Anyone have experience getting rid of their home phone and replacing it with Obihai? Sounds great in theory but Im not very techie and even the description sounds over my head. I see one with 1 port on amazon thats cheaper than one with 2 ports, what does that mean lol? Can I only hook up one phone to the one with only one port? I have 2 cordless in my house, one hooked into the phone jack and one just plugs in the bedroom, not sure the set up I would need. Also, I read you can keep your exisitng phone number but some of the reviews on amazon said they couldnt. Also my modem is in the basment, can I only hook the phone up down there? Thanks!!!!!!!!!!!!!!!!!!
