Unfortunately we are under NDA and I cannot give more details. Let's just say at this time we do not have a test environment to test above 5000 calls under a variety of different business models that our customers use. If anyone has such an environment, and a proven track record of running load testing and tuning, I'd be interested in hearing from them. Otherwise, we'll probably build it ourselves.
