You need to use something to keep track of whether each box is reachable
and what each is doing.  There a lots of ways of doing that, including
custom network applications, shared networkable databases, shared nfs,
et alia.

Then each node needs a bit of logic to use that data to determine what
to do with any given event.

As one example, if a sip server gets an invite which directs on to an
existing conference, it needs to know which asterisk is handling that
conference, so that it can send the invite there.

A shared database is required, but whether it is a custom application, a
networkable db or a local db stored on a networked file systems is
something anyone writing the code needs to choose.
