbound minute.
Every plan includes the same conversation quality, the same booking and CRM functionality, and the same 24/7 uptime. The differences are call volume, location count, and outbound capability. No plan has hidden seat fees, per-minute inbound charges, or transcript fees. The first call you take pays for itself in most service businesses, and the platform breaks even for the average operator inside the first three weeks.
Frequently asked questions
How fast does the AI answer the phone?
Every inbound call is answered inside two rings. The agent picks up before voicemail ever triggers, which means a service business never loses a lead to "they did not pick up, so I called the next listing." The two-ring pickup is hard-coded into the platform and is the same on Starter, Professional, and Enterprise plans.
What happens if the AI cannot answer a question?
The agent is built with explicit fallback rules. If a caller asks something outside the trained scope (a complicated insurance question, an unusual scheduling request, a pricing question for a service the business does not offer), the agent says so plainly and offers to text a member of the team with the caller's number. The text arrives on the on-call phone within seconds, with the caller's name, number, and a summary of what they wanted.
Can the AI book appointments directly on my calendar?
Yes. The agent reads the live availability on your Cal.com, Google Calendar, Calendly, Acuity, Jobber, Housecall Pro, ServiceTitan, or other booking system and offers the caller real slots. When the caller accepts a slot, the agent confirms the address or the service location, sends a confirmation text to the caller, drops the appointment onto your calendar with all the intake details in the notes field, and texts you the booking summary.
Does the AI work after hours and on weekends?
Yes. Human Add AI runs 24/7/365 by default. The agent answers every call regardless of time, qualifies the lead with the same questions a daytime receptionist would ask, and either books an appointment on the next available business-day slot or texts your on-call dispatcher if the call qualifies as an emergency. Roughly 35 percent of service-business calls happen outside Monday-to-Friday 9-to-5, and most of those are still booking-quality leads.
What CRMs and booking systems does it integrate with?
The platform integrates natively with Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, RazorSync, Cal.com, Google Calendar, Calendly, Acuity Scheduling, HubSpot, Salesforce, Pipedrive, Zoho CRM, Clio, Lawmatics, Lawyaw, MyCase, Practice Panther, Dentrix, Open Dental, Eaglesoft, Curve Dental, ServiceM8, and twenty other vertical-specific systems. If your CRM is not on that list, the team will build a Zapier or webhook handoff during onboarding.
Is Human Add AI HIPAA compliant for medical and dental practices?
Yes. Human Add AI signs a Business Associate Agreement on the Enterprise plan and routes all medical and dental conversations through a HIPAA-compliant pipeline with encryption in transit, encryption at rest, audit logging, and seven-year retention controls. The standard intake questions for medical and dental practices avoid collecting protected health information on the phone and route triage decisions to the on-call clinician.
What happens if I want to cancel?
Plans are month-to-month with no contract. Cancel anytime through the dashboard or by emailing info@humanaddai.com. Your forwarding number stays active through the end of the billing cycle, the dashboard exports every call recording and transcript as CSV plus MP3, and there is no off-boarding fee. Most operators do not cancel because the platform pays for itself in recovered missed-call revenue, but the option is always one click away.
How is this different from a virtual receptionist service?
Human virtual receptionist services like Smith.ai and Ruby Receptionists charge per minute or per call, which means costs scale with success. A busy week can cost more than the entire Human Add AI monthly plan. Human virtual receptionists also have a small staff pool, so callers reach a different person every time, and the receptionist does not know your vertical. The Human Add AI agent is custom-built for your business, costs the same flat price no matter how many calls come in, and answers every call the same way with the same accuracy.
How the platform fits into the daily operations rhythm
Once Human Add AI is live, the daily operations rhythm for a service-business owner changes in a small number of concrete ways. The phone stops being something the owner thinks about during business hours. Voicemail goes away because every call gets answered live. The booking calendar fills with new appointments without anybody manually keying them in. SMS alerts arrive on the on-call dispatcher's phone for every qualified lead, with the caller name, number, and intake summary already attached.
The weekly summary email arrives every Monday morning with the call count, the booking count, the SMS lead count, and the recovered-revenue math. Most operators stop opening the daily call list after the first month because the system has earned trust at that point and the weekly summary is enough. The dashboard remains available for the rare investigation: an operator drilling into a specific booking, a customer calling back about a previous conversation, or a tuning request to refine the agent script.
The change in the operator own time is the second-order effect that most operators report as the biggest unexpected value. Sixty to ninety minutes per day of phone qualification time gets returned to the operator, which can be spent on revenue-generating work, on team management, or on actually taking a lunch break. The dollar value of that time alone usually exceeds the platform monthly price for any owner-operator profile.
What the platform looks like a year in
The shape of Human Add AI on month twelve looks different from month one in a few specific ways. The agent has been tuned through dozens of small adjustments, each one shaped by a real call that was almost-perfect-but-not-quite. The CRM integration has been used long enough that the operator has cleaned up the data flow on their end, which means the lead summaries are landing in the right pipeline with the right tags. The outbound module (if enabled) has settled into a daily cadence that the operator runs without thinking about it.
The recovered-revenue number has also gone from a launch-week curiosity to a baseline expectation. Most operators stop tracking it as a single metric and start treating it as part of normal revenue. The platform shows up as a $497 to $1,997 line item in the monthly operating budget and quietly returns 10 to 30 times that in recovered bookings, the same way a good lead-acquisition channel does.
The one thing that almost never changes is the support cadence. The Human Add AI team continues to answer questions inside the SLA, continues to push tuning updates when the operator asks, and continues to send the weekly summary email every Monday. The platform is built to be set-it-and-forget-it, but the team is built to be available the moment the operator needs them.
How operators run the platform after the first quarter
Quarter-two on Human Add AI is when the platform fades into the background of how the business runs. Operators stop logging into the dashboard daily and start treating it like the rest of the operational infrastructure: a tool that does its job, gets checked weekly, and only surfaces when something needs adjusting. The weekly summary email becomes the primary touchpoint, and the dashboard becomes a reference point for the occasional investigation.
By quarter-three, most operators have layered in the outbound use cases that the platform unlocks. Missed-call callback runs automatically, appointment reminders go out 24 hours before booked time, and post-service review-collection calls go out the next business day after a completed job. Each of these adds a small amount of outbound usage to the monthly bill (typically $30 to $90) and returns a much larger amount in recovered customers, kept bookings, and earned Google reviews.
By quarter-four, the platform is one of the cheapest operational line items in the business and one of the highest-leverage. Operators who have made it this far on the platform almost never cancel, because the alternative (going back to voicemail or paying for a virtual receptionist) is plainly worse on cost, coverage, and quality.
