This section describes the call flows and provides configuration instructions for the following CVP 
deployment models:

 

The CVP Comprehensive deployment models do not support calls which originate in IP. 

You cannot establish a call with an IP Phone when in Comprehensive mode.

In this deployment model, the CVP acts as the Switch, transferring the call to the Network VRU (Type 
7 flow) and to agents. The CVP Application server is also configured to work with the Voice Gateway 
to provide VRU treatment, which may include ASR/TTS. In this deployment model, both the Voice 
Gateway and the Application Server see two calls:

One for the Switch leg. 

One for the VRU leg.

For the Switch leg, the Gateway simply provides Gateway capabilities from TDM to VoIP. For the VRU 
leg, the Gateway provides VRU voice treatment.

 shows the call flow for this deployment model.

Although 

 shows two Gateways (one where the call arrives and a separate one for the VRU 

leg), these could be the same physical Gateway. Similarly, the CVP Application Server and the PG could 
be the same physical machine. 

For simplicity, the figure does not illustrate a deployment for redundancy and failover. Also, the 
Gatekeeper is not shown.
