It has been about 24 hours and 3cx has not updated its name.3cx.us ip address for our test system. We are just trying out to see if the system will work for us. The installation is a google cloud install with an Ephemeral external ip that will change when we stop the instance. I'm hoping to test some SIP providers next, but it seems the 3cx softphone won't work without the FQDN. I've seen other posts about this, but no resolution has been posted except to wait. Maybe there is a cert issue for this process, but it definitely makes it challenging to demo.
