[Freeswitch-users] HA clustering solution?

Configuration: that should be easy using XML CURL to load what would
otherwise be in the conf/ XML files. I would strongly recommend looking
at this.

Call state I wouldn't like to comment on, I have not looked into it. I
would imagine it's unlikely to succeed based on the uuid of each call
only being known to the handler FreeSWITCH instance. I could have my
assumptions wrong of course.

I take it incoming calls would be asked to try each of several IPs in
turn until a connection is successful? Else you would need to "notice"
one instance was no longer active and ask whomever was routing calls to
it to divert.

I still prefer the idea of 2+ proxy boxes. It would be simpler to add
more as load increases, and far simpler to add additional IVRs (FS) into
a backend pool. Heartbeat solutions have potential issues such as single
point of failure and split brain.
