You can save time dialing numbers over and over. Your phone rings as soon as the line is free, and automatically connects you to the other number.

How to use

  • When you hear a busy signal, press and release the switch hook. Listen for a special tone.
  • If you have already hung up, lift the handset and listen for a normal dial tone. Press *66. (On a rotary phone, dial 1166)
  • If the line is still busy, hang up. Your phone will check the number for up to 30 minutes. A special call back ring alerts you if and when the line becomes free within the 30 minutes.
  • Lift the handset to automatically receive the call.

To cancel your callback request

  • Depress the switch hook and release. Listen for a special dial tone.
  • If you have already hung up, lift the handset and listen for a normal dial tone. Press *86. (On a rotary phone, dial 1186)
  • Listen for the confirmation tone or announcement. Hang up.
