I don't know anything about Magic Jack either, but I do have an opinion on computer generated phone services. If your computer or provider goes out you can't use them. In our case we have Roadrunner Broadband thru our cable company, and several times they have had to shut down or went out for one reason or another; had we had their phone service we would have been without the use of that phone. For that reason we've decided not to switch our land phone to that type of service. We do have cell phones that we can use but prefer to keep the land phone. Having both gives us better options to make calls.
Another note here: Following the recent little earthquake that we had here, the cell phone systems were jammed within seconds after the shaking stopped; supposedly the systems overloaded and the cell companies shut the systems down. It was an hour or more before they worked again. We didn't try the land line - but it did ring several times without it going to the recorder. Others had this happen too, it was reported on the news. This reinforces the cautions about being prepared ahead of time. Your phones probably won't work following a disaster and you can't call for help, you will have to handle your emergency yourself as best you can. If your electricity is off you also can't use your computer. Edey
