How to Use Call Blocking With AT&Tby Traci Joy
One of the calling features offered by AT&T is call blocking. This feature allows you to block your number from displaying on someone else's caller ID when dialing out, block incoming calls from specific numbers or block calls from others who hide their numbers from your caller ID.
To Block Your Number When Dialing Out
Press *67 on your phone and listen for a dial tone.
Dial the number you are calling.
Repeat this process for each call that you make, as this method will block your number for one call only.
To Block a Number From Calling You
Press *60 on your phone and listen carefully to the announcement. It will tell you whether your service is on or off.
Press 3 to turn this service on (or off), then press 1 to hear the numbers that are on your blocked list, if any.
Press #01# to add the last number that called you to the list.
Press # to add a new number to your list. The voice instructions will tell you to enter the area code and number, and then press # again.
