 The number of premium seats required for a Cisco Unified Contact Center Express system is based on the maximum number of logged in agents plus the number of IVR and email ports needed. In this case, the maximum number of logged in agents is 150, the number of IVR ports needed for outbound calls is 30, and the number of email ports needed for email agents is 20. Therefore, the total number of premium seats required is 150 + 30 + 20 = 180 seats. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 - Module 1: Design a Cisco Unified Contact Center Express System Deployment - Lesson 1: Cisco Unified Contact Center Express Product Overview - Topic: Cisco Unified CCX Product Packages1
