TO ACTIVATE PER-CALL BLOCKING
Lift the handset and listen for the dial tone.
Press *67 (On a rotary phone, dial 1167.)
Dial the number you're calling as usual.
The person you've called will not be able to see your number displayed on their telephone display screen. Instead, a "P" or "Private" will be displayed.
Notes: You must dial *67 before each call you place. Otherwise, your phone number will be released to the person receiving your call.
If you have requested Per-Line Blocking to be put on your line, you do not need to dial a code to block your number each time. Your number will always appear as "Private." To override Per-Line Blocking (allowing your number to be displayed) on an individual call dial *67 before placing the call.
