Call flow analysis is an important part of determining your business requirements. Call flows show you how your calls are handled physically, which drives your equipment requirements. Call flows also help to determine the network routing plan. For sample call flows that are discussed in the context of case studies, see Test Case Studies 
.
These sample call flows were tested and verified in two separate test setups in the contact center environment: Test Bed 1 and Test Bed 2.
Test Bed 1
Test Bed 1—Unified IP IVR test bed, which handles the following call flows:
•
Cisco Unified CallManager (Unified CallManager) Post-Routed call flow
•Cisco Unified Outbound Dialer (Unified OUTD) call flow
Note Cisco Unified Customer Voice Portal (Unified CVP) implemented at Site1/Site4 provides initial call treatment for the Parent/Child call flow, while Customer Response Solutions (CRS) provides call queuing capabilities.
Test Bed 2
Test Bed 2—Unified CVP test bed, which handles the following call flows:
•Unified Customer Voice Portal (Unified CVP) Post-Routed call flow
