What are the FQDN for 3CX Update and licensing servers? Customer wants to restrict firewall.

I know I've seen a post about this before but cant seem to find it when I need it.

My customer wants to restrict access to his network from only allowed addresses. What are the FQDNs of the servers he needs to allow?

From the installation notes for Windows I see:

The 3CX host machine needs internet connectivity to activation.3cx.com and
downloads.3cx.com/* on port 443 (HTTPS) for activation, updates and other info.

Are there any other addresses?

downloads.3cx.com, activation.3cx.com

Thanks for that. Will I also need to allow the webmeeting FQDNs also?

Yes allow these.

You may also want to allow the 3CX STUN servers for firewall testing, If I remember rightly? Someone may be able to confirm or deny that

downloads-global.3cx.com and activation.3cx.com is the bare minimum.

There are other URLs dependingly if been used by the customer.
From the reputational defence system (RED), 3CX Provided SMTP server, STUN servers if on dynamic IP, WebMeeting, RPS Provisioning and maybe others I might have now missed ad-hock.
