For those who obviously do not know, the magicjack device relies exclusively on internet connectivity speeds and has nothing to do with phone signal "strength".
The technology is called VoIP and if you have an internet connection that will allow you to watch a youtube video without jitter, then you can use MagicJack or Vonage flawlessly.
Now if Blackamooka was talking about a bad telephone line coming into his ma's house that prevented her dsl modem from giving fast enough internet connectivity to keep up the VoIP connection, that's a different story altogether. But such a problem would have also affected Vonage.
Again, if you have internet speeds that are greater than 512kbps (up and down), magicjack will work perfectly. Use Speedtest.net if you are not sure.
And I'm a Magicjack user as well...
