Pauly01 also wants the convenience of a regular telephone handset that he can just pick up and get a dial tone, especially downstairs away from the computer. He wouldn’t have that with Skype.
You might also want to consider a Bluetooth cellular gateway, which acts as an interface between one or more Bluetooth-paired cellular phones and either a single landline type phone, a cordless phone base station, or potentially your entire home’s wired phone system.
The two caveats are, one, if you’re going to integrate it into your home phone wiring, you have to physically disconnect the original Bell or other provider connection, because the telephone network injects voltage into the system, even if service is cancelled. But of course it’s completely straightforward to just hook it up to a cordless base station with multiple handsets. The other caveat is that with a cell phone and a landline, you have an emergency backup. With only a cell phone plus gateway, everything depends on the cell service. Also, no matter how many phones you have throughout the house, if there is a power failure and the gateway is down, unless it’s on a UPS the only phone that will work is your physical cell phone.
Those who are elderly or security-conscious might want to think carefully about ditching their landlines, but otherwise, any combination of VOIP or Bluetooth gateway may work fine.
