How to change the IP address for a 3cx managed FQDN

[acolville]

We are changing our IP provider which will result in the external addresses for our PBX's to change.

What is the process to update the 3CX hosted FQDN ip address?

Dear acolville,

Assuming that you are using V15 pbx go to settings --> network --> public ip tab --> External IP Configuration field and change to your new ip address. After that, restart all pbx services to take effect.

*Please have in mind that the DNS propagation will take up to 24 hours to complete.
