  What if you have more then a switch on the cluster?

  How does the migration gets decided? I am confused on how this works. I guess I need to read the code...

        Guys,
          further to this interesting discussion, please check out this wiki page 

        http://wiki.freeswitch.org/wiki/Freeswitch_HA

        there was an announcement at cluecon that improves Freeswitches ability to do HA-clustering.
        please can you update this wiki page with the information you have learned doing the pacemaker side of this.

        also keep the conversation going now, with this new information :)

          "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

          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).

            Many thanks for fast and substantial answers!
            Has established ipv4.ip_nonlocal_bind=1.
            Now there is no necessity to reboot FS or sofia profile.

            As a result it has turned out:
            1) Two servers FS which kernel works with the shared db through unix ODBC
            2) It Is realised Cluster-IP by installations Pacemaker
