Not sure what your point is as I certainly didn't badmouth Voipo. I currently work in telecommunications and have for many years and do understand circuit issues. If what ended up being a one hour outage bothered me that much I'd be shopping around for a replacement provider as we speak. Once you switch your phone service to internet these are the risks you take. It is an issue, however, that people calling the down number did not go to the failover phone and either got a fast busy or a recording. Also, there is no way to check the call history to see what calls were missed during the outage. That is a problem.
Am I satisfied with Voipo? Absolutely! I've referred people here before and will continue to do so.
