5.2 Unified ICM/Unified Contact Center Operating Conditions
Except when explicitly specified, the Unified ICM/Contact Center hardware selection described in this section is based
on the following operating conditions. In determining how to size a Unified ICM or Unified CC software
implementation, it is important to consider the factors listed here. While there are additional variables that would impact
system capacity, Cisco has chosen a representative subset and provided a set of values on which the sizing limitations
herein are based.
