Another issue with the VoIP setup is that the cable companies are not required to meet the reliability standards that POTS do. Short of a local wire being knocked down, the phone service will stay up during power outages. I believe the phone system has a requirement to back in service in less than 24 hours, were as the cable service doesn't have such a limit. At my house, we lost cable for 4 days until the cable company could replace the power amp that was knocked down.
