The Linksys PAP2 is a little box that turns any home phone into a full-fledged VoIP phone. It's so simple: You just plug your home phone into the PAP2's jack and plug the PAP2 into your home network. That's it; your hardware setup is done. The real magic (and work) lies in the VoIP service we'll use: Sipgate, a VoIP service that gives you a free phone number.
When combined with Google Voice, it's as perfect a solution as $0/month will buy you: Sipgate gives you free incoming calls and Google Voice gives you free outgoing calls. You won't notice any difference when it comes to receiving callsâ€”your home phone will ring, just like it did with your landline. Making outgoing calls is a little less convenient because you'll need to use Google Voice's website to set up calls but that tiny trade leaves you completely free of monthly dues.
