1. How many people have a VoIP solution on their phones to use over WiFi in a case like this? 2. What is the percentage of homes with twisted pair landlines do

  afaik most carriers in the US offer a form of voip over wifi. it needs to be enabled for your phone.

    This is called "Wi-Fi Calling" and it also seems to be down for those affected. (n =~ 150 phones I'm tracking)

      On my phone in Seattle Verizon Wi-Fi calling doesn't work but FaceTime audio does.

        Yep. Wi-Fi Calling is a mix of GRE/IPSec tunnels to carrier servers (which were still functioning during the outage) that then hook into cellular infra on the backend (which wasn't working). On my firewall, I was seeing phones make that GRE tunnel connection, but it was just a gaping void after that. FaceTime does not use cellular infra at all (except as a potential IP network interface)
