Calling the U.S.A.

[pioneerVicki]

What have you found as the cheapest solution to making business phone calls to the U.S.A.? Anyone have a favourite phone card, or other idea. I have used a phone card in the past; but they have changed the rules a bit & if you don't use it quicker you can loose your purchase price.

Try Skype, its a free download and calls are so cheap. Skype to Skype is free.
I installed it on my website for customers to use if they have Skype.
