The magic-jack (VOIP)is pretty good. If you have an old pc you can leave powered up all the time and don’t use it for anything else, it's a pretty good deal. I don’t recommend it if you have to plugged it in on a computer you actually use, lots of ads(spam); also, if you’re paranoid about a thirdParty tracking phone usage. I used Vonage for quite a while, it’s more reliable but way overpriced.
