# AT&T Phone for Business

> How to forward AT&T Phone for Business calls to Answering Agent and how to move your AT&T Phone for Business number over.

Two ways to get your AT\&T Phone for Business number to your agent. Forwarding keeps AT\&T Phone for Business as your phone company and sends calls over. Moving the number (porting) makes Answering Agent your phone company for that number.

## Forward calls

| Action                      | Dial   |
| --------------------------- | ------ |
| Forward all calls           | `*72`  |
| Stop forwarding             | `*73#` |
| Forward when no one answers | `*92`  |
| Forward when busy           | `*90`  |

<Steps>
  <Step title="Pick a phone on the business line">
    Lift the handset on a phone connected to the AT\&T business line and wait for dial tone.
  </Step>

  <Step title="Turn on forwarding">
    Press \*72, enter the number you want calls to go to, then press #. On traditional business service you can also dial 72#.
  </Step>

  <Step title="Let the call go through">
    On traditional service the system calls the forward-to number for you. The feature only turns on if someone answers that call, so keep a person on the other end.
  </Step>

  <Step title="Turn it off">
    Press \*73# to stop forwarding all calls.
  </Step>

  <Step title="Or manage it in the portal">
    Sign in to your online AT\&T business account to store forwarding numbers and manage features you cannot set with a star code. Once numbers are stored online you do not have to re-enter them by phone.
  </Step>

  <Step title="Call your business number from another phone">
    Answering Agent listens for the call. When your agent picks up, the phone numbers step in your dashboard turns green.
  </Step>
</Steps>

### Good to know

* No Answer Call Forwarding turns off with \*93#. Busy Call Forwarding turns off with \*91#.
* Safe Call Forwarding sends calls elsewhere during an outage: \*372 to turn on, \*373# to turn off. Deactivating loses all stored numbers.
* Exclusive Call Forwarding routes up to 20 chosen numbers: \*63# to turn on, \*83# to turn off. The 20 numbers are chosen in the online account, not by phone.
* On traditional AT\&T business phone service, the forward-to number must answer for activation to succeed. If it is busy or unanswered the feature quietly does not turn on, so test it before relying on it.
* Dialing rules for the forward-to number on traditional service: long distance needs 1 plus the 10 digits, non-long-distance numbers needing an area code use 10 digits, and local calls use 7 digits.

## Move your number

Start the move from **Dashboard**, then **Phone numbers**, then **Add a number**, and choose **Move my number**. Upload your latest bill and we read the details for you. Have these ready:

| What the carrier asks for  | Where to find it                                                                                                                                                                                                                                                                                               |
| -------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Account number             | On the AT\&T bill for the business phone account, and in the online AT\&T business account. AT\&T's consumer guidance also applies: the number sits under the page number or issue date on any bill page.                                                                                                      |
| Transfer PIN               | No. AT\&T does not publish a customer-generated transfer PIN for business wireline numbers. The Number Transfer PIN is a wireless-only mechanism. For a business landline the new carrier submits a Local Service Request (LSR) to AT\&T on your behalf, using the account number and customer service record. |
| Extra signed authorization | Yes                                                                                                                                                                                                                                                                                                            |
| How long it takes          | Minimum 3 business days for AT\&T Local Network Services and AT\&T Business VoIP, minimum 5 business days for AT\&T Digital Link, measured from a clean request to the requested completion date                                                                                                               |

<Warning>Do not cancel your service with AT\&T Phone for Business until the move is complete. A cancelled number can be lost.</Warning>

### Watch out for

* This is a carrier-to-carrier process, not a self-service one. Your new provider drives it; you mainly supply the account number, service address, and a signed authorization.
* AT\&T requires the gaining carrier to hold a Letter of Authorization from you before it submits the request.
* Which AT\&T entity holds the number decides the process and the interval. The gaining carrier checks NPAC for the SPID: 7421 is AT\&T Digital Link, 7125 is AT\&T Local Network Services and AT\&T Business VoIP.
* Any pending order on the account causes the port-away request to be rejected. Pending orders take 30 calendar days to clear on SPID 7125 and 30 to 45 days on SPID 7421, so open change orders can stall a move by a month.
* Requests received after 3:00 PM local time count as the next business day.
* AT\&T confirms a clean request within 24 to 48 hours depending on the entity, but confirmation is not completion.
* For AT\&T Digital Link, if you are disconnecting AT\&T entirely the disconnect desk has to be contacted separately in addition to the port request.
