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.
RingCentral gives you more forwarding control than almost any other phone system - rules by time, caller, or area code. The basic setup takes under 2 minutes.
The quick version
Sign in to your RingCentral account at service.ringcentral.com, find the number or user you want to forward, open Call Handling & Forwarding, and add a new forwarding destination.
Step-by-step: set up call forwarding in RingCentral
1
Sign in to the RingCentral web portal at service.ringcentral.com. Admin access is required to edit other users; user-level access is enough to forward your own extension.
2
For a user's calls: go to Settings → Phone → Call Handling & Forwarding. For a main company number: go to Phone System → Phone Numbers → pick the number → Call Handling.
3
Click Add Number or Add Ring and paste in the destination number you want calls forwarded to. RingCentral calls these "Ring Phones" or "Forward Numbers."
4
Set the ring order. Choose whether RingCentral should try the destination first (skip your desk phone entirely) or ring your desk phone first and forward only on no-answer. For an AI receptionist, "Forward Immediately" is usually what you want.
5
Save the change. It applies within about 30 seconds - no restart needed.
6
Test by calling your RingCentral number from a different phone. It should ring at the forwarding destination.
Alternative: RingCentral mobile app
From the RingCentral app: tap the menu → Settings → Phone → Call forwarding. Toggle on and pick the destination. Changes sync across devices.
Things worth knowing
RingCentral's "Rules" feature lets you set forwarding by time of day, caller ID, or area code. Useful if you only want after-hours calls to go to your AI.
You can forward per-user or per-number. Per-number forwarding is what you usually want for a main business line.
RingCentral doesn't charge extra for forwarding to external numbers, but forwarded calls count against your plan's outbound minutes.
If you use the RingCentral desktop app (RingCentral Phone or the unified Glip/Video/Phone app), forwarding rules are controlled from the same web portal - the app just follows whatever the portal says.
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. RingCentral 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. RingCentral often requires the full 10-digit US format, sometimes with a +1 prefix.
You want some calls to stop forwarding. Most RingCentral 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.

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.
The honest evaluation timeline
The honest evaluation timeline for an operator deciding whether to install Human Add AI looks something like this. Day zero: call the demo line at (617) 812-5251 from any phone and run a real scenario. The demo takes about ninety seconds and gives a faithful preview of conversation quality. If the conversation quality passes the bar, proceed. If it does not, the operator has saved themselves the rest of the evaluation. Day one: fill out the ten-minute onboarding form. This creates a custom test agent for the specific business, which is free to use during evaluation.
Day two: the Human Add AI team builds the test agent and ships back recorded test calls. The operator listens to the samples, requests any adjustments, and decides whether to proceed. Day three: the operator forwards a test line (a Google Voice number, a secondary business line, or a fresh Twilio number) to the agent and runs a week of real test calls. Day ten: review the test-week data in the dashboard, compare recovered-revenue against the plan price, and decide whether to forward the real business line.
For operators who already know they have a missed-call problem, the evaluation usually collapses into a much shorter window: call the demo, fill the onboarding form, hear the recorded samples, forward the business line. Most operators who go this path are live and recovering missed-call revenue inside 72 hours of first hearing the demo.
