I have a Google Nexus One, onto which I have installed the 3CXPhone softphone. My plan is to use this phone as a cordless phone to my home line, which is basic analog POTS. I will need a SIP FXO adapter to do this. After a bit of searching, I came across the Cisco/Linksys SPA3102. Will this device do what I want? Is there something better for what I want to do?
