I know I need to be able to resolve these FQDNs for activation. However, my security team needs to know the exact ports to open and what services may be needed (FTP, SFTP, TFTP?). Also, are these 'one and done' or is there messaging to make sure the licensing is up today?

These are the ports used by 3CX. https://www.3cx.com/docs/ports/
Depending on your requirements, you may not have to have all forwarded.

Thank you. Let's see if my security team can open this up with this info!
