The box with NAT would be the only thing that hangs onto sessions - everything expires at 24 hours, so that would be gone through the weekend (and some work weeks). I would think it's failing to dial when I lose VZW or doesn't think it needs to and a reboot of the phone forces it to. The phone may have an IPsec tunnel lingering, I suppose.

IIRC, the Wifi calling stuff works over IPSec from the devices back to a concentrator device.

Are you able to look on your network firewall/router/nat device and see if you have lingering IPSec sessions hung open, or if there's a network ALG that might be playing a part?

I used to have issues like this with T-Mobile and UMA.

If someone from Verizon Wireless specifically for WiFi calling could reach out to me to fix our devices I would appreciate it. The WiFi calling works just fine when we reboot in the office, but it will never reconnect (ie we leave the office, get 4G, come back). I've opened 3-4 tickets with no resolution.

Hello,

Is anyone from verizon wireless on here. clients across our network started complaining 2 weeks ago that wifi calling stopped working. below are some pings at traceroutes to wo.vzwwo.com <http://wo.vzwwo.com> which fail. the first set is with our normal DNS servers and the second set is using 8.8.8.8
