Chapter 3. Functional Deployment Models and Call Flows - Pg. 47

Chapter 3 Functional Deployment Models and Call Flows This chapter covers the following subjects: Functional deployment models: Standalone, Call Director, Comprehensive, VRU-only. Detailed call flows: Call flow details for each Functional Deployment Model. Unified CCE interactions: Network VRUs in Cisco Intelligent Contact Management Enterprise and IP originated calls with Cisco Unified Communications Manager. Functional Deployment Models As discussed briefly in the previous chapter, Unified CVP has some well-defined and commonly referenced functional deployment models. This chapter provides more details for these models and examines what each model accomplishes, its call flow, and even which native and non-native components are used. Understanding these models is critical to designing, implementing, and troubleshooting a Unified CVP solution. The chapter ends with a discussion that encompasses Unified CVP and its relationship and interac- tions with Unified CCE components, such as Unified ICM and Cisco Unified Communications Manager. Standalone Model Although this model is the simplest of all the functional deployment models, the flexibili- ty available in Unified Call Studio applications is astounding. This model gives an organi- zation the capability to replace legacy IVR systems using applications built using Unified Call Studio and hosted via the Unified CVP VoiceXML Server. The standalone model pro- vides a standalone, automated self-service IVR solution that callers can access via TDM and VoIP terminating at Unified CVP's Ingress voice gateways. In addition callers could also access this solution via VoIP endpoints. Figure 3-1 shows the components used with this solution and their protocols.
