That's a nice and simple possiblity I haven't though of. I think this 
will also work fine in a HA-setup if you use two SER/SEMS-Pairs (one 
master and one slave) as conference servers and perform the failover 
handling (switching to the slave server on SIP timeout) in the failure 
routes of the backend SERs.
