Mark: This is not the case of 100 users. I have 20K users. But I expect my system to handle 100 simultaneous users. I'm not applying 3:1 rule over 20K users as my users won't use my system for calling purpose. As such my system is there for them just to record/listen/delete their voicemails, and it won't have much frequency.
