Busy Call Forwarding ATT: Codes, Setup, and What It Does

Busy call forwarding is a conditional forwarding feature. Unlike all-call forwarding, which sends every incoming call somewhere else, busy forwarding only kicks in when your line is occupied. If you are free, calls ring at your normal phone as usual.

This matters for a one-person business. If you are on a call with a customer and a second caller dials in, busy forwarding sends that second caller to the number you picked instead of a busy tone. You keep your public business number, and callers never know anything changed.

Busy forwarding is one of several conditional options. Others include no-answer forwarding, which activates after a set number of rings, and unreachable forwarding for when a phone is off or out of service. You can combine them so different situations route to different places.

• Conditional forwarding activates only in a specific situation, such as a busy line
• All-call forwarding sends every call to the destination, active or not
• Busy forwarding keeps your normal ringing when the line is free
• You choose the destination number when you activate the feature

AT&T Phone for Business uses star codes dialed from your business line. To forward calls when the line is busy, lift the handset and dial *90, then the 10-digit destination number, then #. To turn busy forwarding off, dial *91#.

The same product uses *92 plus the destination and # for no-answer forwarding, turned off with *93#. All-call forwarding is *72 plus the destination and #, turned off with *73#. If you have stored forwarding numbers in your online account, you may not need to reenter them when activating.

These codes apply only to AT&T Phone for Business. They do not work on AT&T wireless service or on AT&T Collaborate, which uses a different set of codes. Check your bill or account page for the exact product name first.

• Busy forwarding on: *90, destination number, #
• Busy forwarding off: *91#
• No-answer forwarding on: *92, destination, #; off: *93#
• All-call forwarding on: *72, destination, #; off: *73#

AT&T Collaborate is a hosted business phone system, and its feature access codes are different. In the official Collaborate feature access code guide, busy forwarding is activated by dialing *62 followed by the destination number, and deactivated with *63.

Collaborate also uses *92 plus the destination for no-answer forwarding (off with *93#) and *72 plus the destination for always forwarding (off with *73#). Note that these overlap with Phone for Business codes for some features but not for busy forwarding, which is why identifying your product matters so much.

On Collaborate, an administrator controls which feature access codes are available to each user. If *62 does not work from your extension, ask whoever manages your Collaborate account whether busy forwarding is enabled for your line.

• Busy forwarding on: *62 plus destination; off: *63
• No-answer forwarding on: *92 plus destination; off: *93#
• Always forwarding on: *72 plus destination; off: *73#
• An administrator may need to enable the feature for your extension

AT&T wireless lines use a different pattern. For busy forwarding on an AT&T cell line, dial *67*, then the 10-digit destination, then #, and wait for confirmation. To turn it off, dial ##67#. The related wireless codes are *61* for no-answer forwarding (##61# to disable) and *62* for unreachable forwarding (##62# to disable).

These codes are documented by Google for setting up conditional forwarding on AT&T cell lines, and they follow the standard GSM pattern used across carriers. Setup must be done from the phone itself. Forwarding applies to calls, not texts.

If your business line is an AT&T wireless line rather than a landline or hosted product, use these wireless codes and skip the *90/*91 instructions above. Dialing a landline code on a cell line will simply fail or do nothing.

• Busy forwarding on wireless: *67*, destination, #
• Disable with ##67#
• No-answer: *61*, destination, # (off: ##61#)
• Unreachable: *62*, destination, # (off: ##62#)

After activating busy forwarding, test it. Place a call from your business line (or have someone call you), answer it, then have a second caller dial your number. The second caller should reach your forwarding destination instead of a busy signal. If they still hear a busy tone, confirm your product name and try the matching code again.

Your destination choice depends on who handles the second call. Forwarding to a cell phone works if you can take calls on the go. Forwarding to a coworker works if you have one. Forwarding to an answering service or automated receptionist works when you want calls handled even while you are tied up.

One caution: a busy line usually means you are already talking to a customer. Think about whether the second caller needs a live handoff, a message-taking service, or just a professional greeting with a callback promise. That decision shapes whether a simple forwarding destination is enough or whether you need a service that can answer, take messages, and book appointments.

• Test by being on a call and having a second caller dial in
• Confirm the second caller reaches your destination, not a busy tone
• If the code fails, verify your exact AT&T product name first
• Pick a destination based on who should handle the overflow call

Many owners keep their public AT&T number and forward calls to AllDayDesk, an AI receptionist that answers calls around the clock using the business information you save. Setup starts by choosing your business or entering its website, checking the details it pulled together, and hearing a personalized sample call. The sample is a demonstration only and creates no real booking.

Then you choose phone setup and follow the instructions for your phone service, which for AT&T means dialing the forwarding code above with your AllDayDesk destination number. You keep your existing number; forwarding just routes calls. Calls, transcripts, summaries, and bookings all show up in your dashboard afterward.

By default, new appointments go on the built-in AllDayDesk dashboard calendar once you have configured your services and availability. If you prefer Google Calendar, you can connect and authorize your Google account in Settings as an optional step. When the receptionist does not know an answer, a price, or an open appointment slot, it takes a message for you instead of guessing.

Keep in mind that busy forwarding only covers calls that arrive while your line is in use. If you also want coverage when you are simply away from the phone, no-answer forwarding with the same destination handles that case.

• Keep your public AT&T number and forward to your AllDayDesk destination
• Setup: choose your business, verify details, hear a sample, then set up forwarding
• Calls, transcripts, summaries, and bookings appear in your dashboard
• Appointments use the dashboard calendar by default; Google Calendar is an optional Settings connection
• Unknown answers, prices, or slots become messages, not guesses

The most common reason a forwarding code fails is using the wrong product's instructions. AT&T Phone for Business, AT&T Collaborate, and AT&T wireless all use different codes, and a code from one product generally does nothing on another. Find the exact service name on your bill or account page before dialing anything.

If the product name is right and the code still fails, the feature may not be subscribed on your line. Conditional features like busy forwarding are not always included with every plan, so contact AT&T support for your specific account to confirm the feature is available and activated.

Also check for conflicts with other features. On some phone systems, features like call waiting change how busy forwarding behaves, and voicemail can interact with conditional forwarding. If calls are going to voicemail instead of your destination, review which feature takes priority on your product or ask AT&T support to check the line configuration.

• Verify the exact AT&T product name on your bill first
• Confirm the busy forwarding feature is subscribed on your line
• Check for conflicts with call waiting or voicemail
• Contact AT&T support if codes fail after confirming the product
