Hello LS and others.
I use something that I consider even better than Magic Jack and it is called Skypes. It can be downloaded for FREE and once installed you can talk through your computer to almost anyone in the world for free using computers mic and speakers. What makes it really nice is that if you have a web cam on your PC you can see a live image of the person that you are talking to at the same time. You can also make conference call as I have been on line with 6 (six) different people at the same time. The only hitch is that the others you want to talk to must also have Skypes. So much for the free version.
If you so desire you can buy another version which will allow you to place calls to anyones regular telephone still using your PC as your main connection. I did not purchase this one.
Oh, one more thing televised calls only work between 2 (TWO) people and with conference calls all you get is an icon for each additional person with whom you are talking and as each person speaks their icon blinks. Like I said the program is totally free so it cost you nothing to try.
