Human Add AI

What kind of business number do I have?

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.

Before you can forward calls, you need to know what kind of phone service you're on. The method is different for each. Here's how to tell in under a minute.

The three types in plain English

Wireless (cell)

Runs over a mobile network. You carry the phone. The bill comes from Verizon, AT&T, T-Mobile, or a carrier that resells their network (Spectrum Mobile, Cricket, Metro, Mint, Google Fi, Visible, etc.).

Forwarding method: star codes dialed from the phone, or sometimes the carrier's app.

Landline

The old-school kind - copper wire running into your building, analog dial tone. Increasingly rare; most "landlines" today are actually VoIP dressed up in traditional wiring.

Forwarding method: star codes dialed from the handset (*72 / *73). May require a small monthly add-on depending on your carrier.

VoIP (Voice over Internet Protocol)

Runs over the internet. Can look like a desk phone, an app, or even a traditional-looking landline - but the audio travels over your internet connection, not a phone line. Everything from RingCentral to Google Voice to Comcast Business Voice is VoIP.

Forwarding method: web portal or app. Some VoIP services also support star codes from the handset.

How to tell which one you have

The fastest test: who sends your bill?

Look at the provider on your monthly bill (or auto-charged credit card statement). Match it below:

The phone itself gives hints

If you still can't tell

Call the number from a cell phone and listen for clues on the greeting / hold music / voicemail. If you hear "you have reached [carrier] voicemail," that's a strong signal. If you have to ask IT or a previous business owner - do that, it's the fastest path.

Or: call us at (617) 812-5251 and tell us what you have. We'll point you to the right guide.

"Business number" can mean two things

One common source of confusion: people sometimes mean "the number customers call" (could be any type), and sometimes mean "the landline that the phone company installed when we opened in 1982." These are often different numbers! Older businesses often have a landline that forwards to a newer VoIP line, which a manager then forwards to their cell.

If your business number is the result of multiple layers of forwarding already, pick the outermost one - the number customers actually dial - and change the forward there. Replacing a deep-layer forward won't help if the layer above it is still pointing at the wrong place.

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 →

What changes after the first month on the platform

After thirty days on Human Add AI, three things have changed for the typical operator. First, the recovered-revenue math has compounded into a concrete dollar number that the operator can see in the dashboard and in the bank account. For most single-location service businesses, the first-month recovered revenue lands between $6,000 and $25,000, against a $497 to $997 plan cost. The platform has paid for itself many times over, and the operator mental model has shifted from "evaluating a new vendor" to "operating a critical revenue tool".

Second, the agent has been tuned to the specific cadence of the business. Tuning continues forever (every business evolves, every season brings new call patterns, every new service line needs new intake questions), but the bulk of the agent customization is done in the first 30 days. After that, the operator can edit the knowledge base from the dashboard for most changes and only needs to ping the Human Add AI team for the larger script revisions.

Third, the operator has started thinking about the second-order use cases the platform unlocks. Outbound missed-call callback usually goes live in month two for operators on Professional or Enterprise. Appointment reminder calls usually go live in month three. By month four, the platform is doing both inbound and outbound work that previously required either a part-time staffer or a separate scheduling service, and the operator is running a tighter business with the same overhead.

What the platform does not try to do

Being clear about scope matters because every platform has things it intentionally does not do, and the operator should know those up front. Human Add AI does not try to be a unified CRM. It integrates with the CRM the operator already uses (Jobber, Housecall Pro, ServiceTitan, Salesforce, HubSpot, Clio, Dentrix, twenty more) but does not try to replace it. The platform sends the right data into the right system; it does not try to be the system of record.

It also does not try to be a marketing automation tool. There is no email sequence builder, no landing-page builder, no funnel analytics dashboard. The platform handles the phone (inbound and outbound calls plus SMS lead alerts) and stops there. Operators who want marketing automation use a dedicated tool for that and integrate the two via webhook.

It does not try to be a workforce management platform. There is no shift scheduling, no time tracking, no payroll integration. The platform delivers leads to the operator and the operator dispatches them through whatever workforce tools they already use. The narrow scope is intentional: Human Add AI is built to be the best at one specific job, not adequate at five jobs.
