Get a multiple handset wireless phone for in your house. (Used of course)
Panasonic makes good ones with three or four handsets if you want that many. One base unit that gets plugged into the magicjack and the other handset(s) have their own charger.
Awesome. Thanks for the info. I've been wanting to get another cordless. I used to have one, but I made the mistake of talking during a lightning storm. It knocked out the phone and nearly deafened me in one ear; plus I could not talk to clients and use the laptop at the same time, since they used the same frequency. I think they've solved that frequency problem since then (2004).
