AUTOMATIC CALLBACK allows you to dial a code to have your phone continuously attempt to redial a busy number that you tried to call. When the line is free, you will be alerted with a special ringing, and a call will automatically be made. You can also use AUTOMATIC CALLBACK to redial the last number you called.
To use AUTOMATIC CALLBACK:
1. Hang up, then lift the receiver and listen for a dial tone.
2. Press *66.
3. If the line is busy:
Listen for three beeps or an announcement telling you the number is busy.
You will hear a short-short-long ring when the line is free.
Your call will automatically be made when you lift the handset.
