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.<br><br><div><span class="gmail_quote">On 1/4/06, <b class="gmail_sendername">Kevin P.
