Asterisk/centos failover

Hi,

What is easy and good mechanism to manage failover between two asterisk system.
Both server ready with Centos 8 and Asterisk 18.4

Thanks

I’ve worked on systems that used ‘floating’ IP addresses and applications like DRDB, heartbeat, and corosync.

I’ve also worked on systems that ‘fronted’ Asterisk farms with applications like OpenSIPS.

We never had an actual ‘in production’ fail, but OpenSIPS was a lot easier to configure and introduced lots of routing features that made operations, load balancing, and debugging easier.

OpenSIPS has many features, we were using only a very small subset.
