If you are using codec G.729 then voice bandwidth with IP overhead (assume RTP header compression) is only 11.2 kbps per call. Then theoretically it is possible to accommodate 5000 users on one end-to-end VLAN - assuming all nodes are IP phones in a modern switched environment. Aggregate bandwidth is only 56mbps. I do not know about CM but I thought I should address this question from a design perspective.
