What is the maximum number of agents that can be supported by Cisco Unified CCX...

According to the Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Cisco Unified CCX 8.0 can support a maximum of 400 agents when deployed with Cisco Unified Communications Manager. This is the highest capacity option for Cisco Unified CCX 8.0, which requires a dedicated server for the Cisco Unified CCX Engine and a dedicated server for the Cisco Unified CCX Database. The maximum number of agents depends on the hardware configuration, the deployment model, and the features enabled. For example, if Cisco Unified CCX is deployed in a high availability mode, the maximum number of agents is reduced to 300. If Cisco Unified CCX is deployed with Cisco Unified Presence, the maximum number of agents is reduced to 250. If Cisco Unified CCX is deployed with Cisco Unified Intelligence Center, the maximum number of agents is reduced to 150. The maximum number of agents also varies for different versions of Cisco Unified CCX. For example, Cisco Unified CCX 7.0 can support a maximum of 300 agents, while Cisco Unified CCX 9.0 can support a maximum of 500 agents. References: Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 2: Unified CCX Product Overview, Section 2.1: Unified CCX Product Packages, Page 151 Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.1: Unified CCX Deployment Models, Page 252 Cisco Unified Contact Center Express Design Guide, Release 8.0(1), Chapter 3: Unified CCX Architecture and Capacity Planning, Section 3.2: Unified CCX Capacity Planning, Page 293
