The magicJack device, about the size of a box of Tic Tacs, has a USB plug on one end and an RJ-11 phone jack on the other. I had to connect mine to a Windows PC, but Mac OS X drivers should be ready soon. After USB plug meets USB port, you'll wait a minute or so while the magicJack software gets automatically loaded. Those who already have magicJack will be happy to know that the company says a firmware rev released while I was testing makes the hardware more resilient to problems caused by fluctuating electrical levels in foreign countries. It also installs hardware echo control, which taxes your CPU about 50 percent less than before.

If this is your first time using the device, you'll have to run through a registration process. You either request a new number or ask to have your existing number ported (porting availability depends on where you are, takes up to 60 days, and has a $10 surcharge attached); then you input the information necessary to make e911 work (so that emergency services know where you're calling from). The process should force you off the couch for 60 seconds or so, but that's it: no phone configuration, no Internet router tweaks. Low-tech folks who just want a cheap phone can just plug a regular analog phone into the magicJack's RJ-11 port and start dialing.

Those who want a little more will find a fairly impressive array of features in the magicJack software, including caller ID, call waiting, call forwarding, and voice mail that will respond even if you're not online. The software supplies a softphone that works through a headset and microphone connected to your PC. Compared with business VoIP, this might be a light feature set, but for home users it's plenty.
