3CX Failover

[Goran Cvijanovic]

Hello,

I need to setup 3cx failover in case if AWS stops working, and it's not clear to me if I can do this with PRO license, or I need to use ENT one.
On the picture below I can see that failover is supported with ENT license only, but in several posts people describing difference between failover with PRO compared to ENT license, and the difference is in the FQDN update which is set to 6 hours for PRO and 5 minutes for ENT license.

Can someone provide me accurate info about this so I can better understand available options?

You can use 2 pro licenses (1 for each) or 1 enterprise.
+ the 6 hour vs the 5 min TTL if using 3CX FQDNs.

The better option is ent

Hi Goran,

For failover you will need an Enterprise license. The active PBX configuration is replicated and restored on the passive PBX, which must use the same FQDN (hence the same license key which is bound to said FQDN).

The low TTL of an Enterprise license also allows the passive PBX's IP to take over soon after the active PBX goes down
