How to set up call forwarding on AT&T Business
On an AT&T Phone for Business line, dial *72, the 10-digit number, then #, to forward all calls. Use *92 instead to forward only unanswered calls, or *90 for calls that come in while you're busy, and dial *73# to turn forwarding off.
On an AT&T business mobile phone, you turn forwarding on in your phone's settings instead. Both are explained below.
Steps taken from AT&T Business's own help pages, checked October 29, 2026. See sources.
Which kind of AT&T line do you have?
The steps depend on the kind of AT&T line your number is on. AT&T Phone for Business (an office phone line) uses dial codes or your online account. An AT&T mobile phone uses the phone's own settings. AT&T's larger phone systems, such as Office@Hand and AT&T Collaborate, have their own apps and portals, so check with whoever manages your system.
AT&T Phone for Business
Forward all calls
- Pick up your office phone and dial *72.
- Enter the 10-digit number you want calls sent to, then press #.
- Wait for the confirmation tone. AT&T then places a call to the forward-to number. Forwarding switches on once that call is answered. If the line is busy or nobody answers, it doesn't switch on, so try again.
Forward only busy or unanswered calls
- When you don't answer: dial *92, enter the number, then press #.
- When you're on another call: dial *90, enter the number, then press #.
Turn forwarding off
- All calls: dial *73#.
- No-answer forwarding: dial *93#.
- Busy forwarding: dial *91#.
Manage it online
- Sign in to your AT&T business account online.
- Open the menu for AT&T Phone for Business and choose Manage my plan.
- Go to your phone features to view or change your forwarding numbers.
If you save your forwarding numbers in your online account, you don't need to type them in again when you dial the codes.
AT&T business mobile phones
iPhone: forward all calls
- Open Settings, then Phone, then Call Forwarding.
- Turn Call Forwarding on and enter the number under Forward To.

- Choose always forward, or When unanswered to forward only calls you don't answer after a few rings. Enter the number and tap Turn on.
Menu names differ from phone to phone, so yours may look slightly different.
Turn forwarding off
- Go back to the same Call Forwarding screen and switch it off.
How to test it
- Call your business number from a different phone.
- If you forward all calls, the forwarded number should answer and your own phone shouldn't ring.
- If you set up no-answer forwarding, let the call ring without picking up. It should move to the forwarded number instead of voicemail.
- If you also set busy forwarding, call again while you're on another call.
- If nothing forwards on Phone for Business, remember the forward-to number has to answer AT&T's confirmation call. Dial the code again.
Does it cost extra?
Whether forwarded calls cost extra depends on your AT&T plan, so check your plan or ask AT&T before you rely on forwarding for every call.

Your line answers 24/7 in your business's name, tells callers it's a virtual assistant, books jobs into Google Calendar and emails you a summary after every call, with the recording and transcript in your portal. Growth and above add text summaries and live transfer of urgent calls to your phone. Plans start at $49 a month.
