Server redundancy using flip1405

Is anyone using the flip1405 script to implement server redundancy with FreePBX Distro? I would appreciate any experiences and tips and tricks to making it work.


I looked at it a few years ago, and nice as it appeared, it is like corosync/drbd without the good bits of corosync nor drbd.

So I use these to great effect instead, same hardware commitment, but much more robust and quick switch over.
