How to Set Up Call Forwarding to an AI Receptionist

Setting up call forwarding is the technical step that connects your existing business number to your AI receptionist. It's not complicated, but the details matter — pick the wrong forwarding mode and you'll either forward calls you wanted to take yourself, or miss the ones you meant to send. This guide walks through the options and the steps.

The three ways to connect your number

1. Conditional forwarding (recommended to start)

Conditional forwarding — sometimes called "forward on no answer" or "forward on busy" — sends a call to your AI receptionist only when you don't pick up within a few rings. You keep your number, you can still answer when you're free, and anything you miss gets captured by the AI instead of going to voicemail. This is the best way to start because it's reversible and low-risk: if you don't like the AI, you just turn off forwarding and your calls ring normally again.

2. Unconditional forwarding

Unconditional forwarding sends every call straight to the AI receptionist without your phone ringing at all. This makes sense once you've tested the AI and you want it to handle everything, including calls you would have answered yourself. It gives the most consistent caller experience — every caller gets the same instant answer — but it means you're choosing not to answer directly anymore.

3. Porting your number

Porting moves your existing number to your AI receptionist provider so the number lives with them. Every call goes through the AI, and you don't need forwarding at all. Porting is permanent (though you can port back out later), takes longer because it depends on your current carrier, and means you can't easily fall back to your old setup. Most businesses start with forwarding and only port later if they want to simplify.

How to set up conditional forwarding

The exact codes and menus depend on your phone provider, but the steps are the same everywhere:

1. 1Ask your AI receptionist provider for the forwarding number they assigned you.
2. 2Get your business phone number's conditional-forwarding feature turned on. Most mobile and VoIP providers let you set this in their app or with a star code (for example, *73 or *71 on many US mobile carriers — check your provider's support page).
3. 3Set the ring time before forwarding. Aim for about 15–20 seconds (roughly 3–4 rings) so you get a chance to answer first.
4. 4Enter the AI provider's forwarding number as the destination.
5. 5Test it: call your business number from another phone and don't answer. Confirm the AI picks up and the call flows through correctly.

If your phone is a landline or office system, your provider's support line can walk you through the exact menu. If you use a VoIP service like a cloud phone system, forwarding is usually a toggle in the dashboard.

What to test before you go live

Before you rely on forwarding for real customer calls, run through a quick checklist:

• Call your business number and don't answer — confirm the AI picks up within a few rings.
• Call and answer yourself — confirm conditional forwarding does NOT send it to the AI when you pick up.
• Make sure your voicemail is turned off or set to answer after more rings than your forwarding, so the AI gets the call instead of your voicemail box.
• Confirm the AI captures your test caller's name and number and that you receive the alert text and email.
• Test an "emergency" scenario from your rules to confirm it transfers live to your phone.

Don't skip carrier registration

There's one step that has nothing to do with forwarding but everything to do with going live: your AI receptionist's phone number must be registered with carriers for business texting and calling. This is a legal requirement, not a provider choice, and it takes a few business days. Your AI receptionist provider handles the registration, but they need accurate business information from you to do it. Until registration is complete, the number can't send texts or make calls reliably, so plan the timeline around it.

Switching modes later

One of the nice things about starting with conditional forwarding is that you can change your mind. If you find you'd rather have the AI answer everything, switch to unconditional forwarding. If you want to take calls yourself for a while, turn forwarding off. Porting is the one move that's harder to reverse, so save it for when you're sure.
