Nu Frontier also offers Voice Over IP Services. Of particular interest is the new Wireless Internet phone:

This device can be used at Home, at the Office, and at a number of Hotspot locations throughout Montreal and across the country. It also allows you to have more than one area code for each phone. For only $30/month any call throughout North America is a local call. You can call land lines, cell phones, or other Voice over IP phones. All calls between subscribers to Teliphone are free no matter where you are in the world.
