Not sure if this was mentioned, but another great thing about Skype is the ability to purchase "credit" and call any phone anywhere. I usually purchase $10 and that lasts a long time. Calling to the US is 2 cents a minute...that usually is way more than needed! The quality is almost always very good as well. I highly recommend it. Just make sure you don't let them auto-deduct a payment from your card once your credit runs low
