How call forwarding works

Keep your number where it is. Set up in about a minute on most carriers. Reversible any time.

Last updated May 3, 2026

Call forwarding is the simplest way to use your existing business number with EMOR's AI receptionist. Your number stays right where it is — at Verizon, AT&T, T-Mobile, your VoIP provider, wherever — and you tell that carrier to redirect incoming calls to a number EMOR gives you.

On most carriers the whole setup takes about a minute (a few minutes if your carrier uses a web portal instead of a dial code), and you can turn it off any time by dialing three digits or toggling a setting back off.

The mental model

Think of forwarding as “automatic redirect” at the carrier level. When someone calls your published business number, your carrier intercepts the call before it rings your phone, and instead routes it over to a different number — the EMOR number we set up for you. From there, our AI receptionist answers and handles the call.

The caller has no idea any of this happened. They dial the same number that's on your flyers and your Google listing, and the call sounds exactly like a normal call. They don't see the EMOR number. Behind the scenes, it's just a different system picking up.

What happens during a call

  1. A new customer dials your published number — say (555) 123-4567.
  2. Your carrier (Verizon, AT&T, etc.) sees the call coming in.
  3. Because forwarding is enabled, your carrier redirects the call to the EMOR number — say (555) 987-6543 — instead of ringing your phone.
  4. EMOR's AI receptionist picks up and handles the conversation: answering questions, capturing leads, booking appointments.
  5. When the call ends, you see it in your dashboard like any other call.

Setup at your carrier

Forwarding is enabled at your carrier — not in the EMOR dashboard. Most landline and VoIP carriers support a universal *72 dial code: pick up your business phone, dial *72followed by the EMOR number we set up for you, then press call. You'll hear a confirmation tone — typically a short beep or a brief recording, depending on the carrier. Hang up. Forwarding is now active.

AT&T and T-Mobile wireless use a different code: **21* followed by the EMOR number, then #. Modern Verizon Wireless is also an exception — *72doesn't always take on LTE/5G plans; the My Verizon app is more reliable. Your carrier-specific guide (below) lists the right method.

Heads up: if your “business phone” is a desk extension behind a VoIP phone system (RingCentral, Vonage, an on-premise PBX, etc.), dial codes typed on the handset go to your phone system, not your carrier. Use your phone system's admin portal to set forwarding instead.

Some carriers (Vonage, RingCentral, 8x8, and others) handle forwarding through their app or web admin instead. EMOR shows you the exact steps for your specific carrier on the setup screen — pick one of these guides for the carrier-specific instructions:

The SMS trade-off — calls and texts use two numbers

Here's the one thing to understand about forwarding: voice calls forward, text messages don't. That doesn't turn SMS off — it means your calls and your texts come in on two different numbers.

  • Your published number takes calls. Customers dial it, your carrier forwards to EMOR, and the AI answers.
  • The EMOR number takes texts. EMOR provisions a dedicated number that handles SMS in full — booking confirmations, reminders, and AI text replies all send from it, under your own registered business sender.

The real trade-off is the split itself. A customer who texts your published numberreaches your personal phone, not the AI — carriers don't forward texts. So the EMOR number needs to be promoted as your text line: “Text us at …” on your website, signage, and email signature. EMOR shows you copy-ready lines for exactly this right after setup.

Want a single number for both? Portingmoves your number to EMOR so voice and SMS both run on the one number your customers already know — that's coming soon. For now, forwarding is the way to go live.

Verifying forwarding is working

After you set up forwarding at your carrier, EMOR will offer to place a test call to your published number. If forwarding is configured correctly, the test call routes through your carrier to EMOR within a few seconds — and your dashboard flips to “Forwarding confirmed.”

If the test call doesn't come through within 60 seconds, the most common causes are:

  • The forwarding code didn't take — try again, listening for the confirmation tone.
  • Your phone was off or out of service during the test.
  • Your carrier needs a minute to apply the change. Wait 30–60 seconds and retry.
  • Your business phone is an extension behind a VoIP phone system or PBX — the code went to the phone system, not your carrier. Set forwarding in the phone system's admin portal instead.
  • You're on modern Verizon Wireless and dialed *72 — try the My Verizon app instead.

Turning forwarding off

Forwarding is completely reversible. To turn it off, dial *73from your business phone (or toggle it off in your carrier's app). Calls go back to ringing your phone the way they used to, usually within a minute.

Some carriers use different deactivation codes — AT&T and T-Mobile use ##21#, for example. Your carrier- specific guide above lists the right code.

Cost considerations

With forwarding, you keep paying your existing carrier for the line, AND you pay for EMOR. Two bills. For most small businesses this is a few extra dollars a month and worth it for the flexibility — but it's why most customers eventually port their number after a month or two of forwarding-based trial.

If you're on a minute-capped mobile plan (not unlimited), some carriers count forwarded minutes against your monthly minutes — Verizon and AT&T both treat them as outbound calls. Most modern unlimited plans aren't affected.

Can I forward only when I don't answer?

Not via carrier forwarding — v1 forwards every call to EMOR. If you want a “ring my cell first, AI picks up when I miss it” pattern, that lives inside EMOR, not at your carrier: port your number to EMOR, then configure a ring-team-first rule in Receptionist → Routing so your line rings for a few seconds before the AI takes over. Carrier-side conditional forwarding (busy / no-answer only) isn't supported in v1.
