[cisco-voip] Cluster servers: Cisco Unified Communications Manager Capacity Tool V4.1

[Wes Sisk]

I have seen 7500 phones on a single server.  It was for testing purposes 
so they were all basic phones with single lines and no shared lines.  
Note that there specifically was no security enabled.  Security cuts 
scalability significantly.  Also note this was testing on CM6.1(2).  
There are several defects in earlier 5.x and 6.x versions that very 
specifically limited scalability.

7500 phones on a single server represents 100% utilization.  Generally 
that is not a good way to start a deployment.
