How Can I Block a Phone Number From My Mediacom Home Phone?by Palmer Owyoung
Junk mail, spam e-mails and telemarketers--these are unfortunate nuisances in the information age. Nobody likes to be interrupted in the middle of their evening dinner by a phone call only to find that it's someone trying to get you to upgrade your long distance plan. If you have a Mediacom phone plan it's easy to block these calls.
Install Caller ID
This feature is free with a Mediacom phone calling plan, but you will still need to purchase the equipment to display the caller ID or you will need a phone that has this feature built in.
Block Unidentified Numbers
Press *77 to block unidentified numbers. Activation of this feature will be confirmed by two beeps. To deactivate, press *87.
Block Known Numbers
If your caller ID identifies someone that you don't want to speak to, you can block the number by pressing *67.
Block Numbers Permanently
If you wish to permanently block numbers, you will need additional equipment such as a Caller ID Manager. This device plugs into your phone and will block between 175 to 500 phone numbers that you have designated as undesirable.
