Ok so iCall.com doesn’t let you call anywhere you want for free, but you can call Canada and the USA completely for free. This should save you just a little bit on your phone bill.

How to make free calls to Canada and the USA
Simply sign up with iCall.com. Their service will let you immediately start making your free calls. There is no purchase necessary, so iCall.com has already redeemed itself since it lacks the amount of international destinations that most Voip services offer.

Get Your Own incoming Number
You don’t exactly get your own income number, rather iCall.com has access numbers all throughout the USA that will allow you to receive calls to your iCall. The person who wants to reach you simply dials the access number and enters in the code given to you at signup.
