ran into this before on routers, you can put something like that or vrrp 
or carp in front of a pair of systems to fail to the right one BUT there 
isn't only one interface on something like a pbx, it has a lan interface 
and a wan interface, you have to get failover happening on the ALL at 
the same time which is tricky since when you fail one interface that 
sometimes eliminates being able to trigger the other interface to fail 
over since it no longer has any access to get a signal there.

If you want to be able to look at the system to see why it failed you 
have to have some other way in as well.


Every requirement just makes it more complex, and more fun to test.
