Hi, I can't find much info on setting up a redundant or heavy load FreeSwitch implementation. Are there any links apart from: http://wiki.freeswitch.org/wiki/Enterprise_deployment ? I imagine the entry level solution is to have two FS boxes configured identitcally, with redundant SBC software (recommendations?) in front, passing the calls to the primary FS box, or the backup FS box if the primary is not responding. Is that the easiest solution? What about a situation of having a level of concurrent calls beyond what one FS box can handle? I realise that would be a very large number of concurrent calls, but we would need a good plan on how to scale the systems. Are there recommendations for load balancing solutions? Either soft or hardware? My guess would be having 3 + 1 spare FS servers would work, where calls are distributed accross 3 FS boxes by a load balancer with one spare in event of failure. Also how would a FS box at max capacity behave? Does FS monitor available resources and reject the excess calls that it can't handle? Or would the load balancer have to be configured with the maximum number of calls per box? Would love to hear some experiences of deploying FS with failover & high load. Thanks Ash
