If I guess how this works correctly it'll only handle failover, threads will still be needed in the FreeSWITCH architecture. I think call state is written to the database in realtime, then if FS fails a new instance of FS is started on another machine, reads call states from the database and starts threads for each call. Just a guess though. That'd mean it's read when FreeSWITCH starts up, so couldn't handle multiple servers on the same IP but would handle primary and backup servers.

I am not sure of the term "cluster IP" but here is the example

Load balancer have the actual public IP , while all FS servers has the same IP setup on the box as virtual IP and listens on the virtual IP. So in other words, all the FS servers are listening to the same IP address through out the architecture.
