I do dozens of VZW WiFi calls a day. My phone is behind NAT, no problem. It's probably 50/50 where the call starts on WiFi vs switches to WiFi after ~3 seconds from the poor VZW signal.
Same here, one of my cell operators uses VoWiFi for their calls and SMS's. As long as I am on wi-fi though, all calls and SMS's are sent over wi-fi. I'm doing NAT44 + native IPv6, no special holes punched in my Mikrotik router (the cell provider is doing WiFi Calling over IPv4). Mark.
