We have 2 gatekeepers in our network, we get a 25/75% split usage between them. I would like to set load balancing so we are closer to 50/50. In looking at the load balancing options it is either CPU or Memory utilization, or number of calls. Our CPU and Memory utilization is pretty low, so I guess we are looking at setting a call threshold. We typically have between 500-600 calls at a time, if I set the call threshold 350 on each gatekeeper, what happens to call 701?
