I did some research about Asterisk and High Availability and some sort of
load balancing. The High Availability issue isnn't much of a problem. I did
it with heartbeat en realtime. But the load balancing issue is realy a
problem. You want a load balancer to make decisions based on call ID. The
call ID is stored in the SIP header (layer 7)  and for all I know there are
only a few load balancers that can make decisions based on this layer and
those load balancers are not SIP aware. So for now I don't think load
balancing with *servers could be easily achieved.
