Hi, I am hoping to get some deployment insights from people who have implement freeswitch on a large-scale. I have followed the wiki in setting up Xen and Ultramonkey to load balance two freeswitch. But since freeswitch is stateful and two freeswitch can't share info such as fifo, I am wondering if it is a good idea to do just Hot Standby using Linux-HA instead of load balancing. The problem with just Hot Standby is that I can't load balance traffic to multiple machines, which eventually limits the number of concurrent I can serve. Could someone gives suggestion as to how to best approach this problem? Thanks in advance for your help. Best Regards, Pete
