PrivatePhone is a service from NetZero Voice that assigns to you a free telephone number so you can give it out instead of your personal number. Calls to your PrivatePhone number will be answered by voicemail. Your voicemail messages can be retrieved either online or from a regular telephone. The service can't forward calls to another phone number.
Local phone numbers are available in your choice of area coes and cities.
