How to Set Up Call Forwarding on Your Business Phone (2-Minute Guide)

Why Call Forwarding Is the Most Important 2 Minutes You'll Spend This Week

Every business owner knows the problem. You're on a job, in a meeting, or helping a customer face-to-face, and the phone rings. You can't answer. The caller hangs up. Another potential customer gone.

Call forwarding is the fix, and it takes less than 2 minutes to set up on any American carrier. Once active, unanswered calls route to a second number automatically. That number can be a colleague, an answering service, or an AI receptionist like CallCatch that texts back within 30 seconds.

The best part is that you don't need any technical knowledge. You don't need to call your carrier. You don't even need to log into anything. A simple dial code from your phone activates it instantly.

If you're already paying for an AI receptionist or missed call tool and haven't set up forwarding yet, you're leaving money on the table. This guide gives you the exact steps for every major American carrier.

AT&T Call Forwarding (Cell Phone and Landline)

AT&T is one of America's largest carriers, and their call forwarding setup is straightforward.

AT&T Cell Phone - Immediate forwarding (all calls): - Activate: Dial *21*[forwarding number]# then press call - Deactivate: Dial ##21# then press call

AT&T Cell Phone - Forward on no answer (recommended for CallCatch): - Activate: Dial *61*[forwarding number]# then press call - Deactivate: Dial ##61# then press call

AT&T Cell Phone - Forward when busy: - Activate: Dial *67*[forwarding number]# then press call - Deactivate: Dial ##67# then press call

AT&T Landline: - Activate: Pick up the handset, dial *72, then the forwarding number. Wait for a confirmation tone or the forwarded phone to ring - Deactivate: Pick up the handset, dial *73

For most business owners, "forward on no answer" is the right choice. This means calls ring your phone first. If you don't pick up within 15-30 seconds, the call forwards to your AI receptionist or backup number. You still answer when you can, but you never let a missed call go unanswered when you can't.

Pro tip: After activating, call your own number from another phone to test that it's working. You should hear it ring, then forward after a few rings.

Verizon Call Forwarding (Cell Phone and Landline)

Verizon is the largest carrier in the US, and their forwarding setup depends on whether you're on a cell phone or landline.

Verizon Cell Phone - Immediate forwarding: - Activate: Dial *72 then the forwarding number, then press call - Deactivate: Dial *73 then press call

Verizon Cell Phone - Forward on no answer: - Activate: Dial *71 then the forwarding number, then press call - Deactivate: Dial *73 then press call

Verizon Landline: - Activate: Dial *72, wait for dial tone, then dial the forwarding number. Wait for two beeps confirming activation - Deactivate: Dial *73 and wait for two beeps

Verizon Business customers can also manage forwarding through the My Business portal or the Verizon Business app, which gives you more control over forwarding schedules and rules.

One important note: Verizon uses slightly different codes than AT&T and T-Mobile. The *72/*73 codes are Verizon-specific. If you switch carriers, you'll need to update your forwarding setup with the new carrier's codes.

For Verizon Business Digital Voice customers, log into the admin portal at voiceedge.verizon.com to set up advanced forwarding rules including time-based routing.

T-Mobile and VoIP Systems (RingCentral, Grasshopper, Teams)

T-Mobile Cell Phone: - Immediate forwarding: Dial **21*[forwarding number]# then press call - Forward on no answer: Dial **61*[forwarding number]# then press call - Forward when busy: Dial **67*[forwarding number]# then press call - Cancel all forwarding: Dial ##002# then press call

T-Mobile also lets you manage forwarding through the T-Mobile app under Settings and Call Forwarding.

VoIP Systems (increasingly common for American businesses):

RingCentral: Go to Settings, then Call Handling and Forwarding. Add a forwarding number under "When I don't answer." Set the ring duration before forwarding (15-20 seconds recommended).

Grasshopper: Log into your account. Go to Extensions, then Call Forwarding. Add your CallCatch number as a forwarding destination.

Microsoft Teams Phone: In the Teams app, click Settings, then Calls. Under "Call answering rules," select "Forward my calls" or "If unanswered" and enter your forwarding number.

Google Voice: Go to Settings, then Calls. Select "Forward calls to linked numbers" and add your forwarding destination.

Most VoIP systems also allow forwarding rules based on time of day, which is useful if you want calls to forward to your AI receptionist only after business hours.

Best Practices: Getting the Most Out of Call Forwarding

Setting up forwarding takes 2 minutes. Getting the most out of it requires a few smart decisions.

Use "forward on no answer" instead of immediate forwarding. This lets you answer calls when you're free, but catches everything you miss. Most carriers let the phone ring 4-6 times (about 15-25 seconds) before forwarding.

Always test after setup. Call your business number from a different phone. Let it ring without answering. Confirm it forwards correctly and that your AI receptionist or backup number receives the call.

Forward to an AI tool, not just another phone. Forwarding to a second cell phone just moves the problem. You need something that will always answer. AI text-back tools like CallCatch respond to every forwarded call within 30 seconds, 24/7.

Set up after-hours forwarding separately if your VoIP system supports it. During business hours, use "forward on no answer." After hours, use immediate forwarding so every call goes straight to your AI receptionist without ringing an empty office.

Keep your forwarding number saved somewhere accessible. If you ever need to change carriers or update your setup, having the forwarding number handy saves time. CallCatch provides your dedicated forwarding number in your dashboard.
