You're already familiar with Skype —the service that lets you make calls over the Internet for free — so this little gadget is a total no-brainer.
The ooma Core VoIP Phone System ($249) is a hub that allows you to use voice-over-Internet calling like a home phone — without all the monthly charges (except what you would pay for your Internet access, of course). Just hook up your ooma phone to your modem and you'll be up and running in minutes. Plus, ooma tosses in some pretty cool perks for using their phone system: Free call waiting, caller ID, voicemail, call forwarding, and the option to port your current number to your ooma hub. And you can make international calls on the cheap. Cheap, like starting at a penny a minute.
Seriously, in these troubled economic times, cutting out your phone bill could save you some serious dough, and that is never a bad thing.
