How Can I Block A Number From Calling My Landline?

You typically should check your local phone book or get in touch with your phone company. Many offer call block along with regular phone service. You usually find detailed instructions in the white or possibly yellow pages. Also, if someone's actually harassing you, consider calling the phone company so as to report it.

Another option is a caller ID manager or similar product. Many Caller ID's often display a number as an "anonymous" caller yet others help you step around this. You can program such instruments to simply ignore certain callers, not answering their calls with no ringing sounded off either. Blocking anonymous numbers is another feature as well. You can also route unanswered or even blocked calls to your voice mail if desired.

Typically your best bet would be asking your phone company service provider.

My local carrier (at&t) does not block cell numbers or out of area numbers.  Therefore, the call block service that I pay for is virtually useless!!
