[Freeswitch-users] FS HA-cluster

[jay binks]

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 :)
