The question means if it is negligently to offer HA PBXACT but we are not available 24/7 at the moment.
In your experience. Is a HA PBXACT enough regularly to offer the customer 24/7?
Sure there can be other problems like Trunk is down or so, but this can also be failovered to other numbers. But how probably is it possible that both nodes at the same time do not work anymore when no one changed anything in the running pbx?
In your oppinion, would you offer HA when you know, that you are not available as a person 24/7 ?
If you are available 24/7 on short notices you don’t need HA. Generally HA will fail over in an orderly fashion, so you can service the failed node at your leisure. If your customer demands an SLA that requires 24/7 support that you can’t provide, Sangoma does offer that.
We live in Austria, i know that you do not have Technical German Speaking Employees at the moment. This is the reason why we cannot give the SLA to Sangoma for now. No Customer wants to have English Support if there is a problem.
Sounds like this is the thing i need. Does the HA Module only check if the other server is up? Or will it also check if asterisk and all other services are running? It should also failover when both PBX are online but a service crashed and will not come up anymore because of any reason.
It exactly does that.
It checks different services like Asterisk, mysql, httpd, etc and will fail over the service to the other node if it crashes.
So if Asterisk crashes, the other server will take over that service.
Be warned, unless you are using VMware or similar, failover does not occur on complete power loss. IPMI as a fencing method is not sufficient. Standard tools (like networked PDUs and whatnot) are not supported. Sangoma quoted me something like $5000 last time I asked for this to be implemented to fill in for what IPMI fencing lacks. I would seriously advise against relying on the FreePBX HA module unless you’re in a virtual environment. And even then, test test test test test and then test one more time.
