3Cx secondary SIP server

[Amit123]

Hi,
i would like to know how can i add in 3CX provision a secondary SIP server in case the main SIP fails,
i can add it manually on grandstream 2130 but obviously i wanna make it under provision;



thanks.

You wouldn't.

3CX has a failover capability that works without needing that, as it uses DNS failover.

None of the supported config templates can do that, and not sure you should.

Thank for the reply,
so should i just alter my DNS registration?

If you use a custom FQDN, yes, with a TTL of 5min.

If you use a 3CX FQDN, you do not have access to that.

Also, username and passwords won't work on another system unless it's an exact copy, and a 3CX also. Which is why I said the failover is better.

If you are interested in setting up a 3CX Failover configuration, I recommend going through this documentation: https://www.3cx.com/docs/failover/
