I am trying to get rid my land-line phone service through my internet provider. I've come across the oBi110 adapter on
Amazon.com. I have several questions that I haven't found answers to: Can I port my land-line number through Google Voice without giving/using a cell phone number/provider; I do not want to port my cell phone number. Can I use my existing at&t 5 phone cordless digital phones with the oBi110 and still use all of the functions? I'm not tech savoy, how difficult is the setup? Is there any charges other than the initial l adapter charge? Thanks
