Cisco Cisco Unified Customer Voice Portal 10.0(1)

requests arrive at the NAM from the IXC carrier network and are
forwarded, based on specific call properties, to the appropriate
Customer ICM (CICM). A NAM usually contains only a small
configuration that allows it to directly route a subset of calls and
dispatch other calls to the appropriate CICM. The NAM receives route
responses from all CICMs and forwards them to the carrier network.

In this call flow model, Unified CVP acts as the Switch, transferring
the call to the Network VRU and to agents. The Unified CVP IVR

Service in the Operations Console is also configured to work with the
VoiceXML Gateway to provide VRU treatment, which might include
ASR/TTS and VXML Server applications.

In this call flow model, Unified CVP is deployed at the NAM where
it acts as the Switch, transferring the call to the Network VRU (using

the Correlation ID transfer mechanism) and to agents. The Unified
CVP IVR Service in the Operations Console is also configured to work
with the VoiceXML Gateway to provide VRU treatment, which might
include ASR/TTS and VXML Server applications.

In this call flow model, Unified CVP works with the Voice Gateway
to act as the VRU; VRU voice treatment is provided by the Gateway

and can include ASR/TTS and VXML Server applications. This model
would be used when call switching is provided by some component
other than Unified CVP, such as a Unified ICME NIC.

In this call flow model, the Unified CVP Call Server is deployed at
the CICM level to act only as the VRU leg for the call. The VRU voice

treatment is provided at the Voice Gateway, and might include
ASR/TTS and VXML Server applications. This model would be used
when call switching is provided by some component other than Unified
CVP, such as a Unified ICME NIC.

Note: The CICM is the Customer ICM. In the optional two-tier service
bureau (carrier) configuration, the CICM is the tier providing the
carrier customer-specific routing function. CICMs receive
customer-specific call route requests from the NAM; they typically
perform more elaborate scripted call routing using customer-specific
advanced services or agent and skill context.

In this call flow model, Unified CVP is deployed as a Network VRU
at the NAM. The Unified CVP IVR Service in the Operations Console

works with the Voice Gateway to act as the VRU; VRU voice treatment
is provided at the Voice Gateway and can include ASR/TTS and
VXML Server applications. (This call flow model is used when Unified
CVP is connected to the NAM.) This model would be used when call
switching is provided by some component other than Unified CVP,
such as a Unified ICME NIC.
