Setting up failover

[Alphabetic]

Hi All

After ive installed PBX2 it says to restart system service - is this required or can I just refresh license on PBX1?

If you're referring to the DNS record update then I'd recommend restarting the system service on PBX 1 (primary) after you've completely the passive server's setup.

It should just take a few seconds and will not drop any calls. It will however prevent calls from being logged while it is not running.
