PhoneFree runs as a browser plugin, so placing a call is as clicking a person's name. PhoneFree also has integrated voice mail that can be sent to any user with an email address. The recipient does not need any special software to listen to the message.
With the introduction of Active PhoneBook users can now create their own groups and know immediately when their friends and family come online. They can also represent themselves with their own photos in their friend's Active PhoneBook.
