Your best approach is to contact AT&T directly and have customer service add both Call Forward No Answer and Call Forward Busy to your phone line.

Setup Instructions

  1. Dial 800.288.2020
  2. Verify your telephone number
  3. Press 0 to speak with a customer service representative
  4. Tell the representative that you would like to activate two features on your business's phone number: "call forward no answer" and "call forward busy"
  5. Provide the representative with the call forwarding number assigned to you by Numa

How to Confirm It's Working

Call your business's phone number from your personal phone. If nobody answers, you should hear your Numa Voicemail greeting.


Make sure you don't have an answering machine picking up your calls before they get forwarded.

If your business's phone line is part of a hunt group (multiple lines that ring until one is answered), you may need to set up forwarding on all the lines involved. Alternatively, you could remove your business phone line from the hunt group.

Contact your phone provider and have them double check that forwarding was set up properly and is active on your line.

No matter what, don't hesitate to contact Numa support! We'll happily work with you and your service provider to get you all set up.
