You connect your phone to your Internet modem and then you can make unlimited calls to any land or mobile number in the United States, Canada and Puerto Rico. If someone calls you and you are not available, the person can leave you a message in your voice mail account. A few methods are available for retrieving your Comcast voice mail.
