[siscom]

Good Afternoon Colleagues
I hope you are doing good and safe. May i know if it is mandatory that 3CX server with Pro license must be connected to Internet 24x7 ?

Best Regards

Yes, for activation and updates.

Hello siscom,

Alternatively, you may only allow required ports for activation and updates. 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. To send emails via the 3CX SMTP the machine needs to allow outbound TCP:2528.

Hello Colleagues
Thanks for your replies . If it is required for activation , updates check and send emails , May i know how frequently 3CX server make heartbeat to 3CX activation ?

The case that the internet connectivity at my customer may disconnect for 1 or 2 days and i don't want to push him to get dedicated internet connectivity to 3CX server.

So can 3CX server disconnected from Internet and from 3CX activation server for 2 to 3 days with maximum to 7 days without affecting the operation of 3CX system (Call Ceter in my case) knowing that all users connected to 3CX server are connected via LAN connectivity and no need neither to send emails or nor for any user to connect to 3CX server from WAN (Internet) side.

Thanks in advance.

Best Regards

@siscom If it's just for 2-3 days, it should not be a problem. But beyond that you might lose the activation and it will downgrade to Standard 4SC if that happens.

Hi John
Thanks for your feedback . So is there any documentation from 3CX confirming this so i can officially share the information with my customer ?

Best Regards

 

[JohnS_3CX]

No, there is no official documentation to share on this, it is just advisory.

I cannot predict exactly when the license check will fail, and we do not recommend to run 3CX offline, it has to have internet access to work as designed so don't treat this as a non-issue if you want to be on the safe side. Inform the customer that that the system was designed this way so they are fully aware.

Well Noted John . So i will advice my customer to have backup internet connection if primary internet connection fails.

So what is Internet quote that should be dedicated to 3CX per month ? For example , Does 500 Mega Bytes per month internet quote is enough for 3CX to heartbeat with 3CX activation server ?

Best Regards

 

[JohnS_3CX]

There's not preset quota that I can suggest, keeping in mind the instance is designed to be connected to the internet constantly, so it may check for system updates, blacklist updates, firmware updates, it's not just the activation server.

You can do what you suggest and see how it goes, monitor your own usage and adjust accordingly
