KNCTR Call any North American landline or mobile phone number for free, but not for fun
KNCTR is a free program that allows its users to call any number in North America completely for free. For those on a very tight budget, this program can be an excellent alternative to a traditional phone line. While the audio quality is great for phone calls, some users might be disturbed by the constant advertising on the program, as well as its intrusion into their lives. KNCTR requires a number of seemingly extraneous details to get started, making the entire endeavor feel less "free" than it is actually supposed to be. Still, the quality of the calls is great for its price, making this an easy choice for people that either don't have a phone or simply don't want one.
