AT&T Business Line Call Forwarding
AT&T business line call forwarding sends calls that come in on your business number to another phone, such as a cell phone or an answering service, so you can keep the same public number. The exact steps depend on which AT&T product you have. For AT&T Phone for Business, dial *72, the 10-digit destination, then # to forward all calls, and *73# to turn it off. For no-answer forwarding use *92 plus the destination and #, and turn it off with *93#. For busy forwarding use *90 plus the destination and #, and turn it off with *91#. AT&T Collaborate uses different codes: *72 plus the destination for always forwarding, *62 plus the destination for busy forwarding, and *92 plus the destination for no-answer forwarding, with *73, *63, and *93 to disable each one. Always confirm your exact product name on your bill or in your AT&T account before dialing, because wireless lines and other AT&T services use different codes. Forwarding is set up from the business line itself unless your product offers a portal or remote option.

Why business owners forward their AT&T line
Most owners answer their own phone, but there are hours when nobody can pick up: on a job site, driving between customers, or after closing. Forwarding lets calls follow you or go to a service that handles them, while customers still dial the number they already know.
There are two main styles. All-call forwarding sends every incoming call straight to the destination. Conditional forwarding only steps in when the line is busy or nobody answers, so normal calls still ring at your desk first. Which one you want changes which code you dial.
- Keep your advertised business number even when calls are handled elsewhere
- Forward all calls, or only busy and unanswered calls, depending on the code you use
- Turn forwarding on and off from the business line whenever you need to

Codes for AT&T Collaborate
AT&T Collaborate is a hosted business phone product, and its feature access codes differ from AT&T Phone for Business. An administrator controls which features are available on your line, so if a code does not work, check with whoever manages the account.
These codes apply only to Collaborate. Do not use them on an AT&T wireless line or assume they match other AT&T landline products.
- Always forward: dial *72 plus the destination; disable with *73
- Busy forwarding: dial *62 plus the destination; disable with *63
- No-answer forwarding: dial *92 plus the destination; disable with *93

First, identify your exact AT&T service
The most common mistake is dialing codes meant for a different product. AT&T sells wireless service, AT&T Phone for Business, Collaborate, and other arrangements, and the codes are not interchangeable. Check your bill or your AT&T account portal for the exact service name before you start.
If you are unsure which product you have, or a code returns an error, contact AT&T business support and ask for the call forwarding instructions for your specific service. Conditional forwarding in particular is not available on every plan, so confirm support before relying on it.
- Check the service name on your bill or online account
- Match your product to the right code list above
- Confirm with AT&T support if a code fails or your product is not listed

Forwarding your line to an answering service
Forwarding is how you keep your public AT&T number while calls are handled by a service. You point your line at the service's number using the codes above, and callers never see a different number.
AllDayDesk is this site's own AI receptionist. It answers calls around the clock using your saved business information. Setup works by choosing your business or entering its website, checking the details it found, hearing a personalized sample call, and then choosing how to connect your phone, which is where your AT&T forwarding codes come in. Calls, transcripts, summaries, and bookings show up in your dashboard. New appointments go on the built-in dashboard calendar once you have set your services and availability, and an optional Google Calendar connection is available in Settings after you connect and authorize your account. When the service does not know an answer, a price, or an opening, it takes a message for you. Changes to existing appointments are passed to you as requests, not confirmed changes.
If you want transfers to your cell phone when something needs you personally, you configure the destination and the rules in advance. A transfer depends on your phone being reachable, so pickup is not guaranteed.
- Forward to the service number using your product's codes
- Keep your existing public number, no number change needed
- Review calls, transcripts, and summaries in the dashboard

Testing and turning forwarding off
After activating forwarding, call your business number from a different phone and confirm the call arrives where you expect. Check whether the greeting you hear is the one you intended, whether that is your own voicemail or a service answering.
To stop forwarding, dial the matching disable code from the same business line: *73# on AT&T Phone for Business, or *73 on Collaborate. If forwarding was set to busy or no-answer only, disable that specific condition with its own code. Leaving a conditional code active is easy to forget, so it is worth a quick check after any change.
- Test with a call from another phone after every change
- Disable all-call forwarding with *73# (Phone for Business) or *73 (Collaborate)
- Disable busy and no-answer conditions with their own codes

More questions, answered
Do the same codes work on my AT&T cell phone?
No. AT&T wireless lines use different forwarding codes than AT&T Phone for Business or Collaborate. Check your wireless account or device support for the codes that apply to your mobile line, and confirm your exact service before dialing.
What is the difference between *72 and *92 forwarding?
On AT&T Phone for Business, *72 forwards all calls immediately to the destination, so your business line does not ring at all. *92 forwards only when nobody answers within the normal ring time, so ordinary calls still reach you first. Pick based on whether you want the line to keep ringing.
Can I forward my AT&T line to an AI receptionist?
Yes, if your AT&T product supports forwarding to a standard 10-digit number. You dial your product's forwarding code with the service's number as the destination. AllDayDesk answers using your saved business information, and you can hear a personalized sample before connecting your phone.
Why did my forwarding code give an error?
The most likely reasons are that the code belongs to a different AT&T product, or that the feature is not enabled on your line. Collaborate features are controlled by an administrator. Confirm your exact service name and contact AT&T business support if the code still fails.
Does forwarding change my published business number?
No. Callers dial your business number exactly as before. Forwarding happens on the AT&T side after the call arrives, so your advertising, listings, and signage all stay the same.
Hear how your calls could sound
Set up takes a few steps: pick your business, check the details, and listen to a personalized sample receptionist for your own company before you decide anything. If you like what you hear, connect your AT&T line with the forwarding codes above.
