Hosted 3CX firewall ports

[jbardon]

I am setting up a Hosted 3CX on an internet connection that has a very stric firewall policy. so no dought ports 5060 UDP will be blocked etc..

My assumtion is that if you are using an SBC you dont need to worry about the onsite firewall.

If i am wrong i would apriciate some feedback on what needs to be set up.

Is there a list of firewall ports that need opening in order for the onsite phones and SBC to connect to the hosted server?

Many Thanks

Jon

You don't need to open any inbound ports in your office firewall if using an SBC. If you do need to allow outbound connections, I suggest allowing all to the 3CX server IP, or there is a list at https://www.3cx.com/docs/ports/.
