no talk about keeping calls alive during a failover, using sofia recovery functions?

Back in 2010/2011 we did some experiments using corosync
to sync profile status between 2 different freeswitch nodes,
and recovering calls in case of a failover.

this caused ip to be migrated and calls to continue.

The work was part of a graduate thesis in telecommunication engineering.

Since then we never "finalized" that code, even if it works(ed),
mainly because it was of immediate interest/need.

One of the major issue was if system A has 500 calls,
in the event of failover, system B should be able to
start 500 new calls in a very small timeframe (high cps!)

If someone is interested into reading the code and see if
can be somewhat useful, at least the idea, I'll try to
pubish it somewhere (maybe github)
