[Freeswitch-users] FS HA-cluster

[Steven Ayre]

"As server FS work with share db, there is an impression that at switching
Cluster-IP with active on
a passive, passive server can pick up session begun on an active server (the
necessary data about
current sessions takes from the share db). Whether So it?
Testing has shown that at switching Cluster-IP on reserve FS, that does not
process session which
have begun on first FS :("

Sorry, but that's not currently possible as the call state information is
held in memory, not the shared database, and has execution threads started
for processing the signalling/media which aren't duplicated on the other
machine(s).
