      AT&T Call Forwarding Instructions

      Pick the kind of call forwarding you want from the options below. Please note that codes are subject to change by AT&T. 

       

      Unconditional (Standard) Call Forwarding - Calls are immediately forwarded to the answering service without ringing to you first.

       

      Conditional Call Forwarding - Calls will ring to you first and if you are unable to answer the call, it will forward to the answering service instead of going to your voicemail.

      Note:AT&T does not offer the option to change the amount of rings before transferring the call to the answering service 

      Best practice is to save the on and off numbers as contacts in your phone so turning on and off the answering service is as easy as clicking a button!

      AT&T Business Line/Landline

      • Call 800-288-2020 and from there you will get an automated system that will link your phone number to the account. The automated system will recognize it is a business landline and will ask what you are needing.

      • Request a repair

      • The system will then forward you to the customer service representative and then request that you would like your calls forwarded from the account phone number to your new account number.
