Hello, will one of the Obi devices hook up to the phone line that previously came out of my comcast router? This is a standard phone line that goes to several phones throughout the house. I have a Google Voice phone number and want to use that for the house phones. I just canceled my Comcast phone service. Since this phone line is close to my comcast router, I can plug my ethernet cable into the device, and then have output via house phone line. Thanks
