New to 3CX. How does 3CX implement failover or high availability in its Enterprise edition?
Can it do real-time replication to a branch site or colocation?
If not, can it do automatic or manual failover o a branch site? How well does it work?
Thank you

With the Enterprise edition (single licence which support x2 activations) I would say it works a lot better.

There is a standard fail-over option with the PRO licence however it was a real nightmare to setup and although I did achieve it there was a lot to configure (Share between systems, Windows scripts, DNS etc).

This will cover a lot of what is required for the fail-over:https://www.3cx.com/docs/failover/ with an Enterprise licence. I have however given some additional points below:

* Ideally the environment should require SPLIT DNS:
https://www.3cx.com/docs/creating-fqdn-split-dns/

* 3CX Provided FQDN and SSL is mandatory.

* There is no Active/Active setup for 3CX failover. You can only configure it as active/ passive.

* The IP address setup should be static and configured accordingly in each PBX used.

* The Failover System will register at start-up the new IP address on your FQDN which is used for external devices to connect to (STUN, SBC, 3CXPhone, Presence).

I hope this helps.
 
Thank you very much.
 
Can the passive host be located in a different WAN/branch office?
 
I think I found the answer in your link. Thank you again.
