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

[Wes Sisk]

strictly speaking 3 servers would be adequate.  however, you would allow 
very little room for growth, cti based services, etc.  10k users with 
10k phones and 1 line per phone will fit on 2 subscribers, 1 publisher, 
ccm disabled on the publisher.  this clearly allows no redundancy.

In completing the form pay special attention to your confidence factors, 
extra features, growth options, and redundancy.

Regards,
Wes
