Cheapest voip option to call North America
There are a lot of companies which offer voip calls to land line numbers and mobiles in North America and the rest of the world as well and I have used a few myself but in the end I have opted for skype as their voice quality is the best and beats competition by a lot of margin. The best thing about skype is that it even works with a 64kbps connection and even on a dial up connection with a little bit of lag which no other voip service provider is able to do. Skype in is a service which allows you to get a number of your own which any one can call and you can choose between different locations like Canada, USA, UK and a lot of other countries.
