AT&T's call-blocking service allows users to block calls from individual numbers. The user calls a special access number, then adds the block through the phone's keypad. When the blocked caller calls the number, they hear a message that the number is not accepting calls. When the user wants to unblock the number, they can remove the block from the same menu.
Dial "*60" from a touch-tone phone to enter the selective-call-rejection system.
Press the "*" button to unblock a number.
Dial the number you wish to unblock.
Press the "#" key to confirm you want to unblock the number.
Tips & Warnings
- You can also access the system from a rotary phone by dialing "1160." Follow the voice prompts for unblocking the number.
- To unblock all numbers, dial "*80" or "1180" to turn off the call-blocking feature.
