Call blocking gives you the option of blocking calls from unwanted callers. Depending on your phone service provider, you can block up to 12 telephone numbers. You can even block the last caller even if you do not know the number. You can deactivate the feature at any time by using a special code. While the feature is deactivated, callers from previously blocked numbers will be able to call you. After removing call blocking using the code, you can reactivate it when you desire.

Pick up your landline phone and listen for a dial tone.

Press *80 on your phone's handset. If you are dialing from a rotary phone, dial 1180 instead.

Listen for confirmation and hang up the phone.
