This application operates in the background, which means that after installing it, all you will see is the application icon in the notification tray. The application will only pop-up when you get an call from a number that is not in your phonebook.
This application will resolve most residential and commercial Canadian phone numbers.
This application will not resolve blocked or unavailable numbers, and it will not resolve cellular phone numbers as they usually are not listed online.
This application queries the CANADA411 directory.. so if the number calling you is not listed there, then the application will not resolve it.
