We've been using a free Google voice account coupled with an OBi200 phone adapter for almost a year now and feel like it's a good land line option.

There have been a few times when the internet was down we had to use a mobile phone to report the outage.

One feature we like is the fact that we can send and receive text messages on our home computers. A caller ID message pops up when someone is ringing in and voice messages get transcribed and emailed to you.

There was no land line phone choice in our area but it seems like this option is almost as good. We do pay 25 dollars per year to access the 911 system but other than that the phone adapter has paid for itself when compared to the cheapest land line price.
