External IP change

[house1]

We made a change to the External IP this weekend and it is not being reflected by our
3cx Certificate
and
Our main issue SIP provider is thinking it is coming from our old IP

I know we can definitely cure this by backup, uninstall, reinstall but if we just force a Certificate Upgrade with this cure problem (ver 16-windows) ?

I don't know what this means. You changed internet providers, you changed IPs on your firewall, or you actually changed the IP in 3CX? You don't need to uninstall for any of them, but it would help in troubleshooting to know what you did. You also say it is not being reflected in your certificate but I think you mean DNS. SSL certificates are not typically issued to IP addresses. But the simple answer typically is to change 3CX from static to dynamic (STUN) and then I'd leave it until you see DNS update (can take up to 6 hrs). Then once you have the correct IP showing in DNS you can change it back.

For your trunk, 3CX should be using whatever it things your external IP address is unless you changed the setting in your trunk configuration so I'd look there.
