Use AT&T Repeat Dialing

Learn how to use Repeat Dialing (*66) when you make a call and get a busy signal.

Set up and use Repeat Dialing

If you make a call and get a busy signal, you can use Repeat Dialing to call the number again for the next 30 minutes. When the line is free, you'll hear a special short-short-long ring.

You can add this feature to your monthly service or use Repeat Dialing on a pay-per-use basis.

Activate

  1. Hang up the phone after calling and getting a busy signal.
  2. Pick the phone up and at the dial tone, press *66.
    • If the line is free, the call will go through.
    • If the line is busy, you may hear a message. The feature will retry the line every 60 seconds for the next 30 minutes.
    • When the call goes through, you'll hear a special ring. Two short rings and one long ring. When you hear the special ring, pick up your phone.

Deactivate

You can stop Repeat Dialing before the called number is free:
  1. Press *86 at the dial tone.
  2. Hang up after hearing the recorded message.

Helpful hints

  • If you pick up the phone after the special ring and hear a busy signal, the other person is already on another call.
  • Repeat Dialing works for more than one busy number at a time and signals you when one is free. It can't tell you which number it is when you hear the special ring.
  • You can still make and receive calls while Repeat Dialing is working to call your party.
  • If calls are dialed to a number outside your local calling area, usage or long distance charges may apply.
